If a reaction is at equilibrium and you add reactants what happens?
If you continuously add reactants even after the reaction has attained the equilibrium then according to Le Chatelier's principle, the reaction will again proceed in forward direction in order to neutralise the reactants and once again the attain the state of equilibrium.
Which type of air front is always forced up?
A cold front is a type of air front that is always forced up as it moves into an area of warmer air. This lifting process can result in the formation of thunderstorms and other types of severe weather.
How many sunny days per year in sion Switzerland?
Sion, Switzerland, typically experiences around 190 sunny days per year. This can vary slightly from year to year, but the region generally enjoys a good amount of sunshine.
Where can scientists recover DNA from a victim or suspect?
Scientists can recover DNA from a victim or suspect from various sources such as blood, hair, skin cells, semen, saliva, and other bodily fluids. These samples can be collected from crime scenes, clothing, personal items, or directly from the individual through a simple cheek swab. The recovered DNA can then be analyzed and compared to databases to identify potential matches.
Meteorite containing more stone than iron?
Chondrites are a type of meteorite that are composed mostly of rock and minerals, with very little iron-nickel content. These meteorites are some of the most common types found on Earth and are believed to be remnants of the early solar system. Chondrites can provide valuable insights into the formation and evolution of our solar system.
Does taking water out of an equilibrium reaction change the equilibrium constant?
No, the equilibrium constant is independent of concentration as long as the ratio of products and reactants remains as is.
It can be effected by anything that would influence the ratio of products and reactants, such as changes in temperature or the addition of a catalysis.
Which is expected to have the largest dispersion forces CO2 C8H18 N2 C2H6?
C8H18 (octane) is expected to have the largest dispersion forces among these molecules due to its larger number of electrons and greater molecular weight, leading to stronger London dispersion forces.
What is the largest air force base in the world?
The Eglin Air Force Base is the largest Air Force base in the free world. Eglin Air Force Base is the home of the Air Armament Center (AAC) and is one of four product centers in the Air Force Materiel Command (AFMC).
Taking in fluids so that the body functions properly?
Drinking enough fluids helps maintain blood volume, regulate body temperature, and support digestion and nutrient absorption. Hydration is essential for transporting nutrients and waste products within the body and supporting various bodily functions. Drinking water also helps lubricate joints and protect sensitive tissues.
What factors influence a echinoderms growth?
Factors such as availability of food, water quality, temperature, and genetics can influence the growth of echinoderms. The presence of predators, competition for resources, and environmental stressors can also impact their growth rates. Additionally, developmental stages and life history strategies play a role in determining the growth of echinoderms.
What are the chemicals that influence the physiology or behavior of the members of a species?
Chemicals that influence physiology or behavior, known as pheromones, are released by organisms to communicate with others of the same species. These chemicals can trigger various responses such as mating behaviors, territorial marking, and alarm signaling. Pheromones play a crucial role in coordinating social interactions and reproductive activities within a species.
How does the air hole affect the type of a flame?
The size of the air hole can affect the flame by controlling the amount of oxygen available for combustion. A larger air hole can result in a more efficient and hotter flame, while a smaller air hole may lead to incomplete combustion and a sooty flame. Adjusting the air hole can help optimize the burning process for different types of fuels.
What may be the reasons for any air crash?
The general categories for airplane crashes include:
Weather - Poor visibility. Icing conditions. Some pilots are not trained or equipped to fly at night and find themselves having to continue flying to reach an airport after it gets dark. An example of this John Kennedy's plane that was lost at night in the ocean near Marthar's Vineyard.
Mechanical - This can be a failure of a part during normal service. Most aircraft systems have built-in redundancy so that a failure of one part will not create an unsafe condition. Some mechanical failures is due to bad maintenance; such as someone forgetting to tighten a bolt.
Pilot Error - this can vary from not paying attention to his instruments or watching for other a/c. People are only human so many accidents are attributed to poor judegment of the pilot. For example; the weather may be getting bad but the pilot chooses to fly into the storm. Larger passenger airliners have 2 or more flight crew which helps eliminate some human errors.
Air Traffic Controller - Sometimes the traffic controller gives the "Clear to Takeoff" or similar instructions that result in an accident.
A new one is called:
Cockpit Management - Airlines now stress that the Pilot In Command should keep control of the situation and accept inputs from his crew without judging them. If the Pilot In Command begins to ignore or judge the recommendations of the crew, the crew will not function as a team and someone will over-look something that will lead to an accident.
Fuel Starvation - This is really a subset of Pilot Error but it can be the result of several factors.
I highly recommend you go to the website of NTSB and check out their Aviation section. You can read their findings for accidents that go back years and years. They have a menu for Montly Accident Reports which lets you select a Year and then a Month and then any accident you want to read about. This includes small Cessna's, gliders, helicopters etc.
What is the first step in canning apples in a water bath?
The first step in canning apples in a water bath is to prepare the canning jars and lids by washing them in hot, soapy water and sterilizing them in boiling water. This will ensure that your jars are clean and ready to be filled with the apples for canning.
Acetonitrile is unlikely to be more toxic than methanol, as the latter is extremely toxic. Acetonitrile, also known as methyl cyanide, is quite unlike the poison "cyanide", because the poison is a salt of hydrocyanic acid and has free cyanide ions in solution. Acetonitrile has no free cyanide ions. The breakdown products of acetonitrile / methyl cyanide will be acetic acid and ammonia, which will form harmless ammonium acetate. In the short term, however, acetonitrile like any other organic solvent will have narcotic effects, causing dizziness and drowsiness, and the solvent could kill in large enough amounts.
How many aircraft are in the air at any one time around the world?
Saturday, the busy weekend before Christmas 2007, there are 5400 aircraft flying over USA. Don't have the numbers for the entire world.
Can you ship photovoltaic cells?
Yes you can ship PV panels. However it makes sense to buy cells (collected together these make a PV panel), locally.
It costs energy to make the panels as well as transport them. They will also be harvesting energy over a 20-30 year lifespan. It makes sense to try and keep the environmental costs as low as possible in producing and transporting them to maximise the amount of energy gained overall.
Years ago the bulk of PV panel production occured in Japan, USA and Germany. Whilst this is still largely the case, other countries are starting up production.
It is a common myth that it takes more energy to make a panel than it will harvest in its life time. Now it is generally estimated that a panel will pay for itself in energy terms in between 2-4 years Yes you can ship PV panels.

Factors that may influence the development of self concept among entrepreneurs?
Factors that may influence the development of self-concept among entrepreneurs include upbringing and early experiences, personality traits such as self-confidence and risk-taking, feedback from mentors or peers, and external validation from business successes or failures. These factors can shape an entrepreneur's self-perception, beliefs, and attitudes towards themselves and their ventures.
How doese the various agencies of socialization contribute to personality development?
Various agencies of socialization such as family, school, peers, media, and community contribute to personality development by presenting individuals with social norms, values, beliefs, and behaviors that are internalized through interaction and observation. These agencies help shape one's self-concept, identity, and social skills through socialization processes like rewards, punishments, modeling, and reinforcement. By providing different perspectives, experiences, and interactions, these agencies influence the development of an individual's personality traits, attitudes, and behaviors.
Development is very important in the world. Without development, everything would be so boring. There would be no aim, no goal to achieve. Everything would die very soon.
What percentage of your gross income should go towards health insurance?
A general guideline is to allocate around 5-10% of your gross income towards health insurance premiums. However, this can vary based on individual circumstances such as age, health status, and coverage needs. It's important to evaluate your budget and prioritize health insurance as necessary.
What two factors influenced the development of sociology?
Development of sociology was precipitated at the onset of agrarian revolution.As new methods of agriculture were being invented,industries grew because now production was in surplus and human population was not enough to convert them into consumables...Industrialization in itself gave rise to settlement around the industries.People moved from their former settlement to centers where industries were located,this in modern terms is called 'URBANIZATION'.Urbanization brought about several reppurcations in way of life,changes in culture,is what now brought about interest ,this interest in the society in respect to how this changes affect and are addressed is what is called sociology.So in a nutshell,agrarian revolution,industrialization and urbanization are the contributorieS to sociology
What percentage of your gross income should go towards rent?
No more than a third of your gross annual income should go towards housing. As for rent, you should not spent anymore than 25% of your gross income. Housing - This expense should include mortgage, insurance, gas, electricity, maintenance, and phone. (according to crown.org budget guide) Rent or your monthly mortgage payment plus each of the above should never exceed 36%. 1/3 is generally a good rule just as with the 1st answer, but don' t forget that the number includes the other housing expenses.
To what extent do nonstate actors exert independent influence on international relations?
The influence of independent actors on international relations can vary from nothing at all to something outside calculation. Plenty of people acting independently, working as individuals and as groups, do things on a daily basis that have no effect whatsoever on international relations. But in the case of the extremists who plotted and executed the acts of 9-11, they catalyzed monumental changes in international relations and policy, and could fairly be said to have changed the course of history. Certainly there are many other groups or organizations whose actions fall somewhere between these extremes. The Red Cross, Peace Corps, Doctors Without Borders, and other such groups are but some of a countless number of organizations that could be cited as being "nonstate actors" having a variable effect on international relations. The broad variation in the acts of independent operators can have widely varying effects on international relations.
