What kind of experiment would explain separation of salt water solution?
evaporation or boiling!!!
Explain fractional distillation and how it is used in refining oil?
Fractional distillation is a technique used to separate liquids with different boiling points. It is used in refining oil, whereby different types of oils are separated according to their different boiling points.
A cook decided to add salt to a pot of soup that was boiling on the stove. As soon as the salt was added the soup stopped boiling. Explain why this happened?
Adding the salt to the soup raised the boiling point of the water in the soup. This is a well known phenomena in thermodynamics that when you add a solute (especially one with a much higher boiling point than the solvent) to a solvent (which is water in this case) you will initially increase the temperature at which the resulting solution will boil - and incidentally also depress the temperature at which it will freeze.
Explain how a reduction in the amount of sunlight in an ocean ecosystem could cause greater competition among the consumers?
A reduction in sunlight can lead to decreased primary productivity, limiting the availability of food sources for consumers in the ocean ecosystem. This scarcity of resources can cause increased competition among consumers as they vie for the limited food supply. This heightened competition may result in some species outcompeting others, leading to shifts in the ecosystem's structure and dynamics.
Explain chemical equilibrium shifts to favor products?
Chemical equilibrium shifts to favor products when the concentration of products is decreased or the concentration of reactants is increased. This can be achieved by removing some of the product or adding more reactant to the system. Le Chatelier's principle states that a system at equilibrium will respond to changes in concentration, pressure, or temperature by shifting in a direction that helps restore equilibrium.
How is stockholder's equity increased by revenues and decreased by expenses?
Briefly explain why the owner's investment and revenues increased owner's equity, while withdrawals and expenses decreased owner's equity
Explain why the boiling points of hydrocarbons that have the generic formula CnH2n plus 2 increase with molecular weight?
because the induced dipole-induced dipole forces are increased.
How can music relieve stress?
Levels of endorphins, natural pain relievers, are increased while listening to music, and levels of stress hormones are decreased. This latter effect may partially explain the ability of music to improve immune function
Explain why blackboards are not scratched by chalk but are scratched by the sand embedded in the chalk?
The hardness of sand is higher.
The plow revolutionized farming and increased production?
Explain ways the plow revolutionized farming and increased production.
What kind of experiment would explain separation of salt water solution?
evaporation or boiling!!!
What is the hardness of a mineral that scratches gypsum?
The mineral that scratches gypsum has a hardness greater than 2 on the Mohs scale. Gypsum has a hardness of 2 on the Mohs scale, so any mineral that can scratch it must have a hardness greater than 2.
Explain why mercury will need the most energy to boil?
Because it has the highest boiling point. -sorry if it is wrong-
Explain how the discovery of oil in Persia increased the value of Ottoman territory?
by study
Can you use the same multiplication fact to find 3 times 80 and 4 times 60 explain?
Yes because one number has been increased by a 1/4 while the other number has been decreased by a 1/4 So 3*80 = 240 and 4*60 = 240
Explain how liquids reach a point where they boil?
They 'reach' it by heating up the liquid till boiling point is reached.
Give and explain 7 effects of Irresponsible Adolescent Behaviors on the community?
Give and explain 7 effects of Irresponsible Adolescent Behaviors on the community? Increased crime rates: Irresponsible adolescent behaviors, such as vandalism and theft, can lead to an increase in criminal activity in a community. Damage to public property: Adolescents who engage in behaviors such as graffiti and littering can cause damage to public property, leading to costly repairs and maintenance. Decreased property values: Irresponsible adolescent behaviors can also lead to a decrease in property values in a community. This can make it difficult for residents to sell their homes or attract new buyers. Tension and conflict with law enforcement: Adolescents who engage in irresponsible behaviors may come into conflict with law enforcement, leading to increased tension and mistrust between the community and the police. Substance abuse: Adolescents who engage in substance abuse can lead to a variety of negative effects on the community, including increased crime rates and decreased property values. Loss of community morale: Irresponsible adolescent behaviors can lead to a loss of community morale, as residents may feel unsafe or uncomfortable in their own neighborhood. Negative impact on businesses: Irresponsible adolescent behaviors can also negatively impact local businesses by driving customers away and decreasing overall economic activity in the community.
