What else can I help you with?
Why is it important to write a balanced reaction before determining the equilibrium expression and equilibrium concentrations?
So you can use the coefficants to go from one substance to another
What temperature and pressure correctly describes standard temperature and pressure?
Standard temperature and pressure conditions are: Temp: 273K or 0°C Pressure: 100k or 1 bar STP is 273K or 0oC and 1 bar or 100kPa
Massive releases of methane hydrate from the ocean floor would cause which atmospheric gas to decrease?
Methane. Methane itself has a half life of 7 years in the atmosphere, decomposing to water (H2O) and the methy radical CH3. (i.e. amount of methane in atmosphere decreases by half every 7 years).
Why negative temperature in j thermocouple?
A negative temperature reading in a J-type thermocouple can be caused by a reversed connection of the thermocouple wires, which leads to the temperature measurement being incorrect. Check the polarity of the wires and make sure they are correctly connected to avoid this issue.
What is the of lead when it melts?
Because it is a metal, and all metals melt if their temperature reaches a high enough level. In the case of lead, this melting point is 621oF (327oC), lower than many other metals. The melting is caused when the forces associated with the thermal motion of the free electrons exceed the electromagnetic forces holding the electrons and nuclei in a solid lattice structure. The relatively low electromagnetic forces in solid lead contribute to both its softness and its low melting point.
Which of the following correctly matches the equilibrium receptor to the type of equilibrium it monitors?
maculae/static equilibrium
What correctly describes any chemical reaction that has reached equilibrium?
At equilibrium, the rate of the forward reaction is equal to the rate of the reverse reaction. The concentrations of reactants and products remain constant, although they are still reacting. The equilibrium position can be affected by changes in temperature, pressure, or concentration.
What correctly described a reaction that has chemical equilibrium?
We don't answer questions from printed or copyrighted materials.
How do you spell associated?
That is the correct spelling of "association" (a group, or a connection of some sort).
What are the major and minor gasses in the atmosphere from mars?
Mars has an extremely thin atmosphere that is primarily Carbon Dioxide, if I recall correctly.
If you are in equilibrium your net force is greater than zero?
If I understand you question correctly, no, the net force would, in fact, be zero.
When any object is in mechanical equilibrium what can be correctly said about all the forces that act on it must the net foce necessarily be zero?
Yes.
Why is it important to write a balanced reaction before determining the equilibrium expression and equilibrium concentrations?
So you can use the coefficants to go from one substance to another
What are some common challenges encountered when solving Hardy-Weinberg equilibrium problems?
Some common challenges when solving Hardy-Weinberg equilibrium problems include understanding the concept of genetic equilibrium, calculating allele frequencies accurately, accounting for factors like mutation, migration, genetic drift, and natural selection, and interpreting the results correctly.
Define the natural rate of employment?
The natural rate of unemployment is the rate which occurs when inflation is correctly anticipated. This level of unemployment occurs when the labour market is in equilibrium.
What is the pH of a solution whose H3O is 1 x 10-6 M?
pH = 6.0 at 25 oC when water equilibrium is taken into account correctly.
Which row in the chart correctly identifies characteristics that can be associated with the members of this food chain?
it’s 3
