C. It stays the same as energy is added.
Answer: 4 water from rain and snow that travels to streams im pretty sure!
Temperature can be calculated using the average kinetic energy. The ideal gas equation is being related to the average molecular kinetic energy.

By substituting and simplifying, we eventually get the equation.

KE = (3/2)RT</span>
T = 3866 x 2 / 8.3145 x 3 = 309.98 K or 36.83 degrees Celsius
Answer:
6. Double replacement "DR"
7. Double replacement "DR"
8. Combustion "C"
9. Single replacement "SR"
10. Decomposition "D"
Explanation:
- number 6 and 7 are double replacements because if you look at the compounds in the reactants vs the products, it is evident that there has been a replacement between Na & K in number 6 and Mg & Li in number 7, a "DR" occurs when the anions and cations in 2 molecules switch places to form 2 new compounds.
- number 8 is a combustion reaction because a combustion reaction occurs when oxygen is combined with another compound to form water and carbon dioxide (H2O & CO2).
- number 9 is a single replacement reaction because the Pb and Fe have simply switched places, "SR" are when an element trades with another to form a new compound and the element that was swapped.
- number 10 is a decomposition because it can be observed that the compound in the products is being broken down into the molecules or compounds that it is made up of, started with one and finished with 2
Chemical equilibrium is a dynamic equilibrium that is affected by changes in temperature, concentration and pressure
<h3>What is chemical equilibrium?</h3>
Chemical equilibrium is a dynamic state in a chemical reaction in which the rate of forward reaction is equal to the rate of backward reaction.
For a reaction in equilibrium, the following factors affect equilibrium:
- temperature
- pressure
- concentration
The principle of chemical equilibrium states that in an isolated system in equilibrium, equilibrium will shift to annul any constraint applied in the system.
Therefore, chemical equilibrium is dynamic and is affected by temperature, concentration and pressure.
