Answer:
the answer is 5 m/s² and you can also divide jt by 2 to get its fully ans
Answer:
C. Decreasing the temperature of the system.
Explanation:
Decreasing the temperature of the system increases the chance of a reaction when two molecules collide.
Endothermic reactions are reactions that proceed by the absorption of heat (energy) while exothermic reactions involve a release of energy.
a) Formation of frost on a car window in winter is an exothermic process as heat is liberated when liquid water freezes to form crystals
b) Formation of water condensate on a glass of ice water is an endothermic reaction since heat is absorbed by the cold water from the glass container thereby cooling it.
c) A decrease in the temperature as ammonium nitrate is added to water is an endothermic reaction
Answer:
56.9 mL
Explanation:
To solve this problem, we can use the equation of state for an ideal gas, which states that:
where
p is the pressure of the gas
V is its volume
n is the number of moles in the gas
R is the gas constant
T is the absolute temperature of the gas
For a gas undergoing a transformation, n and R remain constant, so we can rewrite the equation as:
where in this case:
is the initial pressure of the gas
is the initial volume
is the initial temperature of the gas
is the final pressure (at STP)
is the final temperature (at STP)
Solving for V2, we find the final volume of the gas:
