Answer:
Because it keeps track of all the elements
mole is the standardized form of molarity
Answer:
The new pressure of the gas comes out to be 400 KPa.
Explanation:
Initial volume of gas = V =
Initial pressure of gas = P = 120 KPa
Final volume of gas = V' =
Assuming temperature to be kept constant.
Assuming final pressure of the gas to be P' KPa
New pressure of gas = 400 KPa
Answer: Rate of decomposition of acetaldehyde in a solution is
Explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
For a reaction :
k= rate constant
x = order of the reaction = 2
Thus rate of decomposition of acetaldehyde in a solution is
