Answer:
It will take 6486.92 minutes for [H2O2] to fall from 0.95 M to 0.33 M
Explanation:
The order of reaction is defined as the sum of the powers of the concentration terms in the equation. Order of a reaction is given by the number of atoms or molecule whose concentration change during the reaction and determine the rate of reaction.
In first order reaction;
where;
a = concentration at time t
= initial concentration
and k = constant.
t = 6486.92 minutes
Answer:
The first is true
The second is true IF the statement means that the human body contains energy
The third is true
The fourth is false
An old penny rusting, remember you can’t undo a chemical change
Both the increase in the boling point and the depression on the freezing point are colliative properties.
This is, they are proportional to the number of particles dissolved in the solvent, which is measured by the molality of the solution and the factor i (Van'f Hoff).
The answer to the question is that 1) the boling point of a solution of water and calcium chloride at standard pressure will be higher than the normal boiling point of pure water, and 2) the freezing point of a solution of water and calcium chloride at standard pressure will be lower than the normal freezing point of pure water.
