Answer:
The catalyzed reaction will take time of 
.
Explanation:
According to the Arrhenius equation,
The expression used with catalyst and without catalyst is,
where,
= rate of reaction with catalyst
= rate of reaction without catalyst
= activation energy with catalyst = 59.0 kJ/mol = 59000 J/mol
= activation energy without catalyst = 184 kJ/mol = 184000 J/mol
R = gas constant
T = temperature = 
Now put all the given values in this formula, we get:
The reaction enhances by 
when catalyst is present.
Time taken by reaction without catalyzed = 3900 years
Time taken by reaction with catalyzed = x
The catalyzed reaction will take time of .
Answer
The Density of a substance can change if its location changes.
Explanation
All the statements are TRUE except
The Density of a substance can change if its location changes.
This is because density is an intensive property, that is regardless of the object's shape, size, or quantity, the density of that substance will always be the same. Even if you cut the object into a million pieces, they would still each have the same density.
Therefore, the statement that is FALSE is
The Density of a substance can change if its location changes.
Answer:.603moles
Explanation:do given over 1 so 66.38 over 1 then multiply by 1 over 110.035344(the atomic mass of KMnO) and then you get the answear
Answer:
Explanation:
Hello there!
In this case, according to the reaction:
Thus, since there is a 4:2 mole ratio of P to P2Cl5 and the molar mass of the later is 239.2125 g/mol, we obtain the following mass as the produced one:
