In order to solve this problem you need to consider the states of matter and the amount of products.
If there are more products than reactants than there is an increase in entropy.
States of matter: increasing the motion of particles increases entropy.
Molecular movement:
Solid<Liquid<Gas
Changing states of matter from left to right would be an increase in entropy.
Changing states of matter from right to left would be a decrease in entropy
The answer is number 3
The answer is b. The sum of the individual gas pressure in the mixture
Answer:
1.57 x 10⁷m
Explanation:
Given quantity is;
1.57 x 10¹⁴nm
Now;
1 nm = 10⁻⁹
So, let us convert this given quantity;
1 nm = 10⁻⁹
1.57 x 10¹⁴nm will give 1.57 x 10¹⁴ x 10⁻⁹ = 1.57 x 10⁷m
Explanation:
First lets calculate the volume of the silver cube The length of a side = 0.62 m Volume
2H2O+O2--->2H2O2
8.5 gm H2O2=0.25 mole
hence H2O is also 0.25 mole i.e.4.5 gm
O2is 0.125 mole i.e.4 gm
