Answer:
The particles start moving faster and expand making the ball expand.
Explanation:
Answer:
Overall reaction equation is:
Cl2(g) + CHCl3(g) --> HCl(g) + CCl4(g)
The intermediates are Cl(g), CCl3(g).
Rate law= ka^1/2 c
Explanation:
This reaction is a non elementary reaction. A non elementary reaction is one that does not take place in a single reactive encounter. In other words, the reaction is comprised of many steps.
The overall reaction equation is the sum of all the reaction steps after all intermediates have been cancelled out. The rate law is obtained from the slowest step in the reaction sequence.
The 0.05 moles of required to make 1 L of solution in which the concentration is 0. 15 M.
Calculation,
The Sodium phosphate dissolves as follows:
→
To make 1. L of solution in which the concentration is 0. 15 M
The morality of = 0.15 M = number of moles / volume in lit
The morality of = 0.15 M = number of moles /1 Lit
number of moles of = 0.15 mole
The mole ratio is 1: 3
It means, the 1 mole of required to form 3 mole of
So, to form 0.15 mole of = 1×0.15 / 3 moles of required.
Hence, number of moles of required = 0.05 moles.

Answer:
10.3
Explanation:
The pH of a substance is a number spanning from 0 to 14.
A substance with pH between 0 and 7 is said to be acid, while a substance with pH between 7 and 14 is said to be basic. A substance with pH of 7 is a neutral substance.
The pH of a solution can be calculated using the formula:
where
is the concentration of hydronium ion in the solution
In this problem, we have a concentration of hydronium ion in the solution equal to
Therefore, we can apply the formula above to calculate the pH of the solution, and we find:
So, the pH of this solution is 10.3.
