Achemist is using a solution of hno3 that has a ph of 3.75.

what is [h+] for the solution?

× 10n m
n =

[H⁺] = 1.8 ×10⁻⁴ mol/L

Explanation:

Given data:

pH of HNO₃ = 3.75

[H⁺] = ?

Solution:

Formula:

pH = -log [H⁺]

Now we will put the values.

3.75 = -log [H⁺]

[H⁺] = 10⁻³°⁷⁵

[H⁺] = 1.8 ×10⁻⁴ mol/L

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
