When you have to write about what you do in your spare time, you need to write about your hobbies.
Hobbies are activities that you do in your spare time just because you like them and not because you are obligated to do them.
For instance, these are some examples of sentences about what I do in my spare time:
- Juego al tenis en mi tiempo libre.
- Me gusta escuchar música en mi tiempo libre.
- Cuando tengo tiempo libre, me junto con mis amigos.
It's important to decide what you want to write about and once you write them, check if they are grammatically correct.

When the PH is 7.0, the hydronium Ion Concentration is gotten as; [H3O+] = 1 × 10^(-7) M
<h3>How to find the Concentration of an Ion? </h3>
The formula to find the pH of an Ion concentration is;
pH = - log [H3O+]
where;
[H3O+] is the molar concentration of hydronium ion.
We are told that the pH is 8.0. Thus;
8.0 = - log [H3O+]
10^(-8) = [H3O+]
[H3O+] = 1 × 10^(-8) M
Thus, when pH = 7.0, we have;
7.0 = - log [H3O+]
[H3O+] = 1 × 10^(-7) M
Complete question is;
When the fish-tank water has a pH of 8.0, the hydronium ion concentration is 1.0 × 10-8 mole per liter. What is the hydronium ion concentration when the water has a pH of 7.0?

Answer:
friendly to others.
Explanation:
I took the test and got it correct.
Answer:
150°C
Explanation:
T1 = 7.00 C = 7 + 273 = 280 K
V1 = 49.0 ml
V2 = 74.0 ml
T2 = ?
Under constant pressure, V1/T1 = V2/T2, so
T2 = T1 * (V2/V1) = 280 * (74/49) = 423 K = (423 - 273) C = 150 C
