Answer:
2.16 × 10⁻³
Explanation:
Step 1: Given data
Concentration of the acid (Ca): 0.260 M
Acid dissociation constant (Ka): 1.80 × 10⁻⁵
Step 2: Write the acid dissociation equation
HC₂H₃O₂(aq) + H₂O(l) ⇄ C₂H₃O₂⁻(aq) + H₃O⁺(aq)
Step 3: Calculate the concentration of H₃O⁺ at equilibrium
We will use the following expression.
![[H_3O^{+} ]= \sqrt{Ka \times Ca } = \sqrt{1.80 \times 10^{-5} \times 0.260 } = 2.16 \times 10^{-3}](https://tex.z-dn.net/?f=%5BH_3O%5E%7B%2B%7D%20%5D%3D%20%5Csqrt%7BKa%20%5Ctimes%20Ca%20%7D%20%3D%20%5Csqrt%7B1.80%20%5Ctimes%2010%5E%7B-5%7D%20%5Ctimes%200.260%20%7D%20%3D%202.16%20%5Ctimes%2010%5E%7B-3%7D)
I believe that the answer to the question provided above is light energy is trapped, and by certain enzymes then transformed to chemical energy.

Answer:If a liquid is heated the particles are given more energy and move faster and faster expanding the liquid. The most energetic particles at the surface escape from the surface of the liquid as a vapour as it gets warmer. Liquids evaporate faster as they heat up and more particles have enough energy to break away.

Answer:
Explanation:
Nuclear fusion of a form of nuclear reaction in which two small atomic nuclei combines to form larger ones with the release of a large amount of energy.
For example;
²₁H + ²₁H → ⁴₂He + Energy
The energy released in a nuclear reaction provides the needed temperature for another set of ²H atoms to fuse. This process in turn yields another ⁴He with the release of a lot of energy. Thus, enormous release of energy accompanies a nuclear reaction.
It is based on this principle that an hydrogen bomb is formed.
Answer:
I'll do #1
Explanation:
Solids:They are molecules packed together and contain the least amount of kinetic energy
Liquids:Flows frequently in space, of constant volume
Gasses:Gas is made up of atoms,mostly made up of a mixture of air
Plasma:Largest part of your blood
Hope This Helppps!!Good Luck!!!
