Answer:
67.5%
Explanation:
Step 1: Write the balanced equation for the electrolysis of water
2 H₂O ⇒ 2 H₂ + O₂
Step 2: Calculate the theoretical yield of O₂ from 17.0 g of H₂O
According to the balanced equation, the mass ratio of H₂O to O₂ is 36.04:32.00.
17.0 g H₂O × 32.00 g O₂/36.04 g H₂O = 15.1 g O₂
Step 3: Calculate the percent yield of O₂
Given the experimental yield of O₂ is 10.2 g, we can calculate its percent yield using the following expression.
%yield = (exp yield / theoret yield) × 100%
%yield = (10.2 g / 15.1 g) × 100% = 67.5%
Yes a compound a thing that is composed of two or more separate elements; a mixture.

</span>Mechanical energy is the top suject while it has two types: Kinetic energy which is the energy in motion and potential energy which is the energy in reserve. The measure of both energy in motion and reserve is called Joules. Joules then is the International System of Measurement unit for energy, this is mainly used to account for scaling energy in all aspects.<span> </span>
