When water in a river or stream moves quickly, it can lift up rocks from the bottom of that body of water. When the rocks drop back down they bump into other rocks, and tiny pieces of the rocks break apart
Answer: Option (C) is the correct answer.
Explanation:
Stoichiometric coefficients represents the number of individual atoms involved in the chemical equation.
As a result, stoichiometric coefficients help in balancing the equation because an equation can only become balanced when number of reactant molecules equal the number of product molecules or vice versa.
Therefore, we can conclude that a chemical equation can be used to solve stoichiometry problems provided that it includes the coefficients that are needed for balancing the equation.
The percentage of sugar in the solution is 1%
To solve this question, we need to find the percentage of 6 out of 600.
Data given;
- mass of sugar = 6g
- mass of solution = 600g
<h3 /><h3>What is Percentage</h3>
This is the rate or proportion of a substance in the total value and multiplied by 100.
The percentage of sugar in the solution is calculated by
![\frac{6}{600} * 100 = 1 %](https://tex.z-dn.net/?f=%5Cfrac%7B6%7D%7B600%7D%20%2A%20100%20%3D%201%20%25%20)

Answers are:
1) Each sodium atom loses one electron.
2) The charge of the chloride ion in NaCl is -1.
Oxidation reaction: Na⁰ → Na⁺¹ + e⁻ /×2; 2Na⁰ → 2Na⁺¹ + 2e⁻.
Reduction reaction: Cl₂⁰ + 2e⁻ → 2Cl⁻.
Sodium change lose electrons and change oxidation number from 0 to +1 (oxidation). Chlorine change oxidation number from 0 to -1 (reduction reaction).
