Answer:
<h3>Hydrogen gas is the name the gas released wen group 1 react with water.</h3>
<h3>This is the answer of your question. </h3>
Due to common ion effect, addition of 1.0mL of 4MNaCl will cause some of the Cu+ and Cl− ions combine to form CuCl(s) because the Ksp will be lower than 1.6×10−7.
<h3>What is solubility product?</h3>
The term solubility product refers to the equilibrium constant that is set up when an ionic substance dissolve in water. Since the solution already contains chloride ions, addition of more chloride ions from NaCl will cause more CuCl(s) to separate from solution.
Hence, when 1.0mL of 4MNaCl is added to the solution, some of the Cu+ and Cl− ions combine to form CuCl(s) because the Ksp will be lower than 1.6×10−7.

Answer:
<em>Each substance on the left side of the arrow in a chemical equation is a </em><u>reactant.</u>
Explanation:
The chemical changes (chemical reactions) are represented by <em>chemical equations.</em>
The chemical equations show the starting substances and the final substances.
The starting substances of the reaction are the reactants.
A single <em>arrow</em> is used to indicate the direction of the reaction, the <em>reactants </em>are placed <em>on the left side</em> of the equation, and the products appear on the right side.
This sketch shows that:
reactants yield products
general form A + B → C + D
example Na + Cl → NaCl
Conservation of mass is the underlying principle of balancing equation. When we balance equation, this means that we acknowledge that before and after the chemical reaction, the elements are conserved. To balance the chemical equation, we add coefficients before each reactant and product. Here are the following answers:
Reaction 1:
<span>2Al
3ZnCl2
3Zn
2AlCl3
Reaction 2:
