Answer: Rubber source, temperature, thinkness, thread design, driving pattenrs, weather, etc.
Explanation: There are many variables. Here are a few I would include in a tire lifetime study:
1. Type of rubber, including source
2. Thickness of tire
3. Design of tire thread
4. Life as a function of average speed and road surface
5. Expected outside temperature and wet conditions
6. Driving conditions of speed and both acceleration and deceleration parameters (e.g., tire life when slamming on the brakes or accelerating quickly)
The unbalanced equation is one in which the moles of atoms are not equal on both sides of the reaction.
<h3>What is a balanced chemical equation?</h3>
A balanced chemical equation is one in wgich the moles of atoms in the reactants side is equal to the moles of atoms on the product side.
The given equations of reaction is not clearly stated.
Therefore, the unbalanced equation is one in which the moles of atoms are not equal on both sides of the reaction.

Answer: The given statement is false.
Explanation:
Precipitation reaction is defined as the chemical reaction in which two aqueous solution upon mixing together results in the formation of an insoluble solid.
For example, 
Here AgCl is present in solid state so, it is the precipitate.
But it is not necessarily true that two aqueous solutions will always result in the formation of a precipitate.
For example, 
Hence, we can conclude that the statement precipitation reactions always occur when two aqueous solutions are mixed, is false.
