Answer:
Nonrenewable resources are natural resources that are not naturally replenished once they have been used. Nonrenewable resources can be used up completely or consumed to such a degree that they become economically inaccessible
Explanation:
A nonrenewable resource is a resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption. Most fossil fuels, such as oil, natural gas, and coal are considered nonrenewable resources, as their use is not sustainable because their formation takes billions of years.
Based on the reactants and products,
- The molecular equation of the reaction is: Al(NO3)3 + 3 KOH ---> Al(OH)3 + NaNO3
- The complete ionic equation of the reaction is: Al3+ 3NO3- + 3 K+ 3OH- ---> Al(OH)3(s) + 3 Na+ 3 NO3+
- The net ionic equation of the reaction is:Al3+ 3OH- ---> Al(OH)3(s)
- The spectator ions are: Na+ and NO3+
<h3>What is a precipitate?</h3>
A precipitate is a solid product formed in when two solutions of salts react by double replacement.
The molecular equation of the reaction of Al(NO3)3 solution with a KOH solution is:
Al(NO3)3 + 3 KOH ---> Al(OH)3 + NaNO3
The complete ionic equation of the reaction of Al(NO3)3 solution with a KOH solution is:
Al3+ 3NO3- + 3 K+ 3OH- ---> Al(OH)3(s) + 3 Na+ 3 NO3+
The net ionic equation of the reaction of Al(NO3)3 solution with a KOH solution is:
- Al3+ 3OH- ---> Al(OH)3(s)

Dependent variables have to be in the experiment for it to work
independent variables do not.
Answer:
H₂O = 3.56 moles
MgCl₂ = 1.78 moles
Explanation:
Given data:
Moles of HCl = 3.56 mol
Moles of water produced = ?
Moles of MgCl₂ produced = ?
Solution:
Chemical equation:
2HCl + Mg(OH)₂ → MgCl₂ + 2H₂O
Now we will compare the moles of HCl with water and magnesium chloride.
HCl : MgCl₂
2 : 1
3.56 : 1/2×3.56 = 1.78 mol
HCl : H₂O
2 : 2
3.56 : 3.56 mol
