Answer: C a substance that can dissolve other substances
Explanation: A solvent is a substance that dissolves a solute, resulting in a solution. A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid. The quantity of solute that can dissolve in a specific volume of solvent varies with temperature

Answer:
[Y₂] = 31.25M
Explanation:
Based on the chemical reaction:
2X(g) + Y2(g) ⇌ 2XY(s)
We must define the equilibrium constant, K as:
K = 20 = 1 / [X]²[Y₂]
<em>Where</em> [X] and [Y₂]<em> are the equilibrium concentrations of each gas.</em>
<em />
If [X] = 4.0x10⁻²M:
20 = 1 / [4.0x10⁻²M]²[Y₂]
0.032 = 1 / [Y₂]
<h3>[Y₂] = 31.25M</h3>
Answer:
Generally, observed behavior that can be formulated into a statement, sometimes mathematical in nature, is called a natural law- D.
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.
