Answer: option B.olive oil.Explanation.The general rule of thumb when you analyze the ability of a solvent to dissolve a solute is that lke dissolves like.
That means:
1) polar solvents dissolve ionic or polar solutes
2) Non-polar solvents dissolve non-polar solutes
3) Non-polar solvents do not dissolve polar and ionic solutes
4) Polar solvents do not dissolve non-polar solutes.
There are exceptions, but the rule is applicable in here.

A. table salt: it is NaCl, a ionic compound, so the water which is a polar solvent will dissolve the table salt.
B. Olive oil: the oils are non-polar organic compounds, so it will not be dissolved in a polar solvent.
C. Vinegar: vinegar is acetic acid, which is a polar organic compound, so it will be dissolved in water.
D. Sugar: sugar (sucrose) is a polar organic compound, so it will get dissovled in water.</span>
The balanced chemical reaction is written as:
<span>Zn + 2AgNO3 = Zn(NO3)2 + 2Ag
To determine the grams of silver metal that is being produced, it is important to first determine which is the limiting reactant and the excess reactant from the given initial amounts. We do as follows:
4.35 g Zn ( 1 mol / 65.38 g ) ( 2 mol AgNO3 / 1 mol Zn ) = 0.1331 mol AgNO3 needed
35.8 g AgNO3 ( 1 mol / 169.87 g ) ( 1 mol Zn / 2 mol AgNO3 ) = 0.1054 mol Zn needed
Therefore, the limiting reactant would be the zinc metal since it would be consumed completely in the reaction. The excess amount of AgNO3 would be:
0.2107 mol AgNO3 - 0.1331 mol AgNO3 = 0.0776 mol AgNO3 left ( 169.87 g / 1 mol ) = 13.19 g AgNO3 left
0.0665 mol Zn ( 2 mol Ag / 1 mol Zn) ( 107.9 g / 1 mol) = 14.3581 g Ag produced</span>

hope this helped, please make me brainliest
A) 2H₂(g) + O₂(g) → 2H₂O(l) + 285.83 kJ
Exothermic
B) 2Mg + O₂ → 2MgO + 1200kJ
Exothermic
