When a solution of LiC2H3O2 reacts with a solution of MgSO4, what is the net ionic equation? No reaction Mg+2 (aq) + C2H3O2- (aq) → Mg(C2H3O2)2 (s) Mg+2 (aq) + 2C2H3O2- (aq) → Mg(C2H3O2)2 (s) 2Li+ (aq) + SO4-2 (aq) → Li2SO4 (s)

Answered by answersmine AT 22/10/2019 – 02:56 AM I think the correct answer would be the first option. When a solution of LiC2H3O2 is mixed  with a solution of MgSO4, no reaction would be observed from the mixture. This is because magnesium cannot replace lithium from the acetate compound. Lithium …

Choose the ionic compound from the following choices A)Cesium BromideB)Nitrogen Tirfluoride C)Soduim Chloride D)Carbon Dioxide

The best way to figure out ionic compounds is to simply look at where each element is on the periodic table. Ionic compounds tend to be on opposite sides of the periodic table.This is because a compound is ionic if one element gives up electrons and one receives electrons. Because …

Why is water an excellent solvent for most ionic compounds and polar covalent molecules but not for non-polar compounds? A) Water is a polar molecule. B) Water has a charge like an ion. C) Water is a deionizing substance. D) Water molecules have an unusually high kinetic energy in the liquid state.

A)Water is a polar molecule. When talking about solubility, the rule that “like dissolves like” is usually correct. This means that polar substances are soluble in other polar substances. This occurs because the opposite partially charged ends of different polar molecules are attracted to each other. Similarly, the partially charged ends …
