The correct classification of the solutes are as follows:
<span>hydroiodic acid hi = strong electrolyte
calcium hydroxide ca(oh)2 = weak electrolyte
hydrofluoric acid hf = weak electrolyte
methyl amine ch3nh2 = weak electrolyte
sodium bromide nabr = strong electrolyte
propanol c3h7oh = non electrolyte
sucrose c12h22o11 = non electrolyte
Strong electrolytes are substances that completely ionizes in aqueous solution while weak electrolytes are those that partially ionizes. Non electrolytes are substances that cannot conduct electric charge since there are no ions in the solution.</span>
Answer: add up to eight
Explanation: NaO as one bond as it takes only one and seven to make eight. Leaving NaO with three lone pairs
<u>Answer:</u> The unbalanced chemical equations are written below.
<u>Explanation:</u>
An unbalanced chemical equation is defined as the equation in which total number of individual atoms on the reactant side is not equal to the total number of individual atoms on the product side. These equations does not follow law of conservation of mass.
The chemical equation for the reaction of nitrogen gas and oxygen gas follows:

The product formed is nitrogen dioxide.
The chemical equation for the decomposition of dinitrogen pentaoxide follows:

The product formed is dinitrogen tetroxide and oxygen gas.
The chemical equation for the reaction of ozone to oxygen gas follows:

The product formed is oxygen gas.
The chemical equation for the reaction of chlorine and sodium iodide follows:

The product formed is sodium chloride and iodine gas
The chemical equation for the reaction of magnesium and oxygen gas follows:

The product formed is magnesium oxide
If it isn't using energy, it's called diffusion
