Answer: 90
Explanation: Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.

Answer: <span>Chlorine is losing electrons and being oxidized.
Justification:
1) Chlorine is losing electrons
As you se the side of the products shwo two electrons, that means that those electons were lost by the reactants. Given that the only reactant is chlorine, it is releasing or losing those electrons.
2) Chlorine is being oxidized.
The substance that loses electrons and, hence, increases its oxidation number, is the substance being oxidized.
In this case Cl (-) in the side of the reactants has oxidation state (1-), while Cl2 in the side of the products has oxidation state 0. This shows that the oxidation state of chlorine increased, meaning that it is being oxidized.

That would be exothermic. Exothermic reactions are processes that release energy, usually in the form of heat or light. Energy is released because the total energy of the products is less than the total energy of the reactants.
<span>When silver nitrate reacts with sodium chloride, it produces silver chloride and sodium nitrate. The chemical reactions contains a one to one ratio of each compound on the reactant side and the products side.
In order to determine the correct answer, we must first convert the 25.0 milliliters to moles using:
moles = concentration * volume.
25 ml = 0.025 L
Moles of both reactants = 0.25 * 1 = 0.025
Now we have to calculate the mass of AgCl which is found by adding the atomic weight of silver and chlorine. The mass of AgCl is 143.3 g/mol. Multiplying 143.3 g/mol by 0.025 moles results in a mass of 3.58 grams of AgCl being produced.</span>
