No plain water is involved but since the reaction is taking place in water SOLUTION the water is what is being evaporated therefore creating hydrogen (gas). Depending on the control variables you have (temp, pH, etc.), your reaction could either produce CI2, CIO-, or O2. Since it has such a high calcium concentration... it is probable that the Ca(OH)2 or whichever similar chemical used would then break out and cover the cathode, therefore resulting in H2 generating an electrode.

Answer:
Balancing chemical equation means making a number of atoms or molecules equal on both sides. In other words, this means that the number of atoms and molecules of each reacting element needs to be the same as the number of atoms and molecules of those elements in the product.
Our reaction is:
AlBr3 + K2SO4 -> KBr + Al2(SO4)3
and we need to balance it.
Since there are 3 molecules of SO4 in the product we need to put 3 before the reactant K2SO4. There are also 2 atoms of Al in the product, so we need to put 2 in front AlBr3. Now we have 6 atoms of K and Br on the left side, so we need to put 6 in front of KBr in the product.
So, our balanced equation will look like this:
2AlBr3 + 3K2SO4 -> 6KBr + Al2(SO4)3

When approaching this question, we need to consider what ethanol and water have in common. The only similarities between the two that come to my mind are the fact that they’re both clear. And they’re both liquids at room temperature.
Answer:
The answers to the questions are;
Part A, endothermic
Part B, above 100 °C
Part C below 100 °C
Part D, 100 °C.
Explanation:
Part A endothermic,
The vaporization of water requires the addition of the heat of vaporization for the given mass of water as well as the heat required to raise the water to the boiling point.
Part B, above 100 °C
The boiling or vaporization of water is a spontaneous process above the boiling point for water which is 100 °C point
Part C below 100 °C
It is a non-spontaneous process below the boiling point of water which is 100 °C
Part D, 100 °C
Water is in equilibrium with steam at 100 °C.
