Zinc + Sulphuric Acid ---> Zinc Sulphate + Hydrogen
Because Zinc Sulphate is a salt, it will always have Hydrogen.
Hope this helped :)

Explanation:
Hello there!
In this case, for these problem about the colligative property of freezing point depression, it is possible set up the following equation:
Whereas the van't Hoff's factor, i, is 2 since KCl is ionized in two ions (K+ and Cl-); and the molality (m) of the solution is computed by:
Thus, since the freezing point of water (ice) is 0°C, we obtain the following freezing point of the solution by plugging in:

Answer:
A
Explanation:
This is the only reaction where a element is displaced out of a solution and turn a soild, due to it been less reactive than the other causing its displacement The electrochemical series can be used as reference.
Answer:
beryllium is the answer.

For the answer to the question above,
322Joules of heat energy is added to the system (gold bar) while no work is done on the gold bar, this is an isochoric/isovolumetric process, thus
<span>ΔU = 322J + 0 </span>
<span>=322J </span>
<span>Therefore the internal energy increase by <u>322J
