Answer:
When hydrochloric acid and zinc are combined, they create hydrogen gas and zinc chloride, which is a salt.
Explanation:
<h2>It means that there are Z positive nuclear charges, and this determines the identity of the element. If the element is neutral, this means that there are precisely Z electrons, and the overall electronic charge is −Z . And thus the net ELECTRIC charge of the ATOM is Z+(−Z)=0 , i.e. zero </h2>
Answer: What type of chemical reaction is rusting of iron?
Rust is formed when iron reacts with oxygen in moist air. The following chemical equation represents the reaction: 4Fe + 3O2 → 2Fe2O3. Water is necessary for the oxidation reaction to occur and to facilitate transport of the electrons.
Answer:
See the attached file for the structure.

Answer:
A) 12 mol H2O.
Explanation:
Hello,
In this case, for the given reaction:

We notice that oxygen is in a 7:6 molar relationship with water, for that reason, the resulting moles of water turn out:

Thus, the answer is A) 12 mol H2O.
Best regards.
