Answer:
Single Replacement; 2, 1, 1, 1
Explanation:
2HCl + Zn → H2 + ZnCl2
In a single replacement reaction, one specie is replaced by another specie in a chemical reaction.
If we look at the reaction above, zinc metal reacted with hydrochloric acid. The reaction proceeds in such a manner that zinc replaces hydrogen in hydrochloric acid. This is a single replacement reaction because only one chemical specie is displaced in the reaction.
Answer:
O Charles's law
.
Explanation:
Hello!
In this case, since the use of gas laws leads to a good comprehension of how gases behave towards volume, pressure and temperature, we can review that the Boyle's law explains the pressure-volume variation, the Dalton's law the partial pressure effect, the Gay-Lussac's law that of pressure and temperature and the Charles' that of temperature and volume at constant pressure; thus, the answer for the asked question is:
O Charles's law
