Zinc metal reacts with hydrochloric acid to produce zinc chloride and hydrogen gas as seen in the chemical equations below: Zn(s) + 2HCl(aq) === ZnCl2(aq) + H2(g)

What type of equation is described above?

F. Double Replacement

G. Single Replacement

H. Decomposition

J. Synthesis

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
