Consider the redox reaction below. Zn(s) + 2HCl(aq)
→ ZnCl2(aq) + H2(g)
Which half reaction correctly describes the oxidation that is taking place?
Zn4*(s) + 2e (aq) — Zn(s)
2+
Zn(s) —>Zn2+ (aq) + 2e-
O 2H+ + 2e - →H2
H2+2e → 2H+

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

The image shows a process that releases nuclear energy which statement best identifies the process shown the process must be fusion because energy is released the process must be fusion because of have your nucleus formed a smaller nuclei the process must be fission because a large nucleus breaks into smaller nuclei the process must be fission because neutrons are formed

In 1901, thomas edison invented the nickel-iron battery. the following reaction takes place in the battery. fe(s) + 2 nio(oh)(s) + 2 h2o(l) fe(oh)2(s) + 2 ni(oh)2(aq) how many mole of fe(oh)2, is produced when 5.35 mol fe and 7.65 mol nio(oh) react?
