Suppose 5.00g of Zn metal is completely consumed in an HCl solution to produce zincil) choride (ZnCl2) and hydrogen gas (H2) according to the following reaction:
Zn(s) + 2HCl(aq) > ZnCl2(aq) + H2(g)
Part A
How many moles of ZnCl2 are produced?
moles =
Part B
How many grams of H2 are produced?
grams =

The oxidation half reaction for the given reaction is

Explanation:

Oxidation reaction is defined as the reaction in which a substance looses its electron. The oxidation state of the substance gets increased.

Reduction reaction is defined as the reaction in which a substance gains electrons. The oxidation state of the substance gets reduced.

For the given chemical equation:

Oxidation half reaction:

Reduction half reaction:

Zinc is getting oxidized and hydrogen is getting reduced.

Hence, the oxidation half reaction for the given reaction is

it would be d. henry moseley

hope this !

and sorry if i'm late. have a good rest of your day! : d

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
