In the chemical plating experiment zinc powder is dissolved in a hot NaOH solution to form

sodium zincate according to the following reacton:
Zn(s) + 2NaOH(aq) Na2ZnO2(aq) + H2(g)
Answer true or false for each of the following statements regarding the reaction above.

Zn(s) is reduced to form Zn+.

A. true
B. false

Na+ is oxidized to form Na2+.

A. true
B. false

Zn(s) is oxidized to form Zn2+.

A. true
B. false

For every mole of Zn(s), two moles of sodium hydroxide are used .

A. true
B. false

I think the answers are
1. True
2. False
3. false
4. True

Can you check if these are right please?
thank you

Look at 1 and 3.

Zn has oxidation state of zero on the left and +2 on the right. So it lost electrons, right? Loss of electrons is oxidation. Remember, Leo the lion goes Grrr. LEO--loss electrons oxidation.

Let's go through each statement to check if your answers are correct.

1. "Zn(s) is reduced to form Zn+."
In the balanced chemical equation provided, we see that Zn(s) is not converted to Zn+ directly. Instead, it is oxidized to Zn2+. The correct answer is:
B. False

2. "Na+ is oxidized to form Na2+."
In the balanced chemical equation, there is no mention of Na+ being oxidized to Na2+. Therefore, the statement is false. The correct answer is:
B. False

3. "Zn(s) is oxidized to form Zn2+."
As mentioned earlier, in the given reaction, Zn(s) is oxidized to Zn2+. So, the statement is true. The correct answer is:
A. True

4. "For every mole of Zn(s), two moles of sodium hydroxide are used."
According to the balanced equation, 1 mole of Zn(s) reacts with 2 moles of NaOH(aq). Therefore, the statement is true. The correct answer is:
A. True

So, the correct answers are:
1. B. False
2. B. False
3. A. True
4. A. True

You were correct on statement 4, but statements 1, 2, and 3 are incorrect.
