Question

complete the equation. Na + H2-->

Answer 1

NaH2

Answer 2

Thank you ^_^

Answer 3

Na + H2O===>NaOH + H2

There's one Na on the left and right, one O on the left and right but there's 2 H on the left and 3 H on the right so you need to make the H on left and right equal.

Na + 2H2O===>2NaOH + H2

Now the H on each side is equal because there's 4 H on the left and 4 H on the right but Now there's 1 Na on the left and 2 Na on the right so that's not balanced. You need to now balance Na.

2Na + 2H2O--->2NaOH + H2

Now there's 2 Na on the left and 2 Na on the right, 4 H on the left and 4 H on the right, 2 O on the left and 2 O on the right so it's balanced.

2Na + 2H2O--->2NaOH + H2

(I wasn't sure whether you wanted the equation balanced or not, but hope this helps)

Answer 4

Actually... it was NaH x/

Answer 5

[AI-generated answer — Explain Bot]

To complete the equation, you need to determine the products that are formed when sodium (Na) reacts with hydrogen gas (H2). In this case, sodium is a metal and hydrogen is a non-metal. When an active metal like sodium reacts with a non-metal like hydrogen, they undergo a single displacement reaction and form an ionic compound.

The reaction can be written as follows:

2Na + 2H2 -> 2NaH

By balancing the equation, we can see that 2 atoms of sodium combine with 2 molecules of hydrogen gas to form 2 molecules of sodium hydride (NaH).
