Answer 1

To determine how many water molecules are produced in the reaction between hydrogen and oxygen, we can use the balanced chemical equation provided:

\[ 6H_2 + 3O_2 → ?H_2O \]

In this reaction, to find how many water molecules are produced, we can follow the coefficients. For each 6 molecules of hydrogen gas (H2), 3 molecules of oxygen gas (O2) will produce water (H2O).

From the balanced equation, for every 6 H2 and 3 O2, we can deduce the number of water (H2O) molecules produced. Generally, the balanced reaction is:

For every **2** H2 and **1** O2, **2** H2O are produced.

Thus, you can scale it up:
- 6 H2 + 3 O2 will produce **6 water (H2O) molecules**.

So the correct answer is:

**six**
