Answer:

C. One mole of water was produced from this reaction.

Explanation:

  • From the balanced equation:

<em>2H₂ + O₂ → 2H₂O,</em>

It is clear that 2 mol of H₂ react with 1 mol of O₂ to produce 2 mol of H₂O.

  • So, if one mole of hydrogen was used in this reaction:

1/2 mol of O₂ was used in the reaction, and

1 mol of water was produced from this reaction.

  • So, the correct statement is:

<em>C. One mole of water was produced from this reaction. </em>

Answer:

The correct answer is option C.

Explanation:

2H_2+O_2\rightarrow 2H_2O

If 1 mole of hydrogen is used. For that divide the whole equation with '2'.

\frac{2}{2}H_2+\frac{1}{2}O_2\rightarrow \frac{2}{2}H_2O

H_2+\frac{1}{2}O_2\rightarrow H_2O

When 1 mole of hydrogen reacts with half mole of oxygen it gives 1 mol of water.

So, from the given options the correct answer is option C.

Select the missing words to complete the definition of buffer capacity. Buffer capacity is the _____________ of acid or base a b
horsena [70]

Answer:

amount, pH value.

Explanation:

The buffer range is the pH range in which the buffer performs optimally, i.e., neutralizes even when a strong acid or base is introduced to it and resists any major change in its pH value.

The buffer capacity is the amount of acid or base that can be added before the pH of the buffer solution changes significantly.

Thus, the final statement becomes,

Buffer capacity is the amount of acid or base a buffer can handle before pushing the pH value outside of the buffer range.
