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.

Pure research becomes ___ when scientists develop a hypothesis based on the data and try to solve a specific problem
Inessa05 [86]

Answer:

The answer is <u>applied research</u>

Explanation:

Pure research becomes <u>applied research</u> when scientists develop a hypothesis based on the data and try to solve a specific problem.

This is because the pure research try to understand, predict or explain the behavior of different phenomena <em>(the data)</em> while the applied research try to develop new technologies or methods (<em>hypothesis)</em> to take part, intervene and/or create changes on these phenomena and solve a <em>specific problem.</em>

For each reaction, find the value of ΔSo. Report the value with the appropriate sign. (a) 3 NO2(g) + H2O(l) → 2 HNO3(l) + NO(g)
aev [14]

Answer:

ΔS° = -268.13 J/K

Explanation:

Let's consider the following balanced equation.

3 NO₂(g) + H₂O(l) → 2 HNO₃(l) + NO(g)

We can calculate the standard entropy change of a reaction (ΔS°) using the following expression:

ΔS° = ∑np.Sp° - ∑nr.Sr°

where,

ni are the moles of reactants and products

Si are the standard molar entropies of reactants and products

ΔS° = [2 mol × S°(HNO₃(l)) + 1 mol × S°(NO(g))] - [3 mol × S°(NO₂(g)) + 1 mol × S°(H₂O(l))]

ΔS° = [2 mol × 155.6 J/K.mol + 1 mol × 210.76 J/K.mol] - [3 mol × 240.06 J/K.mol + 1 mol × 69.91 J/k.mol]

ΔS° = -268.13 J/K
