Consider the reaction below. 2H2 + O2 mc015-1.jpg 2H2O How many moles of water are produced from 13.35 mol of oxygen?
Leokris [45]

Answer: 26.7 moles

Explanation: 2H_2+O_2\rightarrow 2H_2O

As can be seen from the balanced chemical equation 2 moles of hydrogen combine with 1 mole of oxygen to give two moles of water.

1 mole of oxygen give = 2 moles of water.

Thus 13.35 moles of oxygen give=\frac{2}{1}\times 13.35=26.7moles of water.

Aleonysh [2.5K]

We usually expess solubility as the maximum number of grams of of a solute that will dissolve in 100 g of solvent.

For example, at 20 °C, the solubility of <em>sodium chloride</em> is <em>35.89 g/100 g water</em>.

What mass of hydrogen will be produced by the reaction of 67.3 g of tin with excess water according to the following reaction?
Crank

Answer:

Mass of hydrogen produced =2.28 g

Explanation:

Given data:

Mass of tin = 67.3 g

Mass of hydrogen produced = ?

Solution:

Chemical equation:

Sn + 2H₂O    → SnO₂+ 2H₂

Number of moles of Sn:

Number of moles = mass/ molar mass

Number of moles = 67.3 g/ 118.71 g/mol

Number of moles = 0.57 mol

Now we will compare the moles of tin with hydrogen from balance chemical equation.

                             Sn             :               H₂

                              1               :                2

                          0.57             :               2×0.57 = 1.14

Mass of hydrogen:

Mass = number of moles ×molar mass

Mass = 1.14 mol × 2 g/mol

Mass = 2.28 g
