The combustion reaction of propane would be expressed as:

C3H8 + 5O2 = 3CO2 + 4H2O

To determine the mass of water that is produced from the given amount of propane, we use the mass of propane and the relation of the substances from the balanced reaction. We do as follows:

moles propane = 22 g C3H8 ( 1 mol / 44.1 g ) = 0.50 mol C3H8
moles H2O = 0.50 mol C3H8 ( 4 mol H2O / 1 mol C3H8) = 2 mol H2O
mass H2O = 2 mol H2O ( 18.02 g / 1 mol ) = 36.04 g H2O

Therefore, the mass of water that is produced from 22 grams of propane would be 36.04 g.

Justify the statement, "nuclear energy is harmful as well as useful."​
Olenka [21]

Nuclear energy is harmful because it releases of harmful ionizing radiation and has been employed in the production of atomic bombs and hydrogen bombs.

Nuclear energy is beneficial in that it produces vast amount of energy for domestic and industrial purposes.

<h3>What is nuclear energy?</h3>

Nuclear energy refers to the energy which is produced as a result of the changes that occur in the nucleus of atoms of elements.

Nuclear energy produces the largest amount of energy when compared to other forms of energy sources.

Nuclear energy is produced by two types of nuclear reactions:

  • Nuclear fission and Nuclear fusion

Nuclear energy is harmful in that it results in the release of harmful ionizing radiation which damages cells and tissues of living organisms.

Nuclear energy is also harmful because nuclear energy has been employed in the production of atomic bombs and hydrogen bombs.

On the other hand, nuclear energy is beneficial in that it produces vast amount of energy which can be used for domestic and industrial purposes. It also produces fewer wastes that damage the environment compared to fossil fuels.

In conclusion, nuclear energy is both beneficial and harmful.
