The balanced chemical equation that illustrates this reaction is:
<span>C2H4 + 3O2 --> 2CO2 + 2H2O
</span>
From the periodic table:
mass of carbon = 12 grams
mass of hydrogen = 1 gram
Therefore:
molar mass of C2H4 = 12(2) + 4(1) = 24 + 4 = 28 grams
number of moles = mass / molar mass
number of moles of C2H4 = 54.7 / 28 = 1.95 moles
From the balanced equation above:
3 moles of oxygen are required to react with one mole of C2H4, therefore, to know the number of moles required to react with 1.95 moles of C2H4, all you have to do is cross multiplication as follows:
number of oxygen moles = (1.95*3) / 1 = 5.85 moles
Answer:
the females make eggs and males make the sperm
Explanation:
A. radiation
Explanation:
The heat transfer mechanism that causes the surface of the earth to gain heat is by radiation.
Electromagnetic radiation is able to cause the heating of the surface by radiation.
Radiation is one of the methods of heat transfer the does not involve any particle.
The surface of the earth absorb some of the radiation and it causes them to warm up.
