<span>Propane is C3H8
The balanced equation is:
C3H8 + 5 O2 --> 3 CO2 + 4 H2O
From the balanced equation you can see that for each mole of C3H8 you obtain 4 moles of H2O.
moles H2O = 5.0 moles C3H8(4 moles H2O/1 mole C3H8) = 20 moles H2O formed
Use Avogadro's number to find the number of molecules.
molecules H2O = 20 moles H2O(6.02 x 10^23 molecules/1 mole) = 1.20 x 10^25 H2O molecules</span><span>

A pure crystalline substance is a substance with an almost perfect regular and periodic pattern in a solid state. This makes this type of substance a hard one compared to an amorphous substance which is soft because of the irregular pattern within.

Answer:
A. the burning of fossil fuels within the Sun
Explanation:
Answer:
C
Explanation:
Melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached. More heat then will convert the solid into a liquid with no temperature change.
