Explanation:
First, balance the chemical reaction
C3H8 + 5O2 --> 4H2O + 3CO2
Using the mole ratio, we can multiply the moles of propane by 4 to find the moles of H2O.
5 × 4= 20
20 mol
Answer:
Calcium atoms have smaller radii than potassium atoms since calcium atoms have a greater nuclear charge. Each calcium atom will be closer to the delocalized electrons. Thus, the bonds in calcium will be stronger than that in potassium.
