option a best explain what thermal energy is
Molar mass of C3H8 = C 3 (12.01 g/mol) = 36.03 (g/mol)
H 8 (1.008 g/mol) = 8.064 (g/mol)
44.09 (g/mol)
74.6 g propane x 1 mole propane x 6.022 x 10
23
molecules
44.09 g propane 1 mole propane
= 1.02 x 10
24 molecules propane
Answer:
Explanation:
Heat of vaporization is the amount of heat required to convert 1 mole of liquid substance to its vapor form.
Given :
Amount of heat required for 1 mol of water = 40.7 kJ/mol
According to avogadro's law, 1 mole of every substance occupies 22.4 L at NTP, weighs equal to the molecular mass and contains avogadro's number of particles.
1 mole of weighs = 18.02 g
Thus we can say:
18.02 g of requires heat = 40.7 kJ
Thus 5.6 g of requires heat = (1kJ=1000J)
Thus the energy required to completely vaporize 5.6 g of water at 100.°C is
Particle C is more likely to participate in the reaction than particle B.
