Question

How many atoms of H are there in 1 mole of CeHszOs?? a.) 12 b.) 7.2 x 10 c.) 1.99 x 1023 d.) 28 Bacon frying in a pan is an example of what type of heat transfer? a.) Baconation b.) Conduction c.) Convection d.) Radiation Rainwater turning to ice on a road is an example of what type of phase change? a.) Evaporation b.) Deposition c.) Freezing d.) Sublimation Ice forming on the walls of a freezer is an example of what type of phase chang a.) Evaporation b.) Deposition c.) Freezing d.) Sublimation

Explanation / Answer

1 mole of C6H12O6 contains 12 moles of H
no of H atoms = no of moles of H * 6.023*10^23
                  = 12*6.023*10^23
                  = 7.2276*10^24 H atoms
2. b. Conduction
3. c. freezing   ( liquid converted to solid is called freezing)
4. b. deposition
