Heat of fusion: Hf = 334 J/g, Q = m. Hf Heat of vaporization: Hv = 2260 J/g, Q = m. Hv
2.1 J/g˚C Heat capacity (S) of solid water Q = m. S. ΔT
2.03 J/g˚C Heat capacity (S) of water vapor Q = m. S. ΔT
4.18 J/g˚C Heat capacity (S) of liquid water Q = m. S. ΔT

Which part of earth’s surface receives the most direct rays from the sun? a) equator b) ocean c) poles d) mountains

Plzz a sample of table sugar (sucrose, c12h22o11) has a mass of 7.801 g. ● a) calculate the number of moles of c12h22o11 in the sample b) calculate the number of moles of each element in c12h22o11 (number of moles of c, number of moles of h & number of moles of o) in the sample. (use your answer from part a as your starting point.) show your work and highlight your final answer. calculate the number of atoms of each element in c12h22o11 (number of atoms of c, number of atoms of h & number of atoms of o) in the sample. (use your answers from part b as your starting for each element.) show your work and highlight your final answer.

The dashed segment of the plotted experiment in the graph in the lesson is called an: interpolation extrapolation extension assumption
