The equation for enthalpy change (δh) at constant pressure (p) is δh = qp = δe + pδv, where qp is the heat lost or gained at constant pressure, δe is the change in the internal energy of the system, and δv is the change in volume (v2 − v1) of the system. a sample of gas is maintained at a constant pressure of 2.63 atm. after 617 j of thermal energy is applied to (and absorbed by) the gas, its internal energy has increased by 483 j. by how much has the volume of the gas changed? (include the sign of the value in your answer.)

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.
