(a) Interpretation: The mass of sample of air in grams should be calculated which consist of one mole of entities. Concept introduction: Number of moles is equal to the ratio of given mass to the molar mass. The mathematical expression is given by: Number of moles = Given mass Molar mass Molar mass of the molecule is equal to the sum of the masses of atoms present in the molecule. Molecular formula is defined as the formula in which elements are present in actual numbers in a compound.

Solution Summary: The author explains that the mass of a sample of air in grams should be calculated.
A block of zinc has an initial temperature of 94.2 degrees celcius and is immererd in 105 g of water at 21.90 degrees celcius. At thermal equilibrium, the final temperature is 25.20 degrees celcius. What is the mass of the zinc block? Cs(Zn) = 0.390 J/gxdegrees celcius Cs(H2O) = 4.18 J/gx degrees celcus
Potential Energy (kJ)
1. Consider these three reactions as the elementary steps in the mechanism for a chemical reaction.
AH = -950 kJ
AH = 575 kJ
(i) Cl₂ (g) + Pt (s) 2C1 (g) + Pt (s)
Ea = 1550 kJ
(ii) Cl (g)+ CO (g) + Pt (s) → CICO (g) + Pt (s)
(iii) Cl (g) + CICO (g) → Cl₂CO (g)
Ea = 2240 kJ
Ea = 2350 kJ
AH = -825 kJ
