Calculate ∆H for the reaction CH4 (g) + NH3 (g) → HCN (g) + 3 H2 (g), from the reactions.
N2 (g) + 3 H2 (g) → 2 NH3 (g) ∆H = -91.8 kJ
C (s, graphite) + 2 H2 (g) → CH4 (g) ∆H = -74.9 kJ/mole
H2 (g) + 2 C (s, graphite) + N2 (g) → 2 HCN (g) ∆H = +270.3 kJ
above what value of inside diameter will 10% of the piston rings fall?
A manufacturer of tires claim that their tire has a mean life of at least 50,000kms. A random sample of 28 of these tires is tested and the sample mean is 33,000kms. Assume that the population standard deviation is 3,000kms and the lives of the tires are approximately normally distributed.
