Stoichiometry A gas occupies a volume of 283 c.c at 10°C. If it is heated to 20°C at constant pressure, the new volume of the gas will be __________ c.c. 141.5 283 293 566 141.5 283 293 566 ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry Specific gravity on API scale is given by the relation(where, G = specific gravity at 15.5°C). °API = 145 - (145/G) °API = (141.5/G) - 131.5 °API = (140/G) - 130 °API = 200(G - 1) °API = 145 - (145/G) °API = (141.5/G) - 131.5 °API = (140/G) - 130 °API = 200(G - 1) ANSWER DOWNLOAD EXAMIANS APP
Stoichiometry The combustion equations of carbon and carbon monoxide are as follows: C + O₂ = CO₂, ΔH = - 394 kJ/kg . mole CO + 1/2 O₂ = CO₂, ΔH = - 284.5 kJ/kg. mole. The heat of formation of CO is __________ kJ/kg. mole. +109.5 +180 +100 -109.5 +109.5 +180 +100 -109.5 ANSWER DOWNLOAD EXAMIANS APP

Stoichiometry Heat of neutralisation of a strong acid and strong base is always a constant value, i.e., 57 KJ/Kg mole. This is because The strong base and strong acid reacts completely Only OH⁻ and H⁺ ions react in every case The strong base and strong acid reacts in aqueous solution The salt formed does not hydrolyse The strong base and strong acid reacts completely Only OH⁻ and H⁺ ions react in every case The strong base and strong acid reacts in aqueous solution The salt formed does not hydrolyse ANSWER DOWNLOAD EXAMIANS APP
