According to the kinetic-molecular theory, which sequence represents the relationship between pressure and volume of an ideal gas? A. more gas particles -> more collisions -> higher pressure
B. smaller volume -> crowded particles -> more collisions -> higher pressure
C. more gas particles -> more kinetic energy -> more volume -> higher pressure
D. smaller volume -> crowded particles -> less collisions -> lower pressure

Rank the following four acids in order of increasing bronsted acidity : h2f+ , ch3oh, (ch3)2oh+ , ch3sh2+

The combustion of methane, ch4, releases 890.4kj/mol. that is, when one mole of methane is burned,890.4 kj are given off to the surroundings. this meansthat the products have 890.4 kj less than the reactants.thus, ah for the reaction = - 890.4 kj. a negative symbolforah indicates an exothermic reaction.ch (g) + 20 (g)> co2 (g) + 2 h0 (1); ah = - 890.4 kga) how much energy is given off when 2.00 mol of ch,are burned? b) how much energy is released when 22.4g of ch. areburned?
