Be sure to answer all parts. write a balanced equation and kb expression for the following brønsted-lowry base in water: benzoate ion, c6h5coo−. include the states of all reactants and products in your equation. you do not need to include states in the equilibrium expression. balanced equation: ⇌ kb expression:

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?
