What mass of lp gas is necessary to heat 1.3 l of water from room temperature (25.0 ∘ c ) to boiling (100.0 ∘ c )? assume that, during heating, 16% of the heat emitted by the lp gas combustion goes to heat the water. the rest is lost as heat to the surroundings. express your answer using two significant figures. lp gas burns according to the following exothermic reaction: c3h8(g)+5o2(g)→3co2(g)+4h2o(g)δh∘rx n=−2044kj

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
