Use the half-reactions of the reaction to answer the questions. Reduction half-reaction: How many electrons does each gold atom gain? How many electrons does each iodine atom lose? What is the total number of electrons that are moved in the oxidation-reduction reaction? Complete the final balanced equation based on the half-reactions. Au(OH)3+ HI Right arrow. Au + 3 I2 + H2O

Heat is the total potential energy of a substance that can be transferred. true false

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?

What type of reaction is this equation c2h5s + o2 > co2 + h2o + so2
