Which of the answer choices correctly explains how the law of conservation of energy is fulfilled during an exothermic reaction? in an exothermic reaction, the products have higher potential energy than the reactants, so energy is absorbed from the surroundings during the reaction. in an exothermic reaction, the products have less potential energy than the reactants, so energy is released into the surroundings during the reaction. in an exothermic reaction, the products have less potential energy than the reactants, so energy is destroyed during the reaction. in an exothermic reaction, the products have higher potential energy than the reactants, so energy is created during the reaction

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.

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?
