At 1023 k and 1 atm, a 3.00 gram sample of sno2(s) (gram-formula mass = 151 g/mol) reacts with hydrogen gas to produce tin and water, as shown in the balanced equation below: sno2 (s) + 2 h2 (g) > 2 h2o (g) + sn (l) determine the number of moles of sn(l) produced when 4.0 moles of h2(g) is completely consumed.

can you attach a picture of the lettuce? : )

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
