Explanation:

2Al⁰(s) + 3CuSO₄(aq) => Al₂(SO₄)₃(aq) + 3 Cu(s)

Did you know? ...

All chemical reactions are balanced such that the ∑ atomic masses of reactant elements = ∑ atomic masses of the product elements and is referred to as the 'Law of Mass Balance'.When a chemical equation is balanced such that coefficients are the lowest whole number ratios it is referred to as the 'standard equation' and the physical conditions are assumed to be at standard temperature-pressure conditions, or STP (0°C, 1atm). The coefficients represent 'mole' values of each substance where the mole is the mass of substance containing 1 Avogadro's Number (N₀) of particles of that substance. That is ...

1 mole = 1 N₀ = 6.023 x 10²³ particles = 1 formula weight

Also, it is assumed that a chemical equation containing gas phase components such as 3H₂(g) + N₂(g) => 2NH₃(g) is at STP conditions and the gas volumes in Liters are equal to coefficient x 22.4L. That is,

Vol H₂(g) = 3 moles x 22.4 L/mole = 67.2 Liters H₂(g)

Vol N₂(g) = 1 moles x 22.4 L/mole = 22.4 Liters N₂(g)

Vol NH₃(g) = 2 moles x 22.4 L/mole = 44.8 Liters NH₃(g)

The items that can be calculated from a chemical equation are

moles => coefficient values

equation masses => coefficient x formula wt. (grams)

particle numbers => coefficient x Avogadro's No. (=6.023 x 10²³)

gas volumes => coefficient x 22.4 Liters

molar energy values => Equation heat of rxn/coefficient

Yeah, I get carried away at times. Hope this will be useful. :-)

Answer from: Quest

Answer:

a. energy is absorbed in the reaction.

explanation:

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.
