Sorry It isnt clear so hard to see
<span>the molecular weight of acetic acid is </span>60.05 g/mol
Answer:
True
Explanation:
I think it’s true because the empirical formula of a compound is actually the simplest formula that shows the numerical relationship of the elements in the compound.
hop that helps!
The total reaction energy calculated by reactant bond energy - product
bond energy
The reactant bond energy is usually higher than that of the product bond
energy. This is as a result of the bonds in the product having higher bond
energy than the reactants.
<h3>What is Total reaction energy?</h3>
The total reaction energy is therefore calculated by subtracting the product
bond energy from the reactant bond energy so as to know the net energy
which was used in the reaction.

For reaction a, the mole number of gas increase from 2 to 4. So the entropy will increase, ΔS>0. For b, the gas will change to solid, so the entropy decrease, ΔS<0.
