If 1.50×105 J of energy is supplied to a flask of liquid oxygen at -183∘C, how much oxygen can evaporate? The heat of vaporization for oxygen is 210 kJ/kg.

Ametal with a large number of free flowing electrons most likely has good conductivity

There is no reason to think the results are biased or not conducted properly but you should not assume the results are correct just because they were done in a laboratory so the answer would be c. it is likely to be reliable because the results support the conclusion presented.

Ithink that the answer is b

In reversible reaction chemistry equilibrium is attained when the forward and reverse reactions are taking place at the same rate, thus, the concentrations of reactants and products remain the same. a reversible reaction is a chemical reaction where the reactants form products that, in turn, react together to give the reactants back. in irreversible reactions on the other hand, the reactants react to form the products, which cannot revert back into reactants.
