An unknown amount of gold was being polished in a hot bath that had an initial temperature of 471 °C. This caused the gold to absorb 7640 J of
heat. After some time the water temperature was found to be 24 °C. Find
the unknown mass of the gold. Specific heat
Copper. 0.385 J/g x C
Aluminum. 0.902 J/g x C
Iron. 0.450 J/g x C
Gold. 0.129 J/g x C

A.132.5 g
B.2467.7 g
C.125.7 g
D.1725.8 g

Achemical equilibrium between gaseous reactants and products is shown. n2(g) + 3h2(g) ⇌ 2nh3(g) how will the reaction be affected if the pressure on the system is increased? it will shift toward the reactant side as there is lower pressure on the reactant side. it will shift toward the product side as there is higher pressure on the product side. it will shift toward the reactant side as there are a greater number of moles of gas on the reactant side. it will shift toward the product side as there are a fewer number of moles of gas on the product side.
