Answer:
765.0 grams CuS
Explanation:
The limiting reagent is the reactant which completely reacts before the other reactant(s) is used up. When 9.0 moles Na₂S and 8.0 moles CuSO₄ react, it appears that CuSO₄ is the limiting reagent. You can tell because it results in the production of less product.
You can determine the mass of CuS by multiplying the moles by the molar mass. It is important to arrange the ratio in a way that allows for the cancellation of units.
Molar Mass (CuS): 95.62 g/mol
8.0 moles CuS 95.62 g
------------------------- x ----------------------- = 765.0 grams CuS
1 mole
During a combustion reaction the carbon in a hydrocarbon compound is paired with Oxygen (O2) in the air to form Carbon-Dioxide (CO2), whilst the Hydrogen too pairs with Oxygen to form water vapour (H2O). Heat is also produced during this reaction.

Answer:
Pyruvate, FAD, Acetyl CoA, Fumarate, Oxaloacetate
Explanation:
In the first half of the citric acid cycle pyruvate is oxidized,yielding a pair of electrons that reduce a molecule of NAD to NADH .Succinate is oxidized to fumarate using FAD as electron acceptor.A 2 carbon group from acetyl CoA enters the cycle.A second oxidation produces fumarate and 2 electrons.Malate is oxidized yielding a 4 carbon molecule of oxaloacetate and two electrons.
