Answer:

3 Litres.

Explanation:

The balance equation of reaction is written in equation (1) below;

4H2 (g) + CS2(g) -------------> CH4 (g) + 2H2S (g) ------------------------------(1).

(From the balanced equation above) one mole of methane, CH4 and two moles of Hydrogen Sulphide, H2S are being produced when one mole of carbon Sulphide, CS2 reacts with 4 moles of Hydrogen gas.

(Parameters given from the question): we have 36 litres of Hydrogen, H2 gas and 12 litres of carbon Sulphide, CS2 gas.

Therefore, 36 Litres of H2 would react completely with; 36 litres/ 4.

= 9 Litres of Carbon Sulphide.

LIMITING REAGENT: (The reagent that is totally consumed). Hydrogen gas, H2 is the limiting reactant since we have 12 litres of Carbon Sulphide, CS2.

EXCESS REAGENT: Carbon Sulphide.

Amount remaining= 12 Litres of CS2 - 9 litres that was reacted.

= 3 Litres.

Why did most of the alpha particles go straight through the gold foil in Rutherford's experiment?
andre [41]

Answer:

The fact that most alpha particles went straight through the foil is because the atom is mostly empty space.

Those that passed straight through did so because they didn't encounter any nuclei.

While you are using a battery, the cell reaction is going a) forward, b) backward, c) at equilibrium, d) TEXASIN all possible
polet [3.4K]

Answer:Cell reaction is going forward.

Explanation:

For any chemical reaction to be spontaneous or to move in forward direction the ΔG ,the Gibbs free energy must be negative.

The cell potential of a battery is positive for a spontaneous reaction, so for a battery to give output its cell potential must be positive.

Thermodynamics and electro-chemistry are related in the following manner:

ΔG=-nFE

n=number of electrons involved

F=Faradays constant

E=cell pottential of battery

so from the above equation ΔG would only be negative when E cell that is the cell potential is positive.

For a battery which is being used its cell potential is positive and hence the ΔG would be negative. So the cell reaction occurring would be in forward direction as ΔG is negative.

when the cell potential Ecell is 0 then ΔG is also zero then the reaction occurring in battery would be at equilibrium.

When the cell potential Ecell is - then ΔG is positive and the reaction would be occurring backwards.
