How many moles of sulfur will be needed to oxidize 3 moles of zinc to zinc sulfide
Ksenya-84 [330]

Answer : The number of moles of sulfur needed to oxidize will be, 3 moles

Solution : Given,

Moles of zinc = 3 moles

The balanced reaction will be,

Zn^{2+}+S^{2-}\rightarrow ZnS

By the stoichiometry, 1 mole of Zn^{2+} ion react with the 1 mole of S^{2-} to give 1 mole of zinc sulfide.

From the balanced reaction, we conclude that

As, 1 mole of zinc react with 1 mole of sulfur

So, 3 moles if zinc react with 3 moles of sulfur

Hence, the number of moles of sulfur needed to oxidize will be, 3 moles

If I add 475mL of water to 75.0mL of a 0.315M NaOH solution, what will the molarity of the diluted solution be?
pantera1 [17]
Answer is: <span>the molarity of the diluted solution 0,043 M.
</span>V(NaOH) = 75 mL ÷ 1000 mL/L = 0,075 L.
c(NaOH) = 0,315 M = 0,315 mol/L.
n(NaOH) = c(NaOH) · V(NaOH).
n(NaOH) = 0,075 L · 0,315 mol/L.
n(NaOH) = 0,023625 mol.
V(solution) = 0,475 L + 0,75 L.
c(solution) = 0,023625 mol ÷ 0,550 L.
c(solution) = 0,043 mol/L.

Under identical conditions, separate samples of O2 and an unknown gas were allowed to effuse through identical membranes simulta
Varvara68 [4.7K]

Answer:

identical conditions, separate samples of O2 and an unknown gas were allowed to effuse through identical membranes simultaneously. After a certain amount of time, it was found that 6.23 mL of O2 had passed through the membrane, but only 3.85 mL of of the unknown gas had passed through. What is the molar mass of the unknown gas
