Answer:

16.4 mol

Explanation:

H₂SO₄ can be produced from FeS₂ in 3 steps:

Step 1: 4 FeS₂ + 11 O₂ → 2 Fe₂O₃ + 8 SO₂

Step 2: 2 SO₂ + O₂ → 2 SO₃

Step 3: SO₃ + H₂O → H₂SO₄

We can establish the following relations:

  • According to Step 1, the molar ratio of FeS₂ to SO₂ is 4:8.
  • According to Step 2, the molar ratio of SO₂ to SO₃ is 2:2.
  • According to Step 3, the molar ratio of SO₃ to H₂SO₄ is 1:1.

The moles of H₂SO₄ produced from 8.21 moles of FeS₂ are:

8.21molFeS_{2}.\frac{8molSO_{2}}{4molFeS_{2}} .\frac{2molSO_{3}}{2molSO_{2}} .\frac{1molH_{2}SO_{4}}{1molSO_{3}} =16.4molH_{2}SO_{4}

Well, if the coefficients are both 1, then you will make 8.21 moles.

See the equation is:

x moles= (8.21mol FeS₂)×(1 mole H₂SO₄ ÷ 1 mole FeS₂) = 8.21 moles H₂SO₄

So if you change the coefficients of the equation, your product will be a different number.

Example:
x moles= (8.21mol FeS₂)×(2 mole H₂SO₄ ÷ 1 mole FeS₂) = 16.4 moles H₂SO₄

I hope this helps you out!

In the forward reaction of this equilibrium, which substance acts as the Brønsted-Lowry base? H2S(aq)+CH3NH2(aq)⇋HS−(aq)+CH3NH+3
timama [110]
H2S donates a proton, therefore it is a Brønsted-Lowry base; CH3NH2 accepts a proton, so it’s a Brønsted-Lowry base.

Answer:

6.67 moles

Explanation:

Given that:-

Moles of hydrogen gas produced = 10.0 moles

According the reaction shown below:-

2Al + 6HCl\rightarrow 2AlCl_3 +3H_2

3 moles of hydrogen gas are produced when 2 moles of aluminium undergoes reaction.

Also,

1 mole of hydrogen gas are produced when \frac{2}{3} moles of aluminium undergoes reaction.

So,

10.0 moles of hydrogen gas are produced when \frac{2}{3}\times 10.0 moles of aluminium undergoes reaction.

<u>Moles of Al needed  = \frac{2}{3}\times 10.0 moles = 6.67 moles</u>

What is radioactive decay?
swat32

Answer:

Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles or photons.
