Answer:

C) 4moles

Explanation:

Let's consider the following balanced equation.

2 H₂S(g) + 3 O₂(g) → 2 SO₂(g) + 2 H₂O(g)

The molar ratio of O₂(g) to SO₂(g) is 3:2. The moles of SO₂(g) produced from the reaction of 6 moles of O₂(g) are:

6 mol O₂(g) × (2 mol SO₂(g)/ 3 mol O₂(g)) = 4 mol SO₂(g)

When 6 moles of O₂(g) react with more than enough H₂S(g), 4 moles of SO₂(g) are produced.

The balanced equation is expressed:

<span>H2S + 3/2O2 --> SO2 + H2O
</span>
We are given the amount of O2 to be used in the reaction. This will be the starting point for our calculations. We do as follows:

6 mol O2 ( 1 mol SO2 / 3/2 mol O2 ) = 4 moles SO2 produced

Hope this answers the question. Have a nice day.

Answer:

Option C. hydroxide ions (OH-).

Explanation:

A base is a substance which dissolves in water to produce hydroxide ion (OH-) as the only negative ion. It therefore means that a base contains more hydroxide ions (OH-).

<span>While driving your rental car on your trip to Europe, you find that you are getting 9.7 kilometers per liter of gasoline. We know that 1 mile is equal to 1.609 kilometers. So divide 9.7 kilometers by 1.609 kilometrs/mile and you will get 6.03 miles per gasoline</span>

Answer:

d. add another d-cell to the circuit

Explanation:

To make the electromagnet pick something, the student should add another d-cell to the circuit.

Simply, the electromagnet set up is generating very weak magnetic fields.

To produce an electromagnet, there must be an interaction between electric fields an conductor.
As the wire turns around in the vicinity of the electric field, it induces magnetism.
The number of turns of wire here is pretty considerable.
But the electric field is very weak.
Additional d-cell in the circuit will circumvent this problem
