If the typical percent yield of SO2 from the chemical reaction shown below is 75%, how much CS2 should be used in a reaction to ensure that a minimum of 15.0 g SO2 is produced?

11.875g of CS2

Explanation:

First, we try and get the reaction being talked about as the question doesn’t seem complete. From the question, we can see that that CS2 is used in the production of SO2. So let’s find this reaction!

Yes, the probable reaction is below;

CS2 + CO2 → 3C + 2 SO2

Carbon sulphide is reacting with carbon iv oxide to yield elemental solid carbon and sulphur iv oxide.

Let’s proceed to answer the question now!

Since 15.0g of SO2 is to be produced, with a percentage yield of 75%, the theoretical yield of SO2 will be;

15 * 100/75 = 20g

We can convert this value to moles by using the molar mass of SO2. The Molar mass of SO2 is 32 + 2(16) = 64g/mol

The number of moles of SO2 is thus 20/64 = 0.3125moles

We now proceed to get the number of moles of CS2.

From the reaction,

1 mole CS2 yielded 2 moles SO2

x mole CS2 will yield 0.3125 moles SO2

This x = 0.3125/2 = 0.15625 mole CS2

We then use the molar mass of CS2 to get the actual amount in grammes

The molar mass of CS2 is 12 + 32(2) = 12 + 64 = 76g/mol

The mass is thus 76 * 0.15625 = 11.875g

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
