The volume of carbon dioxide that will be produced is 191.4 g.

Calculation:

The following is the balanced equation for the given reaction:

Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂(g),

It is obvious that when 1.0 mole of Fe2O3 reacts with 3.0 mole of CO, 2.0 mole of Fe and 3.0 mole of CO2 are produced.

Hence by using cross multiplication:

If 2.0 mol of Fe was produced with → 3.0 mol of CO₂, from stoichiometry.

Then how many moles of CO₂ are produced by 2.9 mol of Fe?

To find the answer we have a formula:

∴ The no. of moles of CO₂ produced = (3.0 mol)(2.9 mol)/(2.0 mol) = 4.35 mol.

∴ The mass of CO₂ produced = no. of moles x molar mass = (4.35 mol)(44.0 g/mol) = 191.4 g.

Tresset [83]

Answer:

The final pressure of the carbon dioxide gas will 11.84 atm.

Explanation:

Moles of carbonic acid = $\frac{60.0 g}{62 g/mol}=0.9677 mol$

$H_2CO_3(aq)\rightarrow H_2O(l) + CO_2(g)$

According to reaction, 1 mol of carbonic acid gives 1 mole of carbon dioxide gas.

Then 0.9677 moles of carbonic acid will give :

$\frac{1}{1}\times 0.9677 mol=0.09677 mol$ of carbon dioxide

Moles of carbon dioxide gas = n = 0.09677 mol

Volume of soda bottle = $V_1=2 L$

Pressure of the carbon dioxide gas = P

Temperature of the carbon dioxide gas = T = 298 K

$PV=nRT$ (ideal gas law)

$P=\frac{nRT}{V}=\frac{0.9677 mol\times 0.0821 atm L/mol K\times 298 K}{2 L}=11.84 atm$

The final pressure of the carbon dioxide gas will 11.84 atm.

Determine whether methylcyclohexane contains a chiral center. _____ How many different substituents do you count at atom

AveGali [126]

Answer:

methylcyclohexane does not possess a chiral center

Explanation:

A molecule is said to possess a chiral center if one or more of the atoms in the molecule is bonded to four different atoms or groups.

If we look at methylcyclohexane, none of the carbon atoms in the molecule is bonded to four different atoms or groups hence the molecule contains no chiral centers and will not exhibit optical isomerism.

So, methylcyclohexane has a plane of symmetry thus it is an achiral molecule.

In an aqueous solution of potassium chloride the solute is

Goryan [66]

Answer:

Potassium chloride

Explanation:

A solution is formed by a solvent and one or more solutes.

The solvent is the species that is in major proportion and usually defines the state of aggregation of the solution, while the solute/s is/are in minor proportion.

Also, water is known as the universal solvent, so in any solution containing water, it is considered as the solvent.

Then, in an aqueous solution of potassium chloride the solute is potassium chloride.
