Carbon can form large number of organic compounds why

Chemistry
1 answer:
Vinvika [58]3 years ago
8 0

Answer:

Carbon is the only element that can form so many different compounds because each carbon atom can form four chemical bonds to other atoms, and because the carbon atom is just the right, small size to fit in comfortably as parts of very large molecules.

Hydrogen peroxide is oxidized with permanganate solution to produce oxygen gas by the following reaction:
monitta

The percentage yield of the oxygen gas is 60%.

<h3>What is the limiting reactant?</h3>

The reaction equation is;

2H^+ + H2O2 + 2MnO4 -> 2MnO2 + 4H2O + 3O2

Number of moles of hydrogen peroxide = 30/1000 * 0.30 M = 9 * 10^-3 moles

Number of moles of  potassium permanganate = 30/1000 * 0.30 M = 9 * 10^-3 moles

Now;

1 mole of H2O2 reacts with 2 moles of permanganate

 9 * 10^-3 moles of H2O2 reacts with  9 * 10^-3 moles * 2 moles/1 mole  

= 1.8 * 10^-2 moles

Hence, permanganate is the limiting reactant

b) The theoretical yield of oxygen is;

2 moles of oxygen produced 3 moles of O2

9 * 10^-3 moles oxygen  produced 9 * 10^-3 moles *  3 moles/2 moles

= 0.0135 moles

If 1 mole of O2 occupies 22.4 L

0.0135 moles of O2 occupies 0.0135 moles * 22.4 L/ 1 mole

= 0.302 L or 302 mL

c) Percentage yield of oxygen = 178 mL/ 302 mL * 100/1

= 60%

What is the difference between a pure solvent and a solution? Do they have the same physical properties?
pychu [463]

Answer:

The physical properties of a solution are different from those of the pure solvent. ... Colligative properties are those physical properties of solutions of nonvolatile solutes that depend only on the number of particles present in a given amount of solution, not on the nature of those particles.

Which statement describes a similarity between conductors and insulators?
Ivanshal [37]

Answer:

They can both be used in an electric circuit.

Explanation:

Though conductors and insulators are very different from each other but still they have a similarity that "they can both be used in an electric circuit".

Conductors are the material that allows electricity to flow and insulators have high resistance and do not allow electricity to flow.

Both conductors and insulators are used in an electric circuit as conductor is used in wires, batteries and bulb to flow current while insulators are used in insulation of wire, switches, plugs and etc. Combination of them makes the circuit shock free.

Hence, the correct answer is "They can both be used in an electric circuit."

Give three examples of energy being changed to other forms.
dimaraw [331]
Solar: rays from the sun shine on solar pannels creating energy which is a renewable energy.
Water: water stored at a dam flows through turbines creating energy which is a renewable energy
Fossil fuels: fossil fuels are extracted from the ground the burned to create energy and this is a nonrenewable resource.
Hope this helps :)
