Answer:

D

Explanation:

The specific heat capacity is the heat required to raise the temperature of 1kg of a substance by 1oC. Molar heat capacity of a substance is the heat requiredto raise the temperature of 1mole of a substance by 1oC. Molar heat capacity and specific heat capacity both decreases with increase in atomic weight. Increase in atomic weight also means increase in density of the substance.

What ratio of nitrogen and hydrogen molecules would result in no left-over reactants? Explain your answer.
madam [21]

A ration, Nitrogen to Hydrogen, of 1 : 3 would result in no left-over reactants

Explanation:

This is because Nitrogen and Hydrogen would react to form ammonia as shown in the following reaction below;

N₂ (g) + 3H₂ (g) → 2NH₃ (g)

For every mole of Nitrogen gas, you would require 3 moles of Hydrogen gas. This way they would react to form Ammonia with no leftover reactants.

Answer:

Nuclear fusion is a reaction in which two or more atomic nuclei are combined to form one or more different atomic nuclei and subatomic particles. The difference in mass between the reactants and products is manifested as either the release or the absorption of energy. 

Explanation: Read this and you might be able to figure it out for yourself ☺️☺️☺️

Conversion of minus 1 coulomb meter in debye
Viktor [21]

Answer:

-1 Coulomb meter = -2.997 × 10²⁹ Debye

Explanation:

Given:

Coulomb meter = -1 CM

Find:

In debye

Computation:

We know that,

1 Coulomb meter = 299,792,458,178,090,000,000,000,000,000 Debye

So,

-1 Coulomb meter = -299,792,458,178,090,000,000,000,000,000 Debye

-1 Coulomb meter = -2.997 × 10²⁹ Debye
