For which compound is the process of dissolving in water exothermic?

Chemistry
1 answer:
Leokris [45]3 years ago
8 0

Answer: Option (2) is the correct answer.

Explanation:

A chemical reaction in which reactants absorb energy is known as an endothermic reaction. Also, in this reaction energy of reactants is less than the energy of products.

For example, when ammonium chloride is dissolved in water then the solution becomes cold as the reaction is endothermic in nature.

Whereas a chemical reaction in which energy is released is known as exothermic reaction. Also, in this type of reactions energy of reactants is more than the energy of products.

For example, when NaOH is dissolve in water then heat is released as it dissociates into sodium and hydroxide ions. Further, product formed that is, species sodium and hydroxide ions acquire low energy state. Hence, the reaction is exothermic in nature.

Thus, we can conclude that NaOH is the compound in which process of dissolving in water is exothermic.

How many grams of magnesium nitride is required to produce 25.00 g of magnesium hydroxide?
Lesechka [4]

Answer:

25 grams of Mg(OH)2 will be produced by 14.424 gram of Mg3N2

Explanation:

The balanced equation is

Mg3N2 + 6H2O -> 3Mg(OH)2 + 2NH3

Molecular weight of magnesium nitride = 100.9494 g/mol

Molecular weight of magnesium hydroxide = 58.3197 g/mol

one mole of Mg3N2 produces three moles of 3Mg(OH)2

100.9494 g/mol of  Mg3N2 produces 3* 58.3197 g/mol of Mg(OH)2

1 gram of Mg3N2 produces

\frac{3* 58.3197}{100.9494 } \\1.733grams of Mg(OH)2

Or 1.733 grams of Mg(OH)2 will be produced by 1 gram of Mg3N2

25 grams of Mg(OH)2 will be produced by 14.424 gram of Mg3N2

Is it possible to transfer heat from a cold reservoir to a hot reservoir?
tankabanditka [31]

Answer is: B.) Yes, if work is done, this transfer process can take place.

For example,  air conditioner involves a cyclic process that transfers heat from a cold reservoir to a hot reservoir, but with use of electricity.

Thermal conductuction is the transfer of heat through physical contact. Thermal conduction is the transfer of heat by microscopic collisions of particles. Heat spontaneously flows from a hotter to a colder body.

The process of heat conduction depends on four basic factors: the temperature gradient, the cross section of the materials involved, their path length and the properties of those materials.
