<u>Answer:</u>

<em>The law of conservation of energy remains the same for any kind of chemical or physical energy. Since that happens inside laboratory or outside it anywhere in the nature.</em>

<u>Explanation:</u>

Any example that will be considered will demonstrate <em>no change in ultimate mass and any kind of energy</em> that is involved in the reaction can only change the form of its nature while the total energy remains conserved.

There can be <em>no gain or loss in mass or energy</em> in any reaction that takes place reactant and product and energy should remain same.

<em>For example rolling balls force </em>with which it is thrown the distance reached by the ball would depend on the frictional energy and air resistance acting on it and on considering these forces it shall remain equal to the original source.

Ionic crystals are excellent insulators and can hold a large amount of heat before melting or boiling.
sweet-ann [11.9K]
It is a true fact that ionic crystals are excellent insulators and can hold a large amount of heat before melting or boiling. The correct option among the two options that are given in the question is the first option. Salt is a great example of ionic crystals and we know that it takes a huge amount of time to melt or boil.

Yuki888 [10]

Answer:

8.34

Explanation:

1) how much moles of NH₃ are in the reaction;

2) how much moles of H₂ are in the reaction;

3)  the required mass of the H₂.

all the details are in the attachment; the answer is marked with red colour.

Note1: M(NH₃) - molar mass of the NH₃, constant; M(H₂) - the molar mass of the H₂, constant; ν(NH₃) - quantity of NH₃; ν(H₂) - quantity of H₂.

Note2: the suggested solution is not the shortest one.

What is the difference between a physical and chemical change? (Use words reactants, products, atoms and molecules.)
jeka94

Answer:

A physical change, such as a state change or dissolving, does not create a new substance, but a chemical change does. In a chemical reaction, the atoms and molecules that interact with each other are called reactants. In a chemical reaction, the atoms and molecules produced by the reaction are called products.
