Answer : The Product are the new substances that are created following a chemical reactions.

Explanation :

Chemical reaction : A chemical reaction occur when two or more reactants react to form a new substance.

Reactant : A substance that is involved in a chemical reaction.

Product : A new substance that is formed in a chemical reaction.

For example : $A+B\rightarrow AB$

In this, A and B are the reactants and AB is the product.

Therefore, the answer is Product.

At equilibrium, the concentrations in this system were found to be [N2]=[O2]=0.200 M and [NO]=0.400 M.

Kipish [7]

Answer:

The concentration in equilibrium of NO is 0,550M.

Explanation:

For the reaction:

N₂(g) + O₂(g) ⇄ 2NO

The equilibrium constant is defined as:

k = [NO]² / [N₂][O₂] (1)

Replacing for the concentrations in equilibrium:

k = (0,400M)² / (0,200M)(0,200M)

k = 4,000

If you add more NO until 0,700M, the equilibrium concentrations will be:

[NO] = 0,700M-2x

[N₂] = 0,200M+x

[O₂] = 0,200M+x

Replacing in (1)

4,000 = (0,700M-2x)² / (0,200M+x)²

4,000 = 4x²- 2,8x + 0,49 / x² + 0,4x + 0,04

4x² + 1,6x + 0,16 = 4x²- 2,8x + 0,49

4,4x = 0,33

x = 0,075M

That means that concentration in equilibrium of NO is:

[NO] = 0,700M - 2×0,075M = 0,550M

I hope it helps!

What is generally true about the compressibility of solids?

Ipatiy [6.2K]

Answer: Option (b) is the correct answer.

Explanation:

Compressibility means the ability to reduce or compress in size.

In solids, molecules are held together by strong force of attraction. Therefore, it requires very high force or energy to break the bond between the molecules of a solid.

As a result, compressibility of solids is low.

Whereas a hot ionized gas which contains same number of both positive or negatively charged electrons is known as plasma. Being a gas, molecules of plasma are not held by strong force of attractions.

Hence, plasma is compressible as compared to solids.

Thus, we can conclude that out of the given options, the statement compressibility of solids is lower than the compressibility of plasmas and gases is true.

A state of matter in which the electrons temporarily separate from the protons. Group of answer choices gas plasma liquid Bose-E

8090 [49]

Answer:

Plasma.

Explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states. The three (3) classical states of matter are;

I. Solid.

II. Liquid.

III. Gas

Plasma can be defined as a state of matter in which the electrons temporarily separate from the protons and as a result, it is generally referred to as the fourth (4th) state of matter due to its superheated nature.
