Answer: Option (c) is the correct answer.

When an atom donates or shares its valence electrons with other atoms then it results in the formation of a new atom. This means a chemical has occurred as the chemical composition of products will be different from the reactants.

Whereas a substance is a matter which contains specific composition with some specific properties.

When two or more substance are mixed together then it is known as a mixture. It is not necessary that substances added will combine with each other.

When atoms of similar element chemically combine together then they result in the formation of a molecule.

For example, Cl + Cl \rightarrow Cl_{2}

Therefore, we can conclude that when components do not combine chemically, it is a mixture.

How many total electrons does the P^3- ion have? O a. 3 O b. 31 O c.1 O d. 15 O e. 18
STALIN [3.7K]

Answer:

e. 18

Explanation:

A neutral P atom has an atomic number of 15, which means there are 15 protons in the atom. In order to be neutral, the P atom must also have 15 electrons.

The P³⁻ anion has 3 electrons more than the neutral P atom since it has a charge of -3.

Thus, the total number of electrons are 15 + 3 = 18 electrons.

put 8 in front of the oxygen in the reactants side to make it 16 molecules then put a 5 in front of the co2 in the product side to balance the carbon atoms then put a 6 in front of the H20 on the product side this balances both the hydrogen and oxygen atoms here is a representation

C5H12(g)+8O2(g)=5CO2(g)+6H20

A major disadvantage of a corporation is the
Nikitich [7]
A major disadvantage of a corporation is the double taxation of the corporation's income and of dividends paid to shareholders.
<span>Corporations end up paying taxes twice. The corporation pays tax when it shows a profit. Secondly the corporation pays tax when it pays out dividends to its shareholders.  Sole proprietorships and partnerships are taxed as owners of the business. The owners of a corporation are taxed individually from the corporation. The advantage of this is that the owners of a corporation are not taxed on the corporation's profit. </span>

kkurt [141]

Answer : Amoxicillin Suspension 125 mg/ 5 ml is 125 mg of Amoxicillin per 5 ml of suspension is an example of weight to volume.

Explanation :

Weight by volume (w/v) means that the mass of solute present in 100 mL volume of solution.

Weight by weight (w/w) means that the mass of solute present in 100 gram of solution.

Volume by volume (v/v) means that the volume of solute present in 100 mL volume of solution.

As per question, amoxicillin suspension is, 125 mg/ 5 ml that means 125 mg of Amoxicillin present in 5 mL of suspension. So, it is an example of weight to volume.

Hence, it is an example of weight to volume.
