Option (C) is the correct answer.
In the chemical reaction, reactants are the starting elements or compounds which will chemically react and will form the products. Reactants are only present on the left hand side of the reaction and products are present on the right hand side of the reaction.
Reactants present in the reaction is completely used up in the reaction to form products implies no traces of reactants will be present in the product side.
For example:
Here, hydrogen and oxygen are the reactants whereas water is the product (new substance). Hydrogen reacts with oxygen and form water i.e. hydrogen and oxygen is completely used up in the reaction to form new substance i.e. water.
Hence, substances that are used up in a reaction is known as reactants of the reaction.

Hello there!
First, we need to know what compounds are. Compounds "are pure substances that are made up of two or more elements that are chemically combined in fixed mass ratios."
Now we need to understand what chemical formulas are.
The compounds have a chemical formula which tell us that
a) the elements that are present in the compound
b) the ratio of these elements in the compound
What are some chemical formulas for compounds?
Well, we start with water. The chemical formula for water is H2O
When we go back to the definition of compounds, it says it is when
a pure substance that are made up two or more elements. So, whatever is a pure substance and it's made up of two elements. These elements are Hydrogen and Oxygen. And keep an mind that water is made up with metal plus non-metal.

Here are one more chemical formulas for compounds
Sodium Chloride = NaCI

Answer:
Explanation:
Acid + Base => Salt + Weak Electrolyte ... Salts are less toxic or corrosive than strong acids or bases. Also should follow with copious amounts of water to dilute the spill also.
