In this reaction, magnesium reacts with sulphuric acid to produce magnesium sulfate and hydrogen gas. Now, we need to count the number of atoms of each element involved in the reaction and tabulate to find out whether the chemical equation is balanced or not. For the above equation, Thus, ...
If possible, make the equation more informative by indicating the physical states of the reactants and products, the heat changes that occur in the reaction, and the conditions under which the reaction occurs. This step may be skipped if you do not have enough information about the physical s...
If you were to describe a chemical reaction in a sentence, it would be quite long. To express it in a shorter form, we can write it as a word-equation. For example, the reaction between magnesium and oxygen to give magnesium oxide can be represented as follows – Magnesium + Oxygen →...
Step 5: Check the equation once more and ensure the charge and the number of elements on both sides of the equation are balanced. Example Hydrogen (H2) and oxygen (O2) combine to produce water (H2O). H2 + O2→ H2O This reaction is unbalanced. To balance it, first multiply the oxygen...

Thus, in a chemical reaction, the total mass of matter involved in the reaction should be constant. Hence, the mass of the reactants equals the mass of the products. Because of this, when a chemical equation is used to represent a reaction, the number of atoms or moles of each elem...
One example of a chemical reaction is the combination of hydrogen gas and oxygen gas to form liquid water. This is known as a synthesis reaction. What is the simple definition of a chemical reaction? A chemical reaction occurs when one or more chemical compounds undergo a process that chemica...
Give an example. Explain how a chemical equation can be used to relate the masses of different substances involved in a reaction. Why is chemical speciation important in environmental studies? Provide a concrete example. What is the use of carbon dioxide? Explain with an example. Why a...
