An equation is a statement that two expressions have the same value, and the equal sign is a necessity. What is properties of equality? Two equations that have the same solution are called equivalent equations e.g. 5 +3 = 2 + 6.. Those reactions that go to completion and do not go in the reverse direction are usually written with an arrow pointing to the right, e.g. C + O2 -> CO2. If an equilibrium is involved and you end up with a mixture of starting materials and final product, that can be designated by an equal sign, e.g. H2 + I2 = 2HI. 5 Similar questions.

Equal Sign The equal sign or equal sign, formerly known as the equality sign, is the mathematical symbol =, indicating equality in some well-defined function. For example, in an equation, it is located between two expressions with the same value, or for which one analyses the conditions under which they have the same value. Equal to Sign.
