Question

In a combination reaction, the number of products are ________

Answer 1

As we know that in chemistry, equations play a major role. In the reaction three things are main. There are reactants, products and reaction conditions. The reactants are always on the left side of the equation. If more than one reactant in the equation means by using plus sign. The products are always on the right side of the reaction. Something here also follows. More than one product by using plus sign. In between reactant products are used arrows to find the reaction direction in the equation.

Complete answer:
We need to know that the combination reaction is one type of the chemical reaction. In these combinations, two or more reactants give a single product.
The general representation of combination reaction is given below,
$A + B \to P$
A and B are the reactants of the combination reaction and P is the product of this reaction.
Example of combination reaction,
$2Na + C{l_2} \to 2NaCl$
Formation of sodium chloride is an example of combination reaction in the chemical reaction.
According to the above discussion, we conclude in a combination reaction, the number of products are only one.

Note:
We have to know that reactions in chemistry are classified as two types. This classification is based on the reaction steps. There are simple reactions and complex reactions. The simple reaction is reactant to the product in the single step. The complex reaction is reactant to the product in the multiple steps. These multiple steps are called elementary steps. These elementary steps need mechanisms that are used for understanding the reaction proceeding. The mechanism is used to understand reactants to intermediate and intermediate to product in the chemical reaction. In balanced chemical reaction wise, we predict the side product of the reaction. In some cases we are not able to attain the balance by changing the mole. In that case we use the number of countable ions in the product and reactant side of the chemical reaction. In chemistry, redox reaction is one of the types of major reactions. In this redox reaction two methods are used to attain the balanced chemical reaction. There are ion-electron methods and the oxidation number method.
