Question

chemical equation with chemical formula. ​

Answer 1

Answer and Explanation:

Chemical reactions are processes in which the chemical composition of one or more substances (elements or compounds) change

Chemical reactions are of different types depending upon various criteria

The different criteria can be :

1. Number of reactants are products
2. Speed or rate of reaction
3. Oxidation number etc

The different reactions can be :

1. Decomposition reaction
2. Combination reaction
3. Slow reaction
4. Fast reaction
5. Reduction reaction
6. Oxidation reaction etc

The balanced chemical equation is given by :

$\huge \text{\boxed{2{Na + 2H_2O \rightarrow 2NaOH+H_2}}}$

Answer 2

$\mathtt{\huge{\underline{\red{Question\:?}}}}$

✴ Chemical equation with chemical formula :-

Na + 2H2O ------->

$\mathtt{\huge{\underline{\green{Answer:-}}}}$

✏ Na(s) + 2H2O(l) ---> 2NaOH(s) + H2(g)

$\mathtt{\large{\underline{\pink{Balancing\:of\:Reaction:-}}}}$

• First we have to identify the element of the equation.

• The number of atoms of each type of atom must be the same on each side of the equation once it has been balanced.

• The total charge must be the balanced on both sides .

• We have to start with an element of reaction .

• The number of atoms of the element is the same on each side of the equation.

• Balance the equation, in the formulas. Repeat with the same thing with another element.

• Similarly balance all the elements.
