Question

state whether the following statement is true or falsechemical equation can be balanced easily by altering the formula of a reactant and product

Answer 1

Answer : FALSE

We can never change the formula of any reactant or product :( as then the reaction will only change .

A chemical reaction has reactants - the chemical substances that react together and the products are the new chemical substance .

We have to balance the equation obeying with the Law of Conservation of mass and energy .

We multiply the number of each reactant or product so that the equation is balanced .

Example coming your way :

$H_2+Cl_2\rightarrow HCl$

The reaction is balanced by multiplying HCl with 2 .

$H_2+Cl_2\rightarrow 2HCl$

Another example :

$Mg_2+O_2\rightarrow MgO$

The reaction is balanced by multiplying MgO with 2 .

$Mg_2+O_2\rightarrow 2 MgO$

Answer 2

no it is false it is balanced by equating the coefficient of product and reactant
