<h2>GREETINGS!</h2><h2>_____________________________________</h2><h3>Answer:</h3>

ITS C_{4}H_{10} AND C_{5}H_{12}

<h2>_____________________________________</h2><h3><u>GENERAL FORMULA OF ALKANE</u></h3><h3>                    C_{n}H_{2n+2}</h3>

Where n is the number of CARBONS

<h2>_____________________________________</h2>

A)

By using the General Formula of Alkanes having 4 carbon atoms is

                        C_{4}H_{2x4+2}

                        C_{4}H_{10}

C)

By using the General Formula of Alkanes having 5 carbon atoms is

                         C_{5}H_{2x5+2}

                         C_{5}H_{12}

<h2>_____________________________________</h2>

IF YOU USE THE SAME FORMULA FOR THE OTHER TWO OPTIONS THE OUTCOME WILL NOT BE AS SAME AS GIVEN IN THE QUESTION SO THOSE TWO ARE CAN NOT BE OUR ANSWER

<h2>_____________________________________</h2><h2>HOPE THIS HELPS!</h2>

two substances react and the mass is recorded.The mass of the products does not equal the mass of the reactants .Which is the be
Dovator [93]
Mass can’t be destroyed. So since not all the mass was found in the products, that simply means that it was lost to the environment. For example, let’s say hydrogen and oxygen are the reactants and we get water in the product. Now that oxygen could have reacted with something else that we didn’t take into account when measuring the mass of the H2O released.

Tldr, some of the reactants were lost to the surroundings
