Hi can someone help me with this ill give brainliest asap

Balanced equation :

C₂H₆+7O₂⇒4CO₂+6H₂O

Conservation of mass :

In a closed / isolated system, the total mass of the substance before the reaction will be equal to the total mass of the reaction product.

Conservation of mass applies to a closed system, where the masses before and after the reaction are the same

This is the basis of reference, that the total atoms in the reactants will be equal to the total atoms in the product

The elements in the reaction will also be found in the product, but in the form of other compounds

Reaction

Let's look at the number of atoms in the reactants and products

C,left=2, right=1

H,left=6, right 2

O,left=2, right 3

So the equation not balanced

To balance, we can use the formula for burning alkanes or by using mathematical equations

1. Formula(in this case the hydrocarbon is ethane,n=2)

2. Mathematical equations

give equation

C₂H₆+aO₂⇒bCO₂+cH₂O

C,left=2, right=b⇒b=2

H,left=6,right=2c⇒2c=6⇒c=3

O,left=2a,right=2b+c⇒2a=2b+c⇒2a=2.2+3⇒2a=7⇒a=7/2

C₂H₆+7/2O₂⇒2CO₂+3H₂O x 2

C₂H₆+7O₂⇒4CO₂+6H₂O

elements

explanation:

yes the other ones are right just show me a pic of ur face cuz u look hot
