Question

NEED HELP ASAP! Write a statement explaining your claim about whether or not the equation is correctly balanced.

Answer 1

Answer:

I think that it it correctly balanced that is my opinion and, because  the way it is set up, that the answer will tell you weather or not it is correctly balanced or not.

Answer 2

Evaluating the number of atoms of each element on the product and reactant side, we can conclude that the student's equation isn't balanced.

Given the chemical reaction :

$Al_{4}C_{3} + 6H_{2}O ---> 3CH_{4} + 4Al(OH)_{3}$

For a balanced equation, the number of atoms of each element in the product side must be equal to that on the reactant side.

Number of hydrogen :

Reactant side = (6 × 2) = 12

Product side = (6 × 2) + (6 × 2) = 12 + 24 = 24

Product side ≠ reactant side ; Hence, the equation isn't balanced

The balanced equation for the reaction goes thus :

$Al_{4}C_{3} + 12H_{2}O ---> 3CH_{4} + 4Al(OH)_{3}$

Reactant side :

Al = 4

H = (12 × 2) = 24

O = 12

C = 3

Product side :

H = (6 × 2) + (6 × 2) = 12 + 24 = 24

Al = 4

O = 4 × 3 = 12

C = 3

Therefore, the student's equation isn't balanced, the balanced version of the equation has been given .
