Question

what is the missing coefficient to make a balanced equation? 4al + ?c → al4c3 7 1 3 4

Explanation:

Step1: Analyze carbon atoms

On the right - hand side, there are 3 carbon atoms in $Al_4C_3$. On the left - hand side, carbon is present as $C$.

Step2: Determine coefficient

To balance the number of carbon atoms, if we have $x$ moles of $C$ on the left - hand side and 3 carbon atoms in the product $Al_4C_3$, then $x = 3$.

Answer:

3
