balance the chemical equation using the smallest possible whole - number coefficients. if the coefficient is 1, you may leave it blank. \n square c_{2}h_{2}(g)\rightarrowsquare c_{6}h_{6}(l)
Answer
Explanation:
Step1: Analyze carbon atoms
On the left - hand side, in $C_2H_2$, there are 2 carbon atoms, and on the right - hand side, in $C_6H_6$, there are 6 carbon atoms. To balance the carbon atoms, we need 3 moles of $C_2H_2$ for every 1 mole of $C_6H_6$ since $2\times3 = 6$. $3C_2H_2(g)\to C_6H_6(l)$
Step2: Analyze hydrogen atoms
In 3 moles of $C_2H_2$, there are $3\times2 = 6$ hydrogen atoms. In 1 mole of $C_6H_6$, there are also 6 hydrogen atoms. So the hydrogen atoms are balanced.
