Question

use the reaction to answer the question.
c₁₀h₈ + 12o₂ →?
which products are expected from the reaction?
(1 point)
10co2 + 8h2o
10co2 + 4h2o
10c + 4h2o + 10o2
10co2 + 8h + 2o2

Explanation:

Step1: Balance carbon atoms

In \(C_{10}H_8\), there are 10 carbon atoms. In a complete combustion reaction of a hydrocarbon (\(C_xH_y\)) with \(O_2\), carbon forms \(CO_2\). So, from 10 carbon atoms, we get \(10CO_2\).

Step2: Balance hydrogen atoms

In \(C_{10}H_8\), there are 8 hydrogen atoms. Hydrogen forms \(H_2O\). Since each \(H_2O\) has 2 hydrogen atoms, the number of \(H_2O\) molecules is \(\frac{8}{2}=4\).

Step3: Check oxygen atoms

For \(10CO_2\), there are \(10\times2 = 20\) oxygen atoms from \(CO_2\). For \(4H_2O\), there are \(4\times1=4\) oxygen atoms from \(H_2O\). Total oxygen atoms in products: \(20 + 4=24\). In reactants, \(12O_2\) has \(12\times2 = 24\) oxygen atoms.

Answer:

10CO2 + 4H2O
