Question

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

Explanation:

Step1: Balance the chemical equation

For a hydrocarbon reacting with oxygen (\(O_2\)) in a combustion reaction, the general form is \(C_xH_y + zO_2
ightarrow aCO_2 + bH_2O\).
For \(C_{10}H_8+12O_2\), balance the carbon atoms: There are 10 carbon atoms in \(C_{10}H_8\), so \(a = 10\) (since each \(CO_2\) has 1 carbon atom).
Balance the hydrogen atoms: There are 8 hydrogen atoms in \(C_{10}H_8\), and each \(H_2O\) has 2 hydrogen atoms. So \(b=\frac{8}{2}=4\).
Now check the oxygen atoms: On the left - hand side, there are \(12\times2 = 24\) oxygen atoms from \(O_2\). On the right - hand side, from \(CO_2\) we have \(10\times2=20\) oxygen atoms and from \(H_2O\) we have \(4\times1 = 4\) oxygen atoms. \(20 + 4=24\) oxygen atoms.

Answer:

A. \(10CO_2+4H_2O\)
