Balance the following equations: b. C5H10O2(𝑙)+O2(𝑔)⟶CO2(𝑔)+H2O(𝑔)

Guida verificata passo dopo passo

Identify the type of chemical reaction. This is a combustion reaction where an organic compound reacts with oxygen to produce carbon dioxide and water.

Write down the unbalanced equation: \( \text{C}_5\text{H}_{10}\text{O}_2(\ell) + \text{O}_2(g) \rightarrow \text{CO}_2(g) + \text{H}_2\text{O}(g) \).

Balance the carbon atoms first. There are 5 carbon atoms in \( \text{C}_5\text{H}_{10}\text{O}_2 \), so place a coefficient of 5 in front of \( \text{CO}_2 \).

Next, balance the hydrogen atoms. There are 10 hydrogen atoms in \( \text{C}_5\text{H}_{10}\text{O}_2 \), so place a coefficient of 5 in front of \( \text{H}_2\text{O} \).

Finally, balance the oxygen atoms. Count the total oxygen atoms on the right side and adjust the coefficient of \( \text{O}_2 \) on the left side to balance the equation.

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Stoichiometry

Stoichiometry is the branch of chemistry that deals with the quantitative relationships between the reactants and products in a chemical reaction. It involves using balanced chemical equations to determine the amounts of substances consumed and produced. Understanding stoichiometry is essential for balancing equations, as it ensures that the law of conservation of mass is upheld.

Balancing Chemical Equations

Balancing chemical equations involves adjusting the coefficients of reactants and products to ensure that the number of atoms for each element is the same on both sides of the equation. This process reflects the conservation of mass, where matter is neither created nor destroyed. It is crucial for accurately representing the reaction and predicting the amounts of products formed.
