Question

data analysis

1. determine the whole number mole ratio of the two reactants.

1 hcl + 1 naoh → 1 nacl + 1 h₂o

1. find the actual balanced chemical equation for the reaction between hcl and naoh. does the mole ratio that you determined in your experiment match the actual reaction equation’s coefficients for the two reactants? explain, especially if your mole ratios do not match the coefficients.

Explanation:

Step1: Identify reactants in equation

The reactants in the equation $HCl + NaOH
ightarrow NaCl + H_2O$ are $HCl$ and $NaOH$. The coefficients in the balanced equation are both 1, so the mole - ratio of $HCl$ to $NaOH$ is 1:1.

Step2: Write balanced chemical equation

The balanced chemical equation for the reaction between $HCl$ and $NaOH$ is $HCl(aq)+NaOH(aq)
ightarrow NaCl(aq) + H_2O(l)$. If the mole - ratio determined in an experiment is 1:1, it matches the coefficients in the actual reaction equation. If it doesn't match, possible reasons could be experimental errors such as inaccurate measurements of reactant amounts, impure reactants, or errors in the titration process (if it was a titration experiment).

Answer:

1. The whole - number mole ratio of $HCl$ to $NaOH$ is 1:1.
2. The balanced chemical equation is $HCl(aq)+NaOH(aq)

ightarrow NaCl(aq)+H_2O(l)$. If the experimental mole - ratio is 1:1, it matches. If not, possible sources of error include inaccurate measurements, impure reactants, or titration errors.
