QuestionGraphing Practice A Name Sophie
Geoff learned that hydrogen gas can how much hydrogen gas he could mat hydrochloric acid. The data he collec one minute of reaction between iron nails and varying concentrations of hydrochloric acid \begin{tabular}{|c|c|} \hline \begin{tabular}{c} Concentration of \\ hydrochloric \\ acid (mol/L) \end{tabular} & \begin{tabular}{c} Volume of \\ hydrogen gas \\ formed (mL) \end{tabular} \\ \hline 0.2 & 23 \\ \hline 0.4 & 42 \\ \hline 0.5 & 65 \\ \hline 1.0 & 120 \\ \hline 1.4 & 155 \\ \hline \end{tabular}
1. Graph the data.
2. What is the independent variable?
3. What is the dependent variable?
4. List 2 controlled variables.
5. What concentration of hydrochloric acid would be required to make 90 mL of hydrogen gas after one minute of reaction time?

Studdy Solution
Add the values:
x0.727x \approx 0.727
The concentration of hydrochloric acid required to make 90 mL of hydrogen gas after one minute of reaction time is approximately 0.727 mol/L.
