Question

please answer the questions based on the reaction and the result provided for the experiment.

reaction is:

Mg (s) + 2HCl (aq) —-> MgCl2 (aq) +H2 (g)

the first picture is the data collected for the experiment.

If there is unreacted metal remaining at the end of the experiment, what would that do to your calculated molar volume? Be specific. Do not merely say that "it would be incorrect." Would the calculated molar volume be too small or too large? Explain your answer. Experiment 10: MOLAR VOLUME OF A GAS 4. If you had used 0.030 g of magnesium in the first trial and 0.040 g in the second, would you expect the molar volume at STP to be larger or smaller in the second trial? Explain your answer. Do not merely explain by saying molar volume is an intensive property Explain WHY its molar volume is not dependent on the sample size. 5. Hydrogen is a real gas. a) Under what conditions do you expect it to deviate from ideal gas behavior? Explain. b) Is it reasonable to consider hydrogen as an ideal gas under the conditions of this experiment? Explain.
