Problem- 1. Write and balance the equations for the reaction of the following active metals with hydrochloric acid: sodium, aluminum, zinc, calcium
2. If 0.04250 g of magnesium is reacted with an excess of hydrochloric acid, calculate the theoretical colume at STP of hydrogen gas produced.
3. If 44.00 mL of hydrogen is actually collected OVER WATER from the above reaction conducted at 22.0 C and 759.2 torr, calculate the volume of dry hydrogen produced at STP.
4. Calculate the percentage error of this experiment
5 Explain the reason for each following procedures in this experiment:
a) Cleaning the magnesium strip with sandpaper
b) Equalizing the water levels inside and outside the eudiometer
Kindly Please put your best effort to provide the solution of above problem
