Assignment:
Q1. 0.655g of antacid is weighed and mixed with 50.0 mL of excess 0.100 M HCl. The excess acid required 3.90 mL of 0.100 M NaOH for back titration. Calculate the neutralizing power of the antacid in terms of mmol H+ per gram of antacid.
Q2. The amount of ozone in the atmosphere is influenced by concentrations of gases that contain only nitrogen and oxygen, among others. The table gives the masses of nitrogen that combine with 1.00g of oxygen to form three of these compounds.
Compound A: Mass of Nitrogen= 0.875
Compound B: Mass of Nitrogen= 0.438
Compound C: Mass of Nitrogen= 0.350
Determine the ratios of the masses of nitrogen that combine with 1.00 of oxygen in these compounds. Are these data consistent with the law of multiple proportions?
Provide complete and step by step solution for the question and show calculations and use formulas.
