A metal M with a mass of 0.420 g completely reacts with

Chapter 14, Problem 23CI

(choose chapter or problem)

A metal M with a mass of 0.420 g completely reacts with 34.8 mL of a 0.520 M HCl solution to form aqueous MCl3 and H2 gas. (6.1, 6.5, 6.6, 6.7, 7.8) When a metal reacts with a strong acid, hydrogen gas forms.a. Write a balanced equation for the reaction of the metal M(s) and HCl(aq).b. What volume, in milliliters, of H2 at 720. mmHg and 24 °C is produced?c. How many moles of metal M reacted?d. Use your results from part c to determine the molar mass and name of metal M.e. Write the balanced equation for the reaction.
