A student used 0.0938 g of Mg and collected 96.21 mL of H2 gas (their eudiometer tube is larger than the one we used) over water at 29.3°C on a day when the atmospheric pressure was 786.8 mmHg. The level of the solution in the tube was 12.6 mm above the level in the beaker when the reaction was complete. What was the experimental value for R in units of L mmHg mol1- K-1? How does this compare (calculate percent...

A. In the experiment, The molar volume of a gas. Mg (s) + 2HCl (aq) = MgCl2 (aq) + H2 (g), the magnesium ribbon was dissolved in hydrochloric acid, a monoprotic acid, to produce H2 gas. If phosphoric acic, a triprotic acid, were used to react with the magnesium rather than hydrochloric acid, does that affect the amount of H2 gas produced?. Write balanced equations for the reaction og Mg with 1) HCl and 2) phosphoric acid to help explain...

In an experiment, 26.0 g of metal was heated to 98.0°C and then quickly transferred to 150.0 g of water in a calorimeter. The initial temperature of the water was 20.5°C, and the final temperature after the addition of the metal was 32.5°C. Assume the calorimeter behaves ideally and does not absorb or release heat. What is the value of the specific heat capacity (in J/g•°C) of the metal?

In an experiment, 25.5 g of metal was heated to 98.0°C and then quickly transferred to 150.0 g of water in a calorimeter. The initial temperature of the water was 23.0°C, and the final temperature after the addition of the metal was 32.5°C. Assume the calorimeter behaves ideally and does not absorb or release heat. 1.) What is the value of the specific heat capacity (in J/g•°C) of the metal? _____ J/g•°C
