I have the correct answers but I need to know how to solved these problems.
Zinc reacts with acid to release hydrogen gas. Zn() + 2 HCl(aq) â ZnCl2 (aq) + H2 Ï Given the reaction above is conducted with excess hydrochloric acid and the hydrogen was collected over water. Complete the unshaded boxes in the table. 25.0°C 788.4 mmHg 23.76 mmHg Pizo (25°C) Work: PHz mmHg 32.8 ml nH2 mol Initial mass of Zn What is the molar mass of a gas with a root-mean-square speed of 442.3 m-s-1 at 25°c?
