Question

Experimental Set Up consider the balanced equations for the following reactions of metals with HCI, each written for the production of mole of H2 (one equivalent of H2) Na + HCI --> NaCl + H2 Ź Mg + HCI --> MgCl2 + H2 Ś Al + HCI --> į AlCl3 + H2 a. What additional datum would be needed in order to find the atomic mass of your metal from the equivalent mass? IDENTIFY your unknown metal from the equivalent mass and the Periodic Table. You may encounter some difficulty, if you have an alloy. Show all setups. Be careful with significant figures.
