What Is a Metal Hydride? - ThoughtCo

29/7/2019· Metal hydrides are often used in fuel cell appliions that use hydrogen as a fuel. Nickel hydrides are often found in various types of batteries, particularly NiMH batteries. Nickel metal hydride batteries rely on hydrides of rare-earth intermetallic compounds, such as lanthanum or neodymium bonded with cobalt or manganese.

7.7: Acid–Base and Gas Evolution Reactions - Chemistry …

Here, hydrochloric acid oxidizes zinc to produce an aqueous metal salt and hydrogen gas bubbles. Recall that oxidation refers to a loss of electrons, and reduction refers to the gain of electrons. In the above redox reaction, neutral zinc is oxidized to \(Zn^{2+}\), and the acid, \(H^+\), is reduced to \(H_2(g)\).
