Which of the following will react with zinc to produce hydrogen?
What is zinc hydrogen?
Zinc hydride is an inorganic compound with the chemical formula ZnH2. ... A variety of coordination compounds containing Zn-H bonds are used as reducing agents, however ZnH2 itself has no common applications.
Does Zn react with hydrogen?
Hydrogen Replacement
Zinc reacts with hydrochloric acid to produce aqueous zinc chloride and hydrogen (figure below). In a hydrogen replacement reaction, the hydrogen in the acid is replaced by an active metal. Some metals are so reactive that they are capable of replacing the hydrogen in water.Jun 30, 2021
Does zinc make hydrogen gas?
Metals with dilute acid
When zinc reacts with hydrochloric acid it produces zinc chloride and hydrogen gas.
What charge does zinc have?
Many of the transition metals (orange) can have more than one charge. The notable exceptions are zinc (always +2), silver (always +1) and cadmium (always +2).
What is zinc Sulfate made of?
Zinc sulfate is produced by treating virtually any zinc-containing material (metal, minerals, oxides) with sulfuric acid. Specific reactions include the reaction of the metal with aqueous sulfuric acid: Zn + H2SO4 + 7 H2O → ZnSO4•7H2O + H.
What is zinc sulfuric acid?
Zinc reacts with dilute sulphuric acid to form zinc sulphate and hydrogen gas is evolved. Since the products zinc sulphate and hydrogen gas are entirely different in chemical composition and chemical properties from the reactants, the reaction is a chemical change.
Is hydrogen sulfate the same as sulfuric acid?
The HSO4- ion is commonly referred to as hydrogen sulfate (which is also called the bisulfate ion). H2SO4 can be called dihydrogen sulfate (but it is popularly known as sulfuric acid).
Is hydrogen a phosphite?
Hydrogenphosphite is a divalent inorganic anion resulting from the removal of a proton from two of the hydroxy groups of phosphorous acid. It is a phosphite ion and a divalent inorganic anion. It is a conjugate base of a dihydrogenphosphite.

What is zinc(II) hydride?What is zinc(II) hydride?
Molecular zinc (II) hydride, ZnH 2, was recently identified as a volatile product of the acidified reduction of zinc ions with sodium borohydride. This reaction is similar to the acidified reduction with lithium aluminium hydride, however a greater fraction of the generated zinc (II) hydride is in the molecular form.

How does Zn react with other metals?How does Zn react with other metals?
Zinc reacts readily with acids, alkalis and other non-metals. Extremely pure zinc reacts only slowly at room temperature with acids. Strong acids, such as hydrochloric or sulfuric acid, can remove the passivating layer and subsequent reaction with water releases hydrogen gas. The chemistry of zinc is dominated by the +2 oxidation state.
