Ca + 2 HCl = CaCl2 + H2
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
Lithium does react with HCl (with a lowercase L) to produce lithium chloride (LiCl) and hydrogen gas (H2)
It is impossible to balance AL CI H2 because it is an incomplete equation. There are products missing from this chemical equation. If your query was how do you balance 2 HCI + 2AL then the answer would be 2 HC1 + 2 AL = 2 ALCI + H2.
When Hydrochloric Acid is added to Zinc, a product called zinc chloride is formed. Additionally, hydrogen gas (H2) is formed, by an immediate reaction.
The balanced equation is H2+ Cl2 --> 2HCl That is with a lowercase L, not an i.
ZnCl2 + H2 formed
Ca + 2 HCl = CaCl2 + H2
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
H2
Fe(s) + 2CH3COOH(aq) = Fe(CH3COO)2(aq) + H2(g)
Correctly represented, it's Mg + 2HCl --> MgCl2 + H2, and it's a single replacement reaction.
-ag=h2(g)-=fe
Fe is elemental iron and H2SO4 sulfuric acid. They'd react like: Fe(s) + H2SO4(aq) --> FeSO4(aq) + H2(g) FeSO4, iron(II)sulfate or ferrous sulfate H2, Hydrogen gas
Oxidant half reaction: 2H+ + 2e- --> H2 Reductant half reaction: Fe --> Fe2+ + 2e- Tribune ions: 2Cl- --> 2Cl-
FeCl3 + KOH ------------> Fe(OH)3 + KCl
Lithium does react with HCl (with a lowercase L) to produce lithium chloride (LiCl) and hydrogen gas (H2)
