The chemical reaction of calcium (Ca) with hydrochloric acid (HCl) is: Ca + 2HCl -> CaCl2 + H2. This reaction results in the formation of calcium chloride (CaCl2) and hydrogen gas (H2).
The ion MnO4 is reduced toMnO2 and sulfur is oxidized to ion sulfate. Sulfite is the reducing agent.
Hydrogen and lime Ca + 2 H2O --> H2 + Ca(OH)2
The equation is not balanced. If we combine hydrochloric acid (HCl) and calcium (Ca), it will look like this:2HCl + Ca → CaCl2 + H2↑The H2 here is hydrogen gas.
In the reaction involving copper(II) oxide (CuO) and hydrogen gas (H2), hydrogen acts as a reducing agent. The hydrogen reduces CuO to metallic copper (Cu), while itself being oxidized to form water (H2O). This process involves the transfer of electrons, where CuO gains electrons to form Cu, and H2 loses electrons to form H2O. Overall, the chemical reaction can be summarized as: CuO + H2 → Cu + H2O.
H2 - hydrogen.
H2 + Cl2 --> 2HCl Think of it like this. H2 begins with two electrons, Cl2 begins with 14 (it is diatomic and originally has 7 electrons, so 7 + 7 = 14). The reducing agent is the one being oxidized (you need to remember that!) and if something is being oxidized, it is going from having more electrons to less electrons. 2HCl has 16 electrons (where H has two and Cl has fourteen), so, unless there is a charge on any of these compounds that you did not include in your question, no, Cl is not the reducing agent.
The chemical reactin is:Ca + HCl = CaCl2 + H2
The balanced chemical equation for the reaction between calcium (Ca) and water (H2O) is: Ca + 2H2O -> Ca(OH)2 + H2. This reaction produces calcium hydroxide (Ca(OH)2) and hydrogen gas (H2).
H3PO2 a phosphorus oxoacidand a powerful reducing agent, HOP(O)H2 exists in equilibrium with the minor tautomer HP(OH)2
The ion MnO4 is reduced toMnO2 and sulfur is oxidized to ion sulfate. Sulfite is the reducing agent.
The chemical equation for the reaction between calcium (Ca) and sulfuric acid (H2SO4) is: Ca + H2SO4 -> CaSO4 + H2. This reaction produces calcium sulfate (CaSO4) and hydrogen gas (H2).
The chemical reaction of calcium (Ca) with hydrochloric acid (HCl) is: Ca + 2HCl -> CaCl2 + H2. This reaction results in the formation of calcium chloride (CaCl2) and hydrogen gas (H2).
The balanced equation for the reaction between calcium (Ca) and hydrochloric acid (HCl) is: Ca + 2HCl -> CaCl2 + H2
Hydrogen and lime Ca + 2 H2O --> H2 + Ca(OH)2
The molecular equation for the reaction between calcium and water is: Ca(s) + 2H2O(l) -> Ca(OH)2(aq) + H2(g). The net ionic equation for the reaction is: Ca(s) + 2H2O(l) -> Ca^2+(aq) + 2OH^-(aq) + H2(g).
Zinc is a transition element with general oxidation state as +2. It gets easily oxidised to its oxidation state of +2 by elements which are less reactive than zinc . For example: 2Zn + H2O --> Zn2O + H2
