Which substance is the reducing agent in this reaction 2 KMnO4 plus 3Na2 SO3 plus H2 O 2MnO2 plus 3Na2 SO4 plus 2K OH?
The ion MnO4 is reduced toMnO2 and sulfur is oxidized to ion sulfate. Sulfite is the reducing agent.
Why is 2Ca plus 2HCl - 2CaCl plus H2 wrong?
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.
What is the chemical reaction for Ca plus Hci?
Ca + 2 HCl = CaCl2 + H2
Which alkali metals possesses highest reducing power?
The tendency of alkali metals to act as strong reducing agents is evident from the fact that these metals can liberate H2 from H2 O and acids. 2M+2H2O-----------------2MOH+H2 2M+2HCl------------------2MCl+H2We have already seen that Li atom loses its ns1 electron with great difficulty while Cs atom should have maximum reducing power among the alkali metals . In other words ,we can also say Li -atom ,because of its maximum ionisation energy, should have minimum reducing power and Cs atom ,because of its minimum ionisation energy ,should have maximum reducing power .The high valves of oxidation potential show that alkali metals can lose their ns1 electron quite readily and hence have a strong tendency to act as reducing agents.
What products are produced when calcium reacts with steam?
Hydrogen and lime Ca + 2 H2O --> H2 + Ca(OH)2
What is the reducing agent in CO plus H2 equals C plus H2O?
H2 - hydrogen.
What is the reducing agent in C plus 2Cl2 equals CCl4?
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.
How is hypophosphous acid?
H3PO2 a phosphorus oxoacidand a powerful reducing agent, HOP(O)H2 exists in equilibrium with the minor tautomer HP(OH)2
Which substance is the reducing agent in this reaction 2 KMnO4 plus 3Na2 SO3 plus H2 O 2MnO2 plus 3Na2 SO4 plus 2K OH?
The ion MnO4 is reduced toMnO2 and sulfur is oxidized to ion sulfate. Sulfite is the reducing agent.
Iron ore is reduced to iron by a reaction with?
A reducing agent like Hydrogen(H2), Carbon(C), Carbon monoxide(CO) or Ammonia(NH3)
Balanced Chemical reaction of HCl on Ca?
The chemical reactin is:Ca + HCl = CaCl2 + H2
Is iron an oxidizing agent or reducing agent?
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
Is HCl an oxidizing agent or reducing agent?
reducing agent because it has room to gain electrons so it will be oxidized by an oxidizing agent. It is in the reduced form and can reduce other molecules by accepting their electrons. Therefore, NADH is the reducing agent and NAD+ is the oxidizing agent
Is sulfur in this chemical reaction a oxidation agent or reduction agent in S plus H2 plus 2O2 --- H2SO4?
It is safer to claim it as neither - not least because the reaction would/does not work. Far safer to say that the sulphur is oxidised (which, you could argue, makes it a reducing agent).
What is the balanced chemical equation for Ca and H2O?
Ca + 2H2O ==> Ca(OH)2 + H2
What is the chemical equation Ca plus H2SO4?
Ca + H2SO4 = CaSO4 + H2
What is the balanced equation for Ca HCl?
2HCl + Ca -> CaCl2 + H2 (gas)
