Is Cu oxidized or reduced in CuO plus H2 yields Cu plus H2O?
Cu is oxidized. The oxidation number goes from 0 in Cu to +2 in CuSO4. S is reduced. The oxidation number goes from +6 in H2SO4 to +4 in SO2. The oxidizing agent is H2SO4 since it causes Cu to be oxidized. The reducing agent is Cu since it causes S in H2SO4 to be reduced.
What happens when calcium is mixed with water?
The reaction is:Ca + H2O = Ca(OH)2 + H2
What is the strongest acid H2O or h2?
H2o
What does Na plus H2O plus H2 equal?
Na+H2o+H2=2 Nhoh
What is the word equation for the reaction between copper oxide and sulfric acid?
CuO + H2SO4 ----> CuSO4 + H2O The products are Copper(II) sulphate and water
What is the limiting reactant when 41.4 grams of cuo are exposed to 2.56 grams of h2 according to the equation cuo h2 yields cu h2o?
cuo
How would you get copper from copper oxide?
you obtain Cu from CuO only by reducing with hydrogen or carbon monooxide: CuO + H2 → Cu + H2O
What is the symbol equation for Copper oxide Hydrogen --------- Copper Water?
CuO + H2 ----> Cu + H2O
What happens when hydrogen reacts with copper oxide?
When Hydrogen Is Passed Over Hot Tubgsten Oxide (WO3) WO3 + 3H2 ----------------> 3H2O + W
What is the equation for the reaction copper II oxide reacts with hydrochloric acid?
CuO + H2 ------> Cu + H2O. You shouldn't say "plus" for the reactions, it has to be the arrow as the arrow symbolises lots of complicated reactions, making it different to adding them together.
Is Cu oxidized or reduced in CuO plus H2 yields Cu plus H2O?
Cu is oxidized. The oxidation number goes from 0 in Cu to +2 in CuSO4. S is reduced. The oxidation number goes from +6 in H2SO4 to +4 in SO2. The oxidizing agent is H2SO4 since it causes Cu to be oxidized. The reducing agent is Cu since it causes S in H2SO4 to be reduced.
what happens CO is dissolved in water?
Co + h2o = co + h2
What is the chemical reaction of Cu plus AlCl3?
Cu + HNO3 = CuNO3 + H2 or copper nitrate and hydrogen gasCu + 4 HNO3 --> Cu(NO3)2 + 2NO2 + 2H2OThe brown colored gas that comes of the reaction is NO2.
What is the balanced equation of copper hydroxide hydrochloric acid?
copper+hydrocloric acid=Copper chloride+hydrogen Cu+2HCl=CuCl2+H2 The first part of the salt is from the acid The second part is from the alkali, metal, or metal carbonate hydrochloric acid gives chloride sulfuric acid give sulfate nitric acid gives nitrate
How do you distinguish between the gases H2 and No2?
okay, we can see in the other way, if you have enough chemicals to use for those (H2 and H2S) --method 1: you can use your nose to smell it, the H2S has the smell, like ... rotten eggs, smell it and you will see, lol, but especially that is really harmful, the other one is H2 --method 2: you can use CuO (black) include heat, so with heat, the H2 makes the CuO turn red, because H2+CuO --> Cu+ H2O, because the red color is the color of Cu, the other one is H2S --method 3: we use the H2S , we put the AgNO3 (aq) we can see the H2S reacts with the AgNO3 and we see the black color, because AgNO3 + H2S --> Ag2S + 2HNO3, the black color is the color of Ag2S after reaction, with H2, it can not react with AgNO3, I'm not sure about this one because, if H2 reacts with AgNO3 , the products are HNO3 and Ag, but HNO3 is the strong acid, so the products will become the reactants, so jsut look the black color in the test tube which belong to the Ag2S we have many other ways to distinguish these one, but with me these methods is enough for you to be easy to distinguish H2 and H2S
What happens when dilute hydrochloric acid is poured on a copper plate?
dil. hcl + cu = cucl2 +h2
