What precipitate is formed if you add HCl to CuO and then add BaCl2?
HCl and CuO form CuCl2 and H2O, BaCl2 does not react with CuCl2 so it may react with water so the precipitate are of Ba(OH)2 Added: But this is not the case because to dissolve CuO first you'll need a bit more acid to get it completely dissolved. If the solution would become neutral then Cu(OH)2 would precipitate at concentration of [Cu2+] more than 1.6*10-5 (because Ks=1.6*10-19) rather than Ba(OH)2 (Ks=10-10)
How many moles of CuO are needed to react with 4 moles of HCL?
4 mole cuO X 2/1 = 8 mole Hcl
How many moles of hcl are needed to react with 4 moles of cuo?
4 mole cuO X 2/1 = 8 mole Hcl
Why does CuO plus 2 HCl make H2O plus CuCl2?
It's a simple acid-base reaction, your acid being your 2HCl and your base being CuO. Acid-base reactions form water, leaving behind a salt (CuCl2).
What happen when NaHCO3 plus HCl?
When NaHCO3 plus HCL reacted they forum two different substance that is H4CO3+NaCl, That is the balanced formula.
CuO plus HCL-CuCl2 plus H2O?
CuO + 2HCL - CuCl2 + H2O

How many moles of hcl are needed to react with 4 moles of cuo?
4 mole cuO X 2/1 = 8 mole Hcl

What happen when NaHCO3 plus HCl?
When NaHCO3 plus HCL reacted they forum two different substance that is H4CO3+NaCl, That is the balanced formula.
Balance hydrochloric acid plus silver nitrate?
This equation is: AgNO3 + HCl--------- AgCl + HNO3 AgCl is a white precipitate.
Why should concentrated hcl help clean out a test tube soiled with cu2o?
The HCl will react with the CuO in a double replacement reaction given by the equation: 2HCl + CuO --> CuCl2 + H2O. Copper(II) chloride is water soluble, so it will clean right out.
How do you prepare cupric chloride solution?
CuO + 2 HCl -> CuCl2 + H2O Please see the link.
What happens when casein is added to hcl?
When casein is added to HCl, it becomes a precipitate. It does this because of a process called acid coagulation.
What is the balanced equation for copper II oxide and hydrochloric acid?
This equation is 2 HCl + CuO -> CuCl2 + H2O.
How do you differentiate between nitric acid and hydrochloric acid?
Add AgNO3 solution. If a white precipitate (AgCl), it's HCl. If no precipitate, HNO3.
