Answer: The only oxidation- reduction reaction is Cu (s) + 2AgNO3 (aq) → 2Ag (s) + Cu(NO3)2. Explanation: An oxidation-reduction reaction is a chemical reaction that involves an electron transfer between two species.

Try 2 HNO3, which gives 6 O atoms, and I had 2 from the Ca(OH)2 already, so I have a total of 8 O atoms now. Right side, you need 8 total, but only have 7. Since H20 has only one O atom, if you place a 2 in front of the H20, you have 2 O atoms now.

Balance the reaction of HNO3 + CaCO3 = Ca(NO3)2 + H2O + CO2 using this chemical equation balancer!

B) 2HClO4(aq) + Ca(OH)2(aq) → 2 H2O(l) + Ca(ClO4)2(aq) C) Fe(s) + 2AgNO3(aq) → 2Ag(s) + Fe(NO3)2(aq) D) MgSO4(aq) + Ba(NO3)2(aq) → Mg(NO3)2(aq) + BaSO4(s) E) None of the above is an acid-base reaction. Answer: B. Diff: 1 Type: MC Var: 1 Page Ref: 4.5 40) An acid solution is 0.100 mol L-1 in HCl and 0.200 mol L-1 H2SO4. Sep 01, 2009 · HNO3 (aq) + NaOH (aq) --- > NaNO3 (aq) + H2O (l) From the NaOH titre volume, the number of moles of NaOH are calculated. From the reaction above it can be noted that the ratio [ Acid : Alkali ] = 1 : 1, and thus the moles of HNO3 are half that of NaOH. 2 K3PO4 + 3 Ca(NO3)2 = 6 KNO3 + Ca3(PO4)2 BaCl2 + Na2SO4 = 2 NaCl + BaSO4.

Sau đó: HNO3 + Ag → AgNO3 + NO + H2O. ● Với Cu(NO3)2 cũng thương tự như AgNO3. ● Với CaCO3 ta có Phương pháp định tính - định lượng và Bài toán đốt cháy hợp chất hữu cơ. Bài toán định lượng CO₂ bằng dùng dịch bazơ (NaOH, Ca(OH)₂).CaCO3(s) + 2HNO3(aq) Ca(NO3)2(aq) + H2O(l) + CO2(g) However the reaction requires heating to ensure it reaches completion and hence the amount of calcium carbonate cannot be determined by titration the garden lime with the acid. Instead the technique of back titration was used. The lime is first reacted with an excess of acid and heated to release all the carbon dioxide.

There are three main steps for writing the net ionic equation for HNO3 + CaCO3 = H2O + CO2 + Ca(NO3)2 (Nitric acid + Calcium carbonate). Second, we write the states and break the soluble ionic compounds into their ions (these are the strong electrolytes with an (aq) after them).
