What is the balanced equation of phosphoric acid and zinc hydroxide?
phosphoric acid H3PO4 sodium hydroxide NaOH H3PO4 + 3NaOH = Na3PO4 + 3H2O 1 acid + 3 base = 1 salt + 3 water
What is the product of Zn plus HNO3?
Zinc and Nitric acid react to produce Zinc nitrate, Water and Nitrogen Mono Oxide if the Nitric acid is Dilute... 3Zn + 8HNO3 = 3Zn[No3]2 + 4H20 + 2NO
What is the correct cell notation for the reaction 3Zn2 plus aq plus 2Als equals 2Al3 plus aq plus 3Zn s?
Al(s) | Al3+(aq) Zn2+(aq) | Zn(s)
A reaction between solid zinc and aqueous gold III nitrate?
3Zn(s) + 2Au(NO3)3(aq) ---- 3Zn(NO3)2(aq) + 2Au(s)
Finish balancing the following equation Al(s) plus 3Zn(NO3)2(aq) Al(NO3)3(aq) plus Zn(s) What coefficient does Al(s) have in the balanced equation?
the answer is 2 apex
Zinc reacts with iron chloride yielding zinc chloride plus iron precipitate?
Zn + FeCl2 ------> ZnCl2 + Fe (for Iron(II) ) or 3Zn + 2FeCl3 ------> 3ZnCl2 + 2Fe (for Iron(III) )
What is the balanced equation for zinc metal and nitric acid reaction?
In hot concentrated acid, nitric is an oxidizing acid: 3Zn + 8HNO3 → 3Zn(NO3)2 + 2NO + 4H2O But in cold, dilute solutions: Zn(s) + 2HNO3 (aq) → Zn(NO3)2 (aq) + H2 (g)
Finish balancing the following equation:__Al(s)+3Zn(NO 3 )2(aq) ➝ Al(NO 3)3(aq)+__Zn(s) What coefficient does Al(s) have in the balanced equation?
2
What is the chemical equation for zinc hydroxide solution completely reacts phosphoric acid solution?
Zinc (II) = Zn+2Hydroxide = OH-So Zinc Hydroxide = Zn(OH)2Hydrogen =H+ Phosphate = PO4-3So Hydrogen Phosphate = H3PO4So Zn(OH)2 + H3PO4 ---> Zn3(PO4)2 + H2O is the initial equation, but you need to balance it before you can do anything with it, that means that you need an equal amount of each element on each side of the equation.3 Zn(OH)2 + 2 H3PO4 ---> Zn3(PO4)2 + 6H2OIts easy to check the equation to make sure its balanced, just count your elements on each side of the arrow3Zn + 12H + 6O + 2PO4 on each side of the equation, and its balanced.
How do you balance the equation when zinc reacts with iron III chloride yielding zinc II chloride plus iron precipitate?
Write what you have first, Zn + FeCl3 ---> ZnCl2 + Fe Everything matches up except the Cl, we have 3 on the left and 2 on the right. To balance, we look for a common factor, which is 6. So we multiply the FeCl3 by 2 and the ZnCl2 by 3. Zn + 2FeCl3 ---> 3ZnCl2 + Fe Now we have 6 Cl on both sides but the Zn and Fe are unbalanced. Now we have 2 Fe on the left and 1 on the right. We have 1 Zn on the left and 3 on the right. So we multiply the reactant Zn by 3 and the product Fe by 2. 3Zn + 2FeCl3 ---> 3ZnCl2 + 2Fe Zn Zn Zn + ClFeCl ClFeCl ---> ClZnCl ClZnCl ClZnCl + Fe Fe Cl Cl 3 Zn, 6 Cl, 2 Fe ---> 6 Cl, 3 Zn, 2 Fe The same amount of each atom is on each side so it's balanced.
Will be there a reaction if aluminum is dipped into zinc nitrate solution?
Yes, Al is more reactive than Zn, so: 2Al + 3Zn2+ --> 2Al3+ + 3Zn (Nitrate ions are tribuned out of this reaction)
What is the word equation for the reduction of zinc?
3Zn(s) + Fe2(SO4)3(aq) -----> 3ZnSO4(aq) + 2Fe(s) Zinc will displace iron from its salt solution as it is more reactive....
