The chemical formula for ammonium chloride is NH4Cl. It is a compound made up of one ammonium ion (NH4+) and one chloride ion (Cl-).
you have to write... 2KI + Cl2 = 2KCl + I2
Ammonium carbonate, (NH4)2CO3 dissolves in water releasing the ammonium ion, NH4+, and carbonate ion, CO32- into solution. Both of these ions hydrolyze (react with water). The chemical equations describing the hydrolysis reactions are given. By adding these reactions one can write the overall balanced net ionic equation for the reaction that occurs when ammonium carbonate dissolves in water. Write the overall balanced net ionic equation, calculate the equilibrium constant, write the overall equilibrium expression, and calculate the carbonate ion concentration, [CO32-], of a 1.0 mol/L solution of ammonium carbonate. (Hint: this requires solving a quadratic equation)... --Equations (1) (NH4)2CO2 (aq) --> 2NH2+ + CO32- (2) NH2+ + H2O(l) <--> NH2(aq) + H2O+ Ka=5.6x10-10 (3) CO32- + H2O(l) <--> HCO3- + OH- Kb=2.1x10-4
3Cu^2+(aq) + 2PO4^3-(aq)====>Cu3(PO4)2(s)
4 LiH + AlCl3 =======> LiAlH4 + 3 LiCl
The chemical formula for ammonium chloride is NH4Cl. It is a compound made up of one ammonium ion (NH4+) and one chloride ion (Cl-).
The balanced chemical equation for the reaction between ammonium sulfate (NH4)2SO4 and barium chloride BaCl2 is: (NH4)2SO4 + BaCl2 → BaSO4 + 2 NH4Cl This reaction forms barium sulfate (BaSO4) and ammonium chloride (NH4Cl) as the products.
NH3(g) + HCl(g) ==> NH4Cl(s). This type of reaction is called "synthesis". The two gases react to form a solid ammonium chloride salt.
you have to write... 2KI + Cl2 = 2KCl + I2
The balanced equation is: 2Al(C2H3O2)3(aq) + 3(NH4)3PO4(aq) → AlPO4(s) + 6NH4C2H3O2(aq)
NH3Cl, (careful how you write it) is nothing. Although for most purposes the existence NH3Cl+ can be ignored, it does exist. It can be prepared as a salt with an appropriate cation. However it is may not be very stable. NH4Cl+ is ammonium chloride.
2KClO3 ----> 2KCl + 3O2

The chemical equation is:K2CO3 + CaCl2 = CaCO3(s) + 2 KCl
To write the formula for barium bromide (BaBr₂) as a chemical equation, you need a reaction. For instance, the reaction between barium chloride (BaCl₂) and sodium bromide (NaBr) would form barium bromide and sodium chloride (NaCl): BaCl₂ + 2NaBr → 2NaCl + BaBr₂.
The balanced chemical equation for the reaction between aluminum wire and cupric chloride is 2Al + 3CuCl2 → 3Cu + 2AlCl3. In this reaction, aluminum displaces copper from cupric chloride to form copper and aluminum chloride.
The reaction between sodium chloride (NaCl) and silver nitrate (AgNO3) results in the formation of silver chloride (AgCl) which is insoluble. Thus, the net ionic equation isAg^+(aq) + Cl^-(aq) ==> AgCl(s)
