1. Write down the cations and anions present in each of the reactants. You'll have to have memorized a list of common ions to do this! In this case, the NiCl2 contains Ni2+ and Cl-, and the (NH4)2S contains NH4+ and S2-. Tables of common monatomic ions and polyatomic ions can be found elsewhere on this site. 2. Swap the ions to build the products. The Ni2+ will pair up with the S2- to produce NiS. The NH4+ and the Cl- will produce NH4Cl. Make sure that you combine the cations and anions so that the charges balance. 3. Label the products as solid, liquid, or aqueous. In general, you'll have to have memorized the solubility guidelines, or looked up the solubilities of the products in a handbook to do this. In this case, because sulfides of metals that are not alkali metals are insoluble, write the NiS as a solid, and the NH4Cl as an aqueous (dissolved) salt. 4. Does a reaction occur? If one of the products is not a weak electrolyte, a nonelectrolyte, or a solid, no reaction occurs. In this case, NiS is a solid, so a reaction does occur. 5 Balance the equation. Change the coefficients in front of each compound in the equation so that you have the same number of each type of atom on each side of the equation. thas how you can predict if is going to reactants.
1. Write a sentence to describe the reaction including the names and states of all reactants and products where the charges on particles and polyatomic ions indicates that the ionic compounds have a cation and anion.
2. Then separate the reactants and products with process symbols stating that the reaction goes to completion, the reaction is reversible at equilbrium (reaction and prodcuts are mixed), and net reaction.
3. Replace the names for formulas by putting these plus signs between formulas.
4. Then include symbols to indicate for the physical state by including (g)gase, (l) liquid, (s) solid, and (aq) aqueous that dissolves in water.
5. Make sure that the equation is balanced by adding coefficents so the atoms and charges are conserved. Each side should include the same number of atoms of each type, and the same total charge.
Like for example, synethesis may have 1 element or compound that will become the cation and the other reactant will be the anion. Ca + Cl2 --> CaCl2
Another example could be double displacement where 2 cations and 2 anions will take the place of each other on 2 different compounds. The ion does exactly remain the same. NaCl + Pb(NO3)2 --> PbCl2 + NaNO3
Overall, this is a way how you will be able predict products if the reactants are known.

The focus of the question is how to predict products if you are known the reactants. I do not know how 11 students' response is about how to write a chemical equation from a sentence that is talking about reaction. You need to respond again focusing on how to predict the products.
If the products are unknown and the reactants are you could predict the products by... *First write down the elments and or the compounds listed in the reactants. *Then identify the elments and compounds -such as NCl that would be nitrogen chloride *After you have done that you will be able to predict what the products are. Be sure to check the coefficents of the reactants, to make sure that the equation is balanced...Note that you can not change anything in the reactants because they are already given and changing anything would change the products and possibly the reaction, so change the product coefficents.:]
A way to predict a product in a reaction would be to predict the element(s) that each compound is most likely to bond to. After you make your predictions you should have an idea on the possible product that will be created.
If the products are unknown and the reactants are present, it can predicted by these steps.
Look for the obvious precipitation reactions, two aqueous salt solutions that is mixed together with one of the salts contains an ion that is often insoluble (such as Fe, Ba, Ag, Hg, Pb).
2. Look for other possible precipitation reactions in which one of the above ions is present in an aqueous sakt but the other solution is the acid that might provide an anion (like sulfate or chloride) that could be present.
Next, identify easy acid/base reactions in which you have an easily identifiable acid (nitric, sulfuric, hydrochloric) and a hydroxide salt as the base.
Look for easily identifiable redox reactions in which 02 is a reactant and an oxidizing agent with the other reagent is a hydrocarbon, a carbohydrate, a metal, etc. The hydrocarbon and carbohydrate will react to form oxides.
Look for other redox reactions, such as when you have a pure metal interacting with a ion of another metal or an acid which can dissolve it to form a salt of metal.
To predict the unknown product of known reactants in a chemical reaction, first, write down the cations and anions present in each reactants. Next, swap the ions to build the products. Then, label the products in their state of matter (solid, liquid, or aqueous). If one of the products is not a weak electrolyte, a nonelectrolyte, or solid, no reaction occurs. The last step, balance the equation. Change the coefficicients in front of each compund in the equation so that the same number of each type of atom is equal on each side of the equation.
you can predict a product by just looking at it. first you pay attention to if there are any diatomic particles and if not their are compounds. You can tell what type of reaction it is depending on what it starts off with, in that case how many compounds it starts with. of course anions and cation always switch with its match so that means and they pair with their opposite.
