No, it's Ag2S. The 2 is a subscript, denoting 2 Silver atoms to 1 Sulphur atom. Silver has a valency of 1+, while Sulpur has a valency of 2-, hence 2 Silver atoms are needed to balance with 1 Sulphur atom to form a compound. Besides, the equation would make sense then. 2 Silver atoms and 1 Sulphur atom on both sides of the equation, the equation is now balanced. 10 marks please, thank you!

Here is a great site, made specially for teachers, that has many tutorials, plus links to others\n\nGood luck\nhttp://sciencepage.org/chem.htm

NaCl2 + NaCO3 ==> NaCO3 + NaCl2 NOTE: these two reactants will not react because the reactants and the products are identical\n\nCu + O2 ==> CuO2   This is already balenced\nCuSO3 + Fe ==> FeSO3 + Cu   The charge is not given so procuts could be different\n\n2HCl + 2Zn ==> 2ZnCl + H2\nMnO2 + H2O2 ==> No reaction: similar to NaCl2+NaCo3\n\nGood luck

You need to make sure that there is the same number and kind of atoms on each side of the arrow.\n\nCa(OH)2 + MgCl2 ---> Mg(OH)2 + CaCl2, both Mg and Ca stay+2\n\nBaO2(s) + H2SO4 ---> BaSO4(s) +H2O2 \n\nAg2S --->2 Ag+  +  S-2\n\nHC2H3O2 + MgCO3 (s) ---> H2O + CO2 + Mg+C2H302-\n\nI may not have written net ionic form, but I did get all the atoms on each side I am unsure of the reaction producing hydrogen peroxide, but you do have to account for all atoms.

Concept: An element and a compound can react to form another element and another compound. \n\nMaterials: 200 mL of 0.1M copper(II) chloride (CuC12), 5 cm. square piece of aluminum foil (Al), 400-mL beaker, safety goggles. \n\nProcedure: 1. Place the beaker of copper(II) chloride in front of the class. 2. Crumple the aluminum foil and throw it in the beaker. 3. Soon the solution starts to bubble as hydrogen gas is produced. 4. A red brown precipitate of copper falls to the bottom of the beaker, and the aluminum foil dissolves completely. 5. Aluminum would react spontaneously with water without its protective oxide coating. The aluminum-copper(II) chloride reaction removes this protection. Caution: Copper(II) chloride is an irritant. \n3CuCl2 + 2Al --> 2AlCl3 + 3Cu\n\nInput = 3CuCl2 + 2Al \nOutput = 2AlCl3 + 3Cu

This is a addition-elimination reaction (http://www.chem.ucalgary.ca/courses/351/Carey/Ch23/ch23-3-3.html). can be accelerated by lewis acids.

C3H7NO2 \n\nwww.chemfinder.com is a useful resource.  \n\nI hope this helps :)

You are looking at a displacement reaction, in which the more reactive metal (Cu) is displacing the less reactive metal (Ag) from its salt solution (AgNO3).\nCu (s) + 2AgNO3 (aq) --> 2Ag (s) + Cu(NO3)2 (aq)\n\nHope this helps. :)

It is not a reaction because the bond formed is ionic, not covalent.  Extraction is a better term for the process you are describing.

ask your chem prof or tutor ..it's hard to explain over the internet!

1. AgCl(s) + NaNO3\n\n2. AgOH(s) + NaNO3\n\n3. They would not react as both are nitrates already

NH4OH + CH3COOH -> CH3COO-NH4+ + H2O\n\nNot all acid-base reactions form salts.
