How to write a balanced equation for the following reaction in acid solution?
Q. O2 + Br-1 --> H2O + Br2 I know you have to write half reactions and then balance them inorder to write an overall balanced equation, but im having trouble writing the half reactions. Any and ALL help would be great! Ca + Cr2O7-2 --> Ca+2 + Cr+3 -the same for this equation!

How would you explain the answer in the following balanced equation?
Q. 500 ml of a 0.300 mol/L sodium sulfide solution is mixed with excess copper (I) chloride, CuCl, solution I read that the balanced chemical equation for this is Na2S + 2CuCl >> Cu2S + 2 NaCl. Could somebody explain why you would write Na2S instead of NaS as the reactant and also why it is 2CuCl instead of CuCL. Please explain the first step into thinking of what to write as the reactants.
Asked by Jada - Sat Jan 12 15:28:48 2008 - - 2 Answers - 0 Comments

A. Na is in the first column and will always have a +1 charge, Cl in the 2nd to last column and will always have a -1. cu(I) means that copper is +1 and since Na2S is a reactant, that means that it has to be a -2 to make the intial reactant stable. the S gains one electron from each Na and makes its outer shell full. S is -2 so that it can have 8 outer electron. treat S just like you would O. they are in the same column. hydrogen is just like Na in the fact that it wants to lose one electron. water H2O forms just like Na2S. they lose electrons to gain them to make a full outer shell of 8 electrons. you have to make each side equal zero and you cant lose atoms. if you have 2 on the left there has to be two on the right. that is… [cont.]

Asked by Jess - Thu Jun 1 22:30:58 2006 - - 6 Answers - 0 Comments

A. Pennies are generally Zinc with a Copper Coating. Copper will not react with Hydrochloric acid (HCl), but Zinc will...very easily. The reaction is as follows, Zn (s) + 2 HCl (aq) --> ZnCl2 (aq) + H2 (g) Zinc Chloride and Hydrogen gas are produced in the reaction between Zinc metal and Hydrochloric acid.

A. The balance oxidation equation is: 2 C5H12O + 15 O2 --> 10 CO2 + 12 H2O Balancing hydrocarbon oxidation equations is tricky. It's pretty much trial and error until you have an equal number of atoms on both sides of the equation.

A. Pb(NO3)2(aq) + 2KCl(aq) --> PbCl2(s) + 2KNO3(aq) double replacement This is a "limiting reactant" question. Use each mass to compute the mass of PbCl2 as if each was the limiting reactant. The actual mass of PbCl2 produced will be the smaller of the two calculations. 5.25 g Pb(NO3)2 x (1 mol Pb(NO3)2 / 331.2 g Pb(NO3)2 x (1 mole PbCl2 / 1 mol Pb(NO3)2 x (278.2 g PbCl2 / 1 mol PbCl2) = 4.41 g PbCl2 6.45 g KCl x (1 mol KCl / 74.6 g KCl) x (1 mol PbCl2 / 2 mol KCl) x (278.2 g PbCl2 / 1 mol PbCl2) = 12.0 g PbCl2 The actual amount of PbCl2 formed will be 4.41 grams.
