Balance the following equation: Na(s)+CL2(g)---->NaCL(s)?
2Na(s)+CL2(g)---->2NaCL(s) ok? having fun?
How do I balance this equation please, CaCl2 + Na2CO3 = CaCO3 + NaCl?
CaCl2 (aq) + Na2CO3 (aq) ----> 2 NaCl(aq) + CaCO 3(s) 1 mole of calcium chloride + 1 mole of sodium carbonate yields 2 moles of sodium chloride + 1 mole of calcium carbonate In the beginning, there were calcium ions, chloride ions, sodium ions, and carbonate ions, all floating around in the solution. But when a calcium ion finds a carbonate ion, they stick together forming an insoluble precipitate, calcium carbonate. The sodium ions and chloride ions remain in solution. http://cavemanchemistry.com/oldcave/projects/rxn.1/index.html
Which is a balanced equation? Na + Cl --> 2 NaCl / Na + Cl2 --> 2 NaCl or 2 Na + Cl2 --> 2 NaCl?
2Na + Cl2 --> 2NaCl is the correct choice. Notice there is 2 Na's and 2 Cl's on the reactants side of the arrow and on the products side there are also 2 Na's and 2 Cl's- therefore the equation is balanced.
How do I complete and balance an equation for reaction of hydrochloric acid (HCl) with sodium hydroxide (NaOH)?
(2)HCl + (2)NaOH→ (2)NaCl + (2)H2OH total left = 4, Cl total left = 2, Na total left = 2, O total left = 2H total right = 4, Cl total right = 2, Na total right = 2 O total right = 2first balance the Cl and Na, then hydrogens, then oxygens. always balance the oxygens last.total = 8
Balancing Equations?
1. C3H8+O2 = CO2 + H2O You have on the first side : 3C, 8H and 2O On the other side : 1C, 3O and 2H You need to have the same number of each atom on both sides. To get the same number of H, you must add 3(H2O) : C3H8 + O2 = CO2 + 4H2O Now : 3C, 8H, 2O = 1C, 8H, 4O You can then add 2(CO2) to balance C : C3H8 + O2 = 3(CO2) + 4(H2O) Now : 3C, 8H, 2O = 3C, 8H, 10O Finally, you have to add 4(O2) to get both sides balanced. C3H8 + 5(O2) = 3(CO2) + 4(H2O) 2. Na + Cl2 = NaCl Adding one NaCl will balance for the Cl, then you add one Na to get everything balanced : 2(Na) + Cl2 = 2(NaCl) 2Na, 2Cl = 2Na, 2Cl 3. H2O2 = H2O = O2 I guess you mean : H2O2 = H2O + O2 We have : 2H, 2O = 2H, 3O If you add 2(H2O2), you have to possibility to balance things: 3(H2O2) = 3(H2O) + 1.5(O2) For : 6H, 6O = 6H, 6O Now you can multiply both sides by 2 to get integer coefficients : 6(H2O2) = 6(H2O) + 3(O2) 4. CH4 + O2 = CO2 + H2O 1C, 4H, 2O = 1C, 2H, 3O Lets add 1(H2O) to begin by balancing H : CH4 + O2 = CO2 + 2(H2O) 1C, 4H, 2O = 1C, 4H, 4O Adding 1(O2) will balance the O : CH4 + 2(O2) = CO2 + 2(H2O) 1C, 4H, 4O = 1C, 4H, 4O 5. Li + H2O = LiOH + H2O I guess you mean : Li + H2O = LiOH + H2 If so, we add a H2O first because we're missing a H anyway on the left part : Li + 2(H2O) = LiOH + H2 1Li, 4H, 2O = 1Li, 3H, 1O Now, by adding a LiOH, we have the O and H balanced at once and we just have to add a Li on the other side to get the whole thing good : 2(Li) + 2(H2O) = 2(LiOH) + H2 2Li, 4H, 2O = 2Li, 4H, 2O Hope you observe the method and this helps!

Which of the following equations is balanced?
Which of the following equations is balanced? Na + Cl2 NaCl 2Na + Cl2 NaCl Na + 2Cl2 2NaCl 2Na + Cl2 2NaCl 2. Why must chemical equations be balanced? to represent conservation of energy to represent conservation of mass to show that sometimes the amounts of atoms vary to make the chemical reaction work as planned 3. Which of the following is the balanced equation for P + O2 P2O5? 4P + O2 2P2O 4P + 5O2 P2O5 P + 5O2 2P2O5 4P + 5O2 2P2O5 4. Which of the following shows the balanced equation for Ca + O2 CaO? 2Ca + O2 2CaO 2Ca + 2O2 2CaO Ca + O2 CaO 4Ca + 2O2 2CaO 5. The equation 2NaNO3 + CaCl2 2NaCl + Ca(NO3)2 is balanced. How many atoms of oxygen are there on each side of the equation? 2 3 6 8
How do you write the balanced chemical reaction equation for Na2CO3 + NaCL?
NaCl + Na2CO3 → 3Na^+ + Cl^- + CO3^-2Essentially there is no reaction. Sodium chloride dissolves in water as sodium cations and chlorine anions. Sodium bicarbonate dissolves to form again sodium ions and bicarbonate ions. Chlorine and bicarbonate will not react.The bicarbonate ion will react with water molecules by taking protons from water and increasing hydroxide ion concentration which will make the pH > 7:CO3^-2 + H2O < - -> HCO3^- + OH^-HCO3^- + H2O <- -> H2CO3 + OH^-
Which of the following equations is balanced? please!!?
I believe it's F
Why is [math]NaOH + HCl \rightarrow NaCl + H2O[/math] a balanced equation?
By balanced we just mean that the number of each type of atom on each side is the same!So we have 1 Na, 1 O, 2 H, and 1 Cl on each side - so it is balanced!But [math]NaOH + HCL -> NaCl + 2 H_2O[/math] is not balanced!
