What is reduced and what is oxidized in Cl2 plus 2NaBr - 2Br plus 2NaCl?

Oxidation is loss of electrons and reduction is gain of electrons. In this case the Cl2 molecule is changed to two Cl- ions by gaining electrons, so the Cl2 is reduced. The Br in the NaBr salt is in the form of Br- ions. The Br- ions are changed to neutral Br atoms (a Br2 molecule) by losing electrons and so are oxidised.

In the reaction FeCl2 plus 2NaOH gives iron II hydroxide plus 2NaCl 6 moles of FeCl2 are added to 6 moles of NaOH how many moles of FeCl2 would be used up in the reaction?
3 mole FeCl2 will react with 6 mole NaOH (stoechiometric mole ratio: 1 FeCl2 to 2 NaOH), so 3 mole FeCl2 (= 6 added -3 used) will be left over.
What does plus 12V mean?
Plus twelve volts if you're in physics.
In word form what is Na2CO3 plus 2 HCl gives 2 Na 2Cl plus H2O plus CO2 stand for?
Sodium carbonate plus hydrochloric acid gives sodium chloride plus water plus carbon dioxide.
What is Ni plus mgcl2?
No reaction
What is 2169 plus 3984?
it = 6153
How can your tell hat is oxidize in a redox reaction?
my reactant is Cl2 plus 2NaBr, my product is 2NaBr2. Which one is oxidized, what is reduced. How can I tell which one is which?
How do you write a balanced equation for sodium bromide plus chlorine yields sodium chloride plus bromide?
I think this is right... Cl2 + 2NaBr = 2NaCl + Br2
Is nadh oxidized or reduced compared to nad plus?
NAD+ is the oxidized and NADH is the reduced form.
How do you write Solid sodium bromide plus chlorine gas yields solid sodium chloride plus bromine gas as a balanced equation?
2NaBr (s) + Cl2 (g) --------> 2NaCl (s) + Br2 (g)
What element is oxidized and which element is reduced in the following reaction Zn plus CuSO4----ZnSO4 plus Cu?
Cu is being reduced and Zn is being oxidized, hence Zn + CuSO4 --> ZnSO4 + Cu
Is Cu oxidized or reduced in CuO plus H2 yields Cu plus H2O?
Cu is oxidized. The oxidation number goes from 0 in Cu to +2 in CuSO4. S is reduced. The oxidation number goes from +6 in H2SO4 to +4 in SO2. The oxidizing agent is H2SO4 since it causes Cu to be oxidized. The reducing agent is Cu since it causes S in H2SO4 to be reduced.
How does NAD plus get oxidized?
NAD+ isn't oxidised, it can be reduced by H to form NADH
What are the reducing and oxidizing agents of the reaction FeCl plus SnCl?
Tin and iron are being oxidized because to be oxidized is to lose electrons. Chlorine is being reduced, because it gains electrons.
What type of reaction is 2nacl plus h2so4?
2NaCl + H2SO4 = Na2SO4 + 2HCl
Complete the balance of Br2 plus NaI?
Br2 + 2NaI -> 2NaBr + I2
What type of reaction is represented in Zn plus 2NaCl yields 2Na plus ZnCl2?
The type of reaction represented by Zn plus 2NaCl yields 2Na plus ZnCl2 is an impossible one. It would be the other way around. 2Na + ZnCl2 --------> 2NaCl + Zn
What solution will correctly complete and balance this equation NiCl2 plus 2Na?
2NaCl + Ni (for A+)
