Can someone help me learn how to balance equations; for instance: Na + Cl2 > NaCl?

Question

please use detailed explanation so that i can understand it

Answer 1

Well when you balance an equation, you can only add coefficients, meaning a number before the reactant.

For Na + Cl2 > NaCl , you have 2 chlorines on one side so you need 2 on the other, so you will add a 2.
Na + Cl2 > 2NaCl
Notice you cant add a 2 inbetween the NaCl because they are together. Now there are also 2 sodiums, so add another 2 infront of Na.

2Na + Cl2 > 2NaCl
There you go!! :)

Answer 2

The trick to balancing equations is to use the most complicated and oftentimes largest molecule as the starting point and remember that you can only place coeficcients in front of the entire molecular formula, not how many atoms of each substance are in the molecule itself. For example, since you have elemental Na and Cl2 on one side of the equation, you could easily just put any coefficient you want to in front of them without throwing any other elements out of whack. So start this by looking at NaCl. There is only one of these molecules, so you have one Na and one Cl. On your reactants side, you have 1 Na, that's good, but there is also one molecule of Cl2, which has 2 Cl atoms. Therefore, since you can't change the NaCl on the product side into NaCl2, because that is not how the equation works, you need to place a 2 in front, giving 2NaCl. Now you have 2 Cl atoms on both sides, but the product side now also has 2 Na where reactant side has only 1. This is easily fixed though since you saved the simplest for last, and you can just put a 2 in front of the reactant side's Na. There, 2 of each atom on each side, all balanced.

Answer 3

first element you ought to look for is diatomic molecules (the effortless thank you to undergo in ideas which those are is a rhyme: I deliver Clay For Our New domicile - Iodine, Bromine, Chlorine, Flourine, Oxygen, Nitrogen) Chlorine is on your equation so so you might hace a Cl2 - no longer 2 Cl for it to be balanced, then you definately purely make confident that the two factors have equivalent numbers of Na and Cl and basically the final one is suitable.

Answer 4

the answer is 2Na+Cl2>2NaCl

The way you do it break it down
you have 1Na and 2 Cl
The other side has 1Na and 1Cl
You have to make them equal
so here is what you have
1 Na+2Cl>1Na1Cl
Try it out

Answer 5

2Na+Cl2=2NaCl
