How do you balance #Al + F_2 -> AlF_3#?

Answer 1

To balance the chemical equation Al + F₂ → AlF₃, you need to put a coefficient of 2 in front of AlF₃. This will give you 2 Al atoms on both sides of the equation and 6 F atoms on the reactant side and 6 F atoms on the product side, thus balancing the equation. The balanced equation is: 2Al + 3F₂ → 2AlF₃.

#Al + F_2 rarrAlF_3# here F is unbalanced : on right hand side(product side) there are 3 F and on the left hand side there is 2F

Utilize the L.C.M. of the two numbers to achieve balance on both sides; in this case, L.C.M. of (2,3)=6, so we aim for six F on both sides.

#Al + 3F_2 rarr 2AlF_3# now we need to balance Al #2Al +3F_2 rarr2AlF_3#

You balance it stoichiometrically: GARBAGE IN MUST EQUAL GARBAGE OUT.

Mass and charge are always conserved in a chemical reaction:

#2Al(s) + 3F_2(g) rarr 2AlF_3(s)#.

If you must perform calculations using this formula, you could write the following to make things a little bit simpler for yourself: Is mass conserved in this representation? How?

#Al(s) + 3/2F_2(g) rarr AlF_3(s)#

What does #1/2F_2(g)# represent in #"grams"#?

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
