Answer:
You are given:
4Fe+3O_2 -> 2Fe_2O_3
4:Fe:4
6:O_2:6
You actually have the same number of Fe on both sides, The same is true for O_2 so yes this equation is properly balanced.
For added benefit consider the following equation:
CH_4+O_2-> CO_2+2H_2O
ASK: Is this equation balanced? Quick answer: No
ASK: So how do we know and how do we then balance it?
DO: Count the number of each atom type you have on each side of the equation:
1:C:1
4:H:4
2:O:4
As you can see everything is balanced except for O To balance O we can simply add a coefficient of 2 in front of O_2 on the left side which would result in 4 O atoms:
CH_4+color(red)(2)O_2-> CO_2+2H_2O
1:C:1
4:H:4
4:O:4
Everything is now balanced.

all real numbers
Step-by-step explanation:
(f(x) g(x)) = 
= 
via FOIL
The two lines are perpendicular because both of the lines intersects

Here is the answer to the problem above. Given that the recipe only calls for 2 and 1/2 cups and this is for one batch only, and Dan used 6 and 1/4 cups, we will solve how many batches of pita bread he made by dividing 6 and 1/4 by 2 and 1/2. So this would be 25/4 divided by 5/2. So the result is 2 and 1/2. So the number of batches of Pita bread he made is 2 and 1/2 batches. Hope this answer helps.
