Answer:
A.
4Fe + 3O2 2Fe2O3 .........................
Answer:
8 quarters
Explanation:
Let's look at the ratio first off.
2 quarters: 4 dimes: 7 nickels
Let's write it in terms of money
50 cents of quarters: 40 cents of dimes: 35 cents of nickels
If we add up all the cents then we get $1.25
Then, if we divide $5 by $1.25 we get 4.
You should then multiply the original ratio by 4:
8 quarters: 16 dimes: 28 nickels
Let's check this by turning it to money:
$2: $1.60: $1.4
This all adds up to $5
Therefore your answer is 8 quarters.
