Answer:H2+Br2-->2HBr
Step-by-step explanation:
The amount of atoms on the left side must be equal to the amount of atoms on the right side for each element.
On the left you got 2xH and 2xBr.
This means you must have the same amount on the right.
2HBr =2xH + 2xBr
1 foot = 12 inches.
0.75 feet x 12 inches per foot = 9 inches per day.
1 day = 24 hours.
9 inches / 24 hours = 0.375 inches per hour ( 3/8 inch per hour)
