Since no reaction creates or destroys atoms, every balanced
chemical equation must have equal numbers of atoms of each element on each side
of the equation. However, the number of molecules does not necessarily have to
be the same.
The answer is
No, the total number of molecules can be equal or not

Answer:
2640 feet
Step-by-step explanation:
Let's make a proportion using this:
feet/seconds=feet/seconds
We know the car travels 88 feet in 2 seconds.
88/2=feet/seconds
We don't know how many feet the car can travel in 1 minute (which is equal to 60 seconds).So, the car travels x feet in 60 seconds.
88/2=x/60
We want to solve for x. To do this, we have to get x by itself. x is being divided by 60. Multiply both sides by 60, because multiplication is the opposite of division.
60*88/2=x/60*60
The 60s on the right will cancel, so we are left with
60*88/2=x
60*44=x
2640=x
The car can travel 2640 feet in 1 minute.
