Arocket car accelerates uniformly from rest at and reaches maximum velocity of 150 m/s through a distance of 510 m, the boosters turn off and the rocket coasts to a stop in 22 seconds (this time is from the moment the boosters are turned off)
what is the acceleration while the boosters are on?
how far does the booster coast from the moment the boosters are turned off?
what is the average velocity of the whole trip?

how to make a simple air condition

2fe + 3h2so4 -> fe2(so4)3 + 3h2

it is necessary to balance equations in order to get the proper amount of reactants as well as products in order not to make a miscalculation.

you cannot change the subscripts as that would change the substance itself. for instance, diatomic elements such as h2 only have the subscript two when a gas. another example would be so4, if you were to change the subscript, the element would no longer be sulfate.

we change the coefficients instead as that only changes the number of molecules rather than the substance itself.

hope this !

it is b that is the answer.
