9. You have a balloon with a volume of 2 liters when you hold it in the air at 1 atmosphere of pressure. If you take it into a swimming pool and hold it below the
water. If you take the balloon down to the bottom of a deep swimming pool at
about 16 feet the atmospheric pressure goes to 1.5 atmosphere. What will
become the new volume of the balloon as the water presses in on it?

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 !

the ratio of the conjugate base to the acid required to attain the desired ph.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
