The temperature of a 6.0 g sample of glass change from 20 degrees celsius to 45 degrees celsius when it absorbs 550 j of heat what is this specific heat of this glass sample

The specific heat of a substance measures the energy required to raise the temperature of a one-unit-mass sample of this substance by one unit.

The question provides the following information:

The specific heat of this substance measures the energy change for a process involving:

Apply the formula

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 correct answer would be d. hope this !
