A piece of an unknown metal is placed in a coffee cup calorimeter as shown below in order to determine its specific heat. Data was collected and is shown in the table below. Sketch a graph of temperature vs. time for both the metal and the water.
Label on your graph the point at which thermal equilibrium has been established.
Use the information in the data table to calculate the specific heat of the metal.

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 !
