Which substance will have the largest temperature change if the same amount of heat is added to each of them? ethanol, c2h5oh(l) water, h2o(l) aluminum, al(s) iron, fe(s)?

Option (d) is the correct answer.

Explanation:

Specific heat is defined as the amount of heat necessary to raise the temperature of a unit mass of substance.

Relation between heat energy, specific heat and temperature change is as follows.

                            q =

where,       q = heat energy

                  m = mass

                  C = specific heat

              = change in temperature

Specific heat of ethanol is 2.46 , water is 4.18 , Al is 0.902, and Fe is 0.450 ,  

As specific heat is inversely proportional to change in temperature. Therefore, smaller is the value of specific heat more will be the change in temperature.

So, when mass of all the given species is constant. Then change in temperature of iron (Fe) will be the largest because it has the least value of specific heat.

Thus, we can conclude that out of the given options iron (Fe) will have the largest temperature change if the same amount of heat is added to each of them.

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 !
