If you have 2 of the same substance and they are at the same temperature but have a different amount, what changes?
Lina20 [59]

Answer:

The heat energy stored within them changes

Explanation:

Heat energy is a function of the mass of a body, its specific heat capacity, and its temperature.

In this case, the bodies have the same specific heat capacity since they are made from the same material and the same temperature.

To get the quantity of heat stored in a body, we need to multiply all three parameters as shown below

Q = mC \Delta T

An increase in mass, through an increase in the amount of substance of a material present, will cause a corresponding increase in the heat energy stored within the material

How many grams of nitric acid will react completely with a block of iron metal that is 4.5 cm by 3.0 cm by 3.5 cm, if the densit
denpristay [2]

Balance the equation first: 

2 Fe+6 HNO3→2 Fe(NO3)3+3H2

Then calculate mass of Iron :

4.5×3.0×3.5 cm3(1 mL1 cm3)(7.87 g Fe1 ml)=371.86 g Fe

Now use Stoichiometry:

371.86 g Fe×(1 mol Fe55.85 g Fe)×(6 mol HNO32 mol Fe)=19.97 mol HNO3

Convert moles of nitric acid to grams

19.97 mol HNO3×(63.01 g HNO31 mol HNO3)=1258.3 g HNO3
