<span>The
energy that was produced is called, heat combustion. It is an energy released
in the form of heat when chemicals are mixed. An explosion of light and sound
are the common characteristics of heat combustion. The chemical reaction takes
place because of the presence of oxygen and hydrocarbon or organic molecule
substances that when mixed form carbon dioxide and water which then releases
heat and explosive characteristics.</span>
A mineral ranked higher in the mohs scale is relatively harder than other minerals. Mohs scale lists 10 minerals from the softest to hardest. The hardest mineral is diamon while the softest one is talc. The two minerals compared are scratched with each other. The scratched one is the softer mineral.
Answer:
36.08%
Explanation:
We are given the overall formula of the compound as: CuSO4•5H2O
Now, atomic mass of the elements are;
Cu = 63.55 g/mol
S = 32.07 g/mol
O = 16 g/mol
H20 = 18.02 g/mol
Now, let's calculate the total mass of the compound:
(63.55 g/mol) + (32.07 g/mol) + 4(16 g/mol) + 5(18.02 g /mol) = 249.72 g/mol
From the above, water in the compound is 5(H20)
Thus, total water atomic mass = 5 × 18.02 = 90.1 g/mol
Thus, percentage of water = (atomic mass of water/total mass of compound) × 100%
Percentage of water = (90.1/249.72) × 100% = 36.08%
It might calculate the volume, but you need the length as well, depending on the object.
