Answer:
%H = 6.72 %
Explanation:
Percent composition of an element is the total mass of that element divided by the molecular mass of compound (or molecular mass) of which it is present in.
So,
Percent composition of Hydrogen will be given as,
%H = Total mass of H / Molecular Mass of Acetic Acid × 100
So,
Total Mass of H = 1.01 × 4 = 4.04 g
Molecular Mass of Acetic acid = 60.052 g/mol
Putting values in above formula,
%H = 4.04 g/mol ÷ 60.052 g/mol × 100
%H = 6.72 %
Answer:
Option A is correct. About 5 g of the KClO3 is dissolved
Explanation:
KClO3 is not very good soluble in water.
So, Option C is impossible, because KClO3 is poorly soluble in water.
The low solubility of KClO3 in water causes KClO3 to isolate itself from the reaction mixture by precipitating out of solution.
So, option D will either happen.There will be a part of KClO3 dissolve.
At 10 °C, KClO3 has a solubility of 4.46 g/100 gram (10 °C).
Option A is correct. About 5 g of the KClO3 is dissolved
___ is Thermal energy that flows between objects due to a difference in tempture
B Heat
Microwave it! It just has to be defrosted.
