Answer:
1.242 g/mL
Explanation:
Step 1: Given data
Mass of the empty container (m₁): 80.21 g
Mass of the filled container (m₂): 105.22 g
Volume of the unknown liquid (V): 20.14 mL
Step 2: Calculate the mass of the liquid
The mass of the liquid is equal to the difference between the mass of the filled container and the mass of the empty container.
Step 3: Calculate the density of the unknown liquid
The density of the liquid is equal to its mass divided by its volume.
C-12? (6 protons) C-13? (6 protons) C-14? (6 protons)
CaCl2(aq) + K2CO3(aq) → 2 KCl(aq) + CaCO3(aq)
1.12 g
2.23 g
0.896 g
4.47 g
1.12 g

Answer:
D. Different functional groups and different physical and chemical properties
Explanation:
A functional group is an atom or group of atoms within a molecule that determines the chemical and physical properties of the compounds it appears in.
The functional group of an alcohol is the -OH group while that of an ether is an oxygen atom bonded to two alkyl or aryl groups, R-O-R'.
Based on the above;
Option A is wrong because they have different functional groups, hence different properties
Option B is wrong because they don't have same functional group even though their properties are different
Option C is wrong because they have different properties even though they have different functional groups
Option D is correct because they have different functional groups and different properties.
