Answer:
The fatty acids and glycerol contributes to soap’s slippery texture.
Explanation:
- What we need to know is that every oil has a specific index for strength, cleaning, etc.
- All of them are determined by the amount of certain fatty acid in the oil.
- When we make soap, what we need to know is that oil has a special role to play in that soap.
- So for example some of those oils are used to make bubble soap or creamy soap.
- On the other side, there are some oils which are giving strength to soap.
Correct answer: C) 1.6 g
Molarity is the moles of solute present per liter solution.
The given molarity of the solution is 0.01 M.
Volume of the solution = 1 L
Calculating the moles from molarity and volume:
Converting moles to mass of copper sulfate:
Atomic radius decreases across a period because valence electrons are being added to the same energy level at the same time the nucleus is increasing in protons. The increase in nuclear charge attracts the electrons more strongly, pulling them closer to the nucleus.
