Answer:
Van't Hoff factor for AlCl₃ = 3 (Approx)
Explanation:
Given:
Number of observed particular = 1.79 M
Number of theoretical particular = 0.56 M
Find:
Van't Hoff factor for AlCl₃
Computation:
Van't Hoff factor for AlCl₃ = Number of observed particular / Number of theoretical particular
Van't Hoff factor for AlCl₃ = 1.79 M / 0.56 M
Van't Hoff factor for AlCl₃ = 3.19
Van't Hoff factor for AlCl₃ = 3 (Approx)
Answer:
A weak acid is an acid that partially dissociates into its ions in an aqueous solution or water. In contrast, a strong acid fully dissociates into its ions in water. At the same concentration, weak acids have a higher pH value than strong acids.
Explanation:
:)
Answer: No.
Explanation: Clay is filled with minerals that often weather to create shale. Clay is usually found in muddy environments, so it traps.
Answer:
B. It is important that people are not harmed for the sake of science.
Explanation:
Ethical principles stress the need to do good and cause no harm.A researcher is therefore required to;
- obtain an informed consent from the participants
- minimize or eliminate risk of harm to participants
- protect the anonymity and confidentiality of participants
- Apply no deceptive techniques
- allow the right to withdraw from the study by a participant
