Which of the following statements about gases is not correct? A. They have much lower densities than solids or liquids. B. They
form homogenous mixtures regardless of the nature of gases. C. They have strong intermolecular forces causing the particles to cling together. D. They have high compressibility. E. They do not possess a shape of their own.
C. They have stong intermolecular forces causing the particles to cling together.
Explanation:
Have you ever seen images where gases are all spread out and floating around? Well if you have, this is because the intermolecular forces are weak and are spreak apart. Contrary to this incorrect statement, solids have the stongest intermolecular force and cling together.
Given the equilibrium reaction: 2 A (aq) + 3 B (aq) <— —> 2 C (aq) + D (aq) and equilibrium concentrations of [A] = 0.60M, [B] = 0.30 M, [C] = 0.10 M and [D] = 0.50 M. The Kc value will be: a. 1.9 c. 2.4 b. 0.15 d. 0.51
Growth rate calculations and their conclusions can be used in biomedical contexts when organisms are being grown for the synthesis of compounds or other purposes.
