It means that the fit and well adjusted ones thrive and "make it", and the weak ones that can't adapt die.
Options:
- NaOH(aq)
- NaOH(l)
- N2(g)
- NO(g)
Answer: <em>NaOH (aq)</em>
Explanation:
Defining state terminologies, '<em>aq' </em>means aqueous, meaning the analyte is in solution, as opposed to gaseous (g), or liquid (l).
Answer: HA + H2O ⇌ H3O+ + H- (option #4)
Explanation: Since the acid is weak you have to use a ⇌ (equilibrium) sign. Equilibrium is denoted in a chemical equation by the ⇌ symbol. Also, when any acid dissolves into water, it produces hydronium (H3O+ or H+). Therefore, the fourth chemical reaction is your answer.
Your question, I guess, How do vapour and gases differ...
Answer:
1.) Vapour is the changed state of any liquid either due to boiling or evaporation
2.) Vapour are more energetic as they have absorbed the latent heat of vaporization whereas Gases are low in energy because they are already in gaseous form at room temperature.
3.) Vapour have boiling points above room temperature while gases have their boiling point below room temperature.
