Answer:
Kb = [OH⁻] . [C₃H₉NH⁺] / [ C₃H₉N ]
Explanation:
The equation for the reaction of trimethylamine when it is dissolved in water is:
C₃H₉N + H₂O ⇄ C₃H₉NH⁺ + OH⁻ Kb
1 mol of trimethylamine catches a proton from the water in order to produce trimethylamonium.
It is a base, because it give OH⁻ to the medium
Expression for Kb (Molar concentration)
Kb = [OH⁻] . [C₃H₉NH⁺] / [ C₃H₉N ]
Answer: The answer is C
Explanation:the salt fits the definition of a mineral because it's a naturally occurring compound that has a definite composition and a crystalline structure. It has a crystalline structure because of its repeating pattern
Answer:
C) The student and desk have to be in contact to apply the force.
Explanation:
I am pretty sure :)
Psychical(you see the changes visible) and Chemical properties(they react and combine, you may see fizzing or bubbles).
The correct answer should be B) Water vapor and carbon dioxide in the atmosphere trap heat.
The trapped heat cannot leave the atmosphere and as it is trapped, it increases the heat of the planet.
