Answer: The values for Ka and Kb for the species in solution must be known before a prediction can be made
Explanation:
1. If Ka is greater than Kb, the salt solution is acidic
2. If Ka is lesser than Kb, the salt solution is basic
3. If Ka is equal to Kb, the salt solution is acidic
Im pretty sure the answer is the atmosphere provides warmth.

Answer:
Mass = 3626 g
Number of moles = 37 mol
Explanation:
Given data:
Volume of solution = 2.00 L
Molarity of solution = 18.5 M
Number of moles of solute = ?
Mass of solute = ?
Solution:
Molarity = number of moles / volume in L
By putting values,
18.5 M = number of moles / 2.00 L
Number of moles = 18.5 M × 2 L
Number of moles = 37 mol
Mass of solute:
Mass = number of mole × molar mass
Mass = 37 mol × 98 g/mol
Mass = 3626 g
