1.1 Moles / 0.5 Liters = 0.22 Molarity
First, they may produce direct and relatively short-lived effects, such as stimulation of the isolated uterus or relaxation of the isolated tracheal chain preparation.
Secondly, in doses too low to produce a direct effect, they may produce a long-term potentiation of the effects of other stimulants.
Bromine has 35 protons, and in this case 46 neutrons, so 35 + 46 = 81
Therefore, the symbol is (subscript 35)(superscript 81) Br.
Answer:
Kb = 
Explanation:
For a weak organic base, the formula to find 
is given by:
where c is the concentration of base.
Here c= 
Substituting the above values in the formula,we get:
Hence:
Kb =
Answer:
Freezing
Melting
Condensation
Evaporation
Sublimation
Deposition
Explanation:
From the diagram,
(1) Liquid⇒Solid (Freezing)
Freezing: This is the process by through which a substance change from liquid to solid.
(2) Solid⇒Liquid (Melting)
Melting: This is a process through which a substance change from solid to liquid
(3) Liquid⇒gas (Evaporation)
Evaporation: This is a process through which a substance change from liquid to gas.
(4) gas⇒Liquid (Condensation)
Condensation: This is a process through which a substance change from gas to liquid
(5) Solid⇒gas (Sublimation)
Sublimation: this is a process through which a subtance change from solid to gas
(6) gas⇒solid (Deposition)
Deposition: This is a process through which gas transform into solid.
