Answer : 4.8 florins can you exchange for your 4 guilders.
Solution : Given,
The current exchange rate for every 2.4 florins is 2.0 guilders
As per question,
The exchange rate is 2.0 guilders for every 2.4 florins
The exchange rate is 1 guilders for every 
florins
The exchange rate is 4 guilders for every 
florins
Therefore, the 4.8 florins can you exchange for your 4 guilders.
Answer:
0.1 M
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 100 mL
Initial concentration (C1) = 0.5 M
Final volume (V2) = 500 mL
Final concentration (C2) =?
Using the dilution formula C1V1 = C2V2, the new concentration of the solution can be obtained as follow:
C1V1 = C2V2
0.5 × 100 = C2 × 500
50 = C2 × 500
Divide both side by 500
C2 = 50/500
C2 = 0.1 M
Therefore, the new concentration of the solution is 0.1 M
Conduction - touching hot pot
Convection - oven cycling warm air
Conduction - touching a warm coffee mug
Heat from a fire - radiation
Heat from the sun to solar panel - radiation
Warm water rising - convection
Answer:
The pH of the solution is 8, 40-
Explanation:
The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and greater than 7 to 14 basic. It is calculated as
pH = -log (H30+)
pH= -log (4x10-9M)
<em>pH=8,40</em>
