Answer:
Ice and water on the ground affect incoming solar radiation by reflecting 4 percent of solar radiation that reaches the surface. ... When the sun angle is high and water is liquid notice, there is less reflection that takes place.
Two steps by inspection 1 qt = 0.25 gallons, 13.6 g/mL = 13.6 kg/L
0.25 gallon x 3.785411784 L/gallon x 13.6 kg/L x 1 lb/0.45359237 kg = 28.374 lb.
Hope this Helps!
Answer:
molarity of the KI solution = 0.04 mol/L
Explanation:
Molarity (M) is the concentration of a solution expressed as the number of moles of solute per liter of solution.
The law that we can applied to calculate the M is:
M = n / V
n - number of moles
V- volume of the solution (liters)
Then insert in the equation the values from the question;
M = 0.082 mol / 2.03 L = 0.04 mol/L
The answer is (1). The electrons transfer form one reactant to another means that there is the change of valence. For other choices, the valence of reactant does not change.
