Answer:
Volume of solution = 80.5 mL
Explanation:
Given data:
Molarity of solution = 4.50 mol/L
Mass of ethanol = 16.7 g
Volume of solution = ?
Solution:
Volume will be calculated from molarity formula.
Molarity = number of moles / volume in L
Number of moles:
Number of moles = mass/molar mass
Number of moles = 16.7 g/ 46.07 g/mol
Number of moles = 0.3625 mol
Volume of solution:
Molarity = number of moles / volume in L
4.50 mol/L = 0.3625 mol / volume in L
Volume in L = 0.3625 mol /4.50 mol/L
Volume in L = 0.0805 L
Volume in mL:
0.0805 L ×1000 mL/1 L
80.5 mL
If a dynamic equilibrium is disturbed by changing the conditions, the position of equilibrium shifts to counteract the change to reestablish equilibrium. If a chemical reaction is at equilibrium and experiences a change in pressure, temperature, or concentration of products or reactants, the equilibrium shifts in the opposite direction to offset the change. This page covers changes to the position of equilibrium due to such changes and discusses briefly why catalysts have no effect on the equilibrium position.
For example, if the system is changed in a way that increases the concentration of one of the reacting species, it must favor the reaction in which that species is consumed. In other words, if there is an increase in products, the reaction quotient, Qc, is increased, making it greater than the equilibrium constant, Kc.

Answer:
Advantage: Hydropower is a fueled by water, so it's a clean fuel source.
Advantage: It is a domestic source of energy in the US.
Disadvantage: Fish populations can be impacted if fish cannot migrate upstream past impoundment dams to spawning grounds or if they cannot migrate downstream to the ocean.
Disadvantage: Hydropower plants can be impacted by drought. When water is not available, the hydropower plants can't produce electricity.
