Molarity = moles of solute/volume of solution in liters.
There are 2.66 moles of KOH, the solute, and the volume of the solution is 0.750 L.
The molarity of this solution would thus be (2.66 moles KOH)/(0.750 L) = 3.55 M KOH.
Answer:
The forward and the reverse processes are both spontaneous. (Ans. B)
Explanation:
When a system is at equilibrium state, then the rate of backwards, and forward, both reactions becomes equal. Which means the forward and the reverse processes are both spontaneous.
With the help of entropy change of the reaction, and Gibbs free energy we can determine the spontaneity of a reaction. If entropy changes is positive, and Gibbs free energy changes a negative, then the reaction will say to be spontaneous.
Answer:
The Axis Powers took these aggressive actions prior to the outbreak of World War II which include the invasion of Ethiopia, Manchuria, and the Rhineland.
Explanation:
Axis Powers: It was the coalition of Germany, Italy and Japan against the <em>Allied Powers</em> (the United States, the Soviet Union, Great Britain, and China) in World War II.
- In 1930, the Japanese took control of railway track in Manchuria (a region in China) and in 1931, the Japan attacked the Chinese army claiming that the Chinese soldiers sabotaged the railway.
- On 3 October 1935, Italy invaded the Ethiopia (former name: Abyssinia) in the leadership of <em>Mussolini </em>to expand its territories.
- Germany in the leadership of Adolf Hitler occupied the Rhineland in 1937 by making excuse that the area is hostile and dangerous for them.
