2) Cold War tensions increased.
The Bay of Pigs invasion was carried out by Cuban exiles that had been trained by the United States' Central Intelligence Agency (CIA). The Cuban counter revolutionaries failed and Kennedy was embarrassed. Within just days, the force of exiles was soundly defeated by the Cuban Revolutionary Armed Forces, commanded by Fidel Castro. In the aftermath of the Bay of Pigs affair, Cuba requested that the USSR, as its communist sponsor, place missiles in Cuba to deter further US-sponsored action against the Castro regime.

Answer: The v/v in percent of diethyl ether in a solution is 2%.
Explanation:
To calculate the percentage volume by volume of a solute in a solution, we use the formula:
We are given:
Volume of solute = 50 mL
Volume of solution = 2.5 L = 2500 mL (Conversion factor: 1 L = 1000 mL)
Putting values in above equation, we get:
Hence, the v/v in percent of diethyl ether in a solution is 2%.
Answer : Rust forms when oxygen reacts with chemicals in rocks.
Explanation :
Rusting : It is a chemical process in which an iron react with oxygen to give an iron(III)oxide as a product. The product iron(III)oxide formed from the chemical reaction is known as rust.
The chemical reaction will be,
Hence, rust forms when oxygen reacts with chemicals in rocks.
