Answer: 2
Explanation: Potassium, K, has only 1 valence electron, 4s^1. Oxygen, O, needs 2 more electrons to complete its valence shell to make 8 electrons. That means 2 K atoms will combine with 1 O atom, to produce K2O, potassium oxide. Both K electrons are stolen by the single O atom, so 2 electrons are transferred.
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.
Answer:
Explanation:
From the question we are told that:
Volume of hydrogen 
Temperature 
Pressure of water 
Let
STP(Standard Temperature and pressure)
Generally the equation for ideal gas is mathematically given by
Therefore
(at STP(Standard Temperature and pressure))
