Answer:
Potassium = Great conductor of heat and electricity
Neon = Non reactive
Boron = has properties of both metals and non metals
Barium = Malleable and highly reactive
Explanation:
Potassium = Great conductor of heat and electricity
Potassium is soft metal and has low melting point. It is white silvery luster with great heat conducting properties.
Neon = Non reactive
Neon is present in group eighteen. It is noble gas. Its outer electronic shell is completely filled that's why it is non reactive.
Boron = has properties of both metals and non metals
Boron is metalloid and behave like both metals and non metals.
Barium = Malleable and highly reactive
Barium is belong to group 2A. It is alkaline earth metal. It is highly reactive towards other elements such as oxygen, fluorine, chlorine , etc.
Answer:
The first box would be the pH will decrease, and the acidity will increase, and for the second box, the pH will increase, and the acidity will go down.
Explanation:
As the hydronium concentration increases, the pH decreases, and therefore if the hydromnium concentration decreases, the pH will increase. pH is sort of backwards, as the level increases, the acidity will go down, and as it decreases, the acidity will go up.
