Answer:
Rubidium belong to Alkaline group 1, and
Strontium belong to Alkaline group 2.
Explanation:
We know that elements are organized on the periodic table based on their properties. The statement correctly predicting and explaining the chemical reactivity of two metals is given below -Rubidium (Rb) is more reactive than strontium (Sr) because strontium atoms must lose more electrons.

Answer:
D) Condensation of a gas into a solid.
Explanation:
An endothermic process is a process that absorbs heat from the surroundings.
A) Boiling a liquid.
This gives off heat to the surroundings. An exothermic process.
B) Freezing a solid.
In this process, the water releases heat to the surroundings, so it is an exothermic process
C) Condensation of a gas into a liquid.
As water vapor condenses into liquid, it loses energy in the form of heat. Therefore, this process is exothermic.
D) Condensation of a gas into a solid.
This process absorbs heat from the surrounding, hence it is an endothermic proccess.
