Answer: when water is evaporated from the earth whether that be from bodies of water or plants, when it goes up higher, the temperature drops, causing the water droplets to condense, which means form water. This creates clouds and when the clouds get too big and full, precipitation (rain) happens and the rain falls to the earth. This cycle is then repeated.

Explanation:
(a) potassium oxide with water
According to reaction,1 mole of potassium oxide reacts with 1 mole of water to give 1 mole of potassium hydroxide.
(b) diphosphorus trioxide with water
According to reaction,1 mole of diphosphorus trioxide reacts with 2 moles of water to give 2 moles of phosphorus acid.
(c) chromium(III) oxide with dilute hydrochloric acid,
According to reaction,1 mole of chromium(III) oxide reacts with 6 moles of hydrochloric acid to give 2 moles of chromium(III) chloride and 3 moles of water.
(d) selenium dioxide with aqueous potassium hydroxide
According to reaction,1 mole of selenium dioxide reacts with 2 moles of potassium hydroxide to give 1 mole of potassium selenite and 1 mole of water.
The claim that the strongest intermolecular interactions between propanol molecules arises from hydrogen bonding is True.
Intermolecular forces are weaker attraction forces that are utilized to define physical characteristics of molecules such as:
- boiling point
- temperature
- density
- melting points
Hydrogen bonding is an type of intermolecular forces.
It is a type of dipole-dipole interaction that only happens when a hydrogen atom is connected to the atomic element of oxygen, nitrogen, or fluorine.
From the question given, in the propanol (CH3CH2CH2OH) molecule, the hydrogen usually has a partially positive charge which attracts the partially negative charge of the oxygen.
Therefore, we can conclude that the claim is True.

Answer:
D. Conductor
Explanation:
Conductors are the substances which are good conductors of both heat and electricity. These substances have free electrons present around the nucleus which is the main reason for conduction. Metals like copper, gold, silver, iron and steel etc are the examples of conductor. Gold is best conductor but cannot be used due to high cost. After gold, copper is the best conductor so that's why it is used extensively in electric wires.
