Answer: f. 2:2:2:1
Explanation: The reaction is a single displacement where Cs displaces H to pair up with OH.
The balance chemical equation is:
2 Cs + 2 H2O => 2 CsOH + H2
The number of atoms on both sides are equal.
Cs= 2
H= 4
O= 2

Answer:
1s2 2s2 2p6 3s2 3p6
Explanation:
Chlorine is a groups 17 element. The halogens for ions by accepting one electron to form univalent negative ions.
Since chlorine normally contains seventeen electrons, the chloride ion consists of eighteen electrons.
Hence the electronic configuration of chlorine ion is; 1s2 2s2 2p6 3s2 3p6.
Composite volcanoes
Explanation:
Volanoes are conduits that brings molten magma called lava to the surface of the earth. There are different kinds of volcanoes that forms as a result of the nature of the magma brought to the surface.
Some of these volcanoes are:
- Composite volcanoes
- Cinder cones
- Super volcanoes
- Shield volcanoes.
Composite volcanoes forms not only from lava flows but also from cinders of rocks that cools and solidifies very fast.
They are usually very large. Example is Mount St. Helens and Mount Pinatubo

Fluoride is an anion of Fluorine
What this means is that the two have the same number of protons (9), but Fluoride has 10 electrons compared to Fluorine's 9.
So the answers are:
Protons - 9
Neutrons - 9
Electrons - 10
Atomic Number - 9
Atomic Mass - 19 g/mol
