Answer:
The correct option is: bent 109°
Explanation:
Covalent molecules are the molecules in which the atoms are linked by covalent bonds. The electrons involved in the formation of a covalent bond are known as shared pair or <u>bond pair of electrons</u>.
The three-dimensional arrangement of the atoms of a molecule in space is known its molecular structure or geometry.
<u>Given molecule</u>: XY₂, having two lone pairs around the central atom X.
Since the molecule XY₂ has <u>two lone pairs</u> and <u>two bond pairs</u> of electrons. Therefore according to the VSEPR theory, the given molecule has a <u>bent molecular geometry with 109° bond angle.</u>

hope this helps! :)
Answer:
The correct answer about geologic time scale is that, it presents the correct sequence of events in the history of the earth.
Geologic Time scale is being recorded in the history of geologics. It is being broken into smaller and larger subdivisions and this helps us to know how events fit together.
In order to study the major events which are found in geologic history we should study the rock strata which is found around the world.
Explanation:
Water with high levels of calcium ions is referred to as hard water. While hard water has health benefits, this type of water has economic implications in the industry and households too. In the industry, hard water can cause a breakdown of equipment such as boilers, over time. In the household, too much soap is used when washing with hard water than soft water. Therefore hard water requires to be softened before industrial use. Economically, this increases the cost of production.
It’s gonna be which ever element(s) that has the same number of valence electrons!!
