Answer: Option (D) is the correct answer.
Explanation:
Atomic number of lithium is 3 and electrons in its shell are distributed as 2, 1. Atomic number of chlorine is 17 and electrons in its shell are distributed as 2, 8, 7.
Thus, we can see that lithium has 1 extra electron and chlorine has deficiency of 1 electron. Therefore, in order to gain stability lithium will transfer its 1 extra electron to chlorine atom.
Thus, we can conclude that electrons are transferred from the lithium atom to the chlorine atom.
Theoretical yield 550 kg - 100%
Actual yield 480 kg - x%
x= 480*100/550 ≈ 87.3 %
Percentage yield ≈ 87.3 %.
The bond angle marked as ‘a’ in the molecule above is about: D. 120 degrees. That means the angle between the atoms forms a trigonal planar shape.
<h3>What is the bond angle?</h3>
The bond angle is an angle between two bonds that measures in degrees and is calculated by using the spectroscopic method. The bond angle depends on the bonds and the number of lone pairs an atom has.
The molecule above contains 3 electron charge clouds around them: a single bond to carbon, a single bond to oxygen, and a double bond to the other oxygen. Hence, the O-C=O bond angle from the molecule above is 120 degrees.

A single water molecule can form 4 Hydrogen Bonds.
A hydrogen atom that is linked to a highly electronegative atom and another highly electronegative atom that is close by interact with one another to form hydrogen bonds, which are an unique kind of attractive intermolecular interactions. This process is known as hydrogen bonding. Hydrogen, for instance, is covalently linked to the more electronegative oxygen atom in water molecules (H2O). Therefore, the dipole-dipole interactions between the hydrogen atom of one water molecule and the oxygen atom of another H2O molecule are what cause hydrogen bonding to form in water molecules.

Answer: 3 bromite ions and 
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
Here scandium is having an oxidation state of +3 called as 
cation and bromite is an anion with oxidation state of -1 called as 
. Thus 1 Scandium ion combines with three bromite ions and their oxidation states are exchanged and written in simplest whole number ratios to give neutral
