All the given species have the same charge except peroxide.
<h3>Charges on ions</h3>
- The charge on monohydrogen phosphate is negative because of its formula,
![[HPO4]^{2-}](https://tex.z-dn.net/?f=%5BHPO4%5D%5E%7B2-%7D)
.
- The charge on permanganate is negative. The formula is
- The charge of oxide (
) is negative.
- The charge on peroxide is ( R−O−O−R) is neutral.
- The charge on oxalate,
, is negative.
Thus, only peroxide is unique.

Following are the pair of elements that result in an ionic compound
Option A and B
<u>Explanation:</u>
- Ionic compounds are defined as the compound that consists of ions held by two atoms of differently charged ions.
- These compounds have a positive charge of ions called cations and a negatively charged element is anions.
- In the above options, we shall say that the atoms such as Ca and K both result in cations as they release an electron to become a positive ion.
- Also, Cl and S both result in anions as they attract more electron to form negative ions.
- These positive and negative ion together results in an ionic compound.
Answer:
b) Linear molecule with two domains
Explanation:
The image represents a linear molecule with two domains.
The compound shown here is carbon dioxide in which a central carbon atom is surrounded by two oxygen atoms.
- This bond geometry is of the type AX₂
- In this linear molecule the bond angle is a perfect 180°
- The lone pairs are perfectly balanced out and will not cause distortion of the central carbon.
The bare rock will erode, once it erodes the rock will no longer be bare cause eroded sediment will cover it.
