The correct option is COVALENT BONDS.
A Lewis acid is defined as a substance which accept a pair of electron while a Lewis base refers to a substance that donate an unshared pair of electrons to another chemical specie with which it shared the donated pair of electrons.
Lewis acid and Lewis base react together to form salt and water. This type of reaction is called neutralization reaction. The neutralization reaction of Lewis acid and Lewis base involves electron pairs transfer, thus, there is an increase in the number of covalent bonds during this reaction.
During a combustion reaction the carbon in a hydrocarbon compound is paired with Oxygen (O2) in the air to form Carbon-Dioxide (CO2), whilst the Hydrogen too pairs with Oxygen to form water vapour (H2O). Heat is also produced during this reaction.
Answer:
Should be a 15 imo
Explanation:
N is one, 4H = 4, S 2 because of the 2 and O 8 because of the 4 and the 2 before the S.
Resultant aqueous solution of a hydrogen oxalate salt is basic in nature.
<h3>What is pH?</h3>
pH scale is used to determine the acidity, basicity or neutral nature of any solution.
- Values from 0 to 6.9 shows the acidity.
- 7 shows the neutrality.
- And 7.1 to 14 shows the basicity.
Chemical equation for the given salt in an aqueous solution will be shown as:
NaHC₂O₄ + H₂O → NaOH + H₂C₂O₄
From the equation it is clear that reaction produces-
- NaOH which is a strong base and
- H₂C₂O₄ oxalic acid which is a weak acid.
So that resultant solution is basic in nature.
Hence the aqueous solution of salt is basic.
