Each incomplete reaction is a neutralization reaction. match each equation with the salt formed. 1. h2so4 + 2nh4oh → ? 2. 2naoh + h2co3 → ? 3. hno3 + koh → ? reaction : na2co3 reaction : kno3 reaction : (nh4)2so4

1. H₂SO₄ + 2NH₄OH ⟶ (NH₄)₂SO₄ + 2H₂O

2. 2NaOH + H₂CO₃ ⟶ Na₂CO₃ + 2H₂O

3. HNO₃ + KOH ⟶ KNO₃ + H₂O

Explanation:

Acid + base ⟶ salt + water

Take the H from the acid and the OH from the base to get water.

Then, join what’s left to get the salt. Write the symbol for the metal first.

For example, in equation 3, take the H from HNO₃ and the OH from KOH.

Combining the remaining parts (NO₃ and K) to get the salt, KNO₃.

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
