Is the equation balanced? Why or why not?
Na3PO4 + 3 KOH --> 3 NaOH + K3PO4
O Yes because the law of conservation of energy is followed. There are equal amounts of energy in the reactants and
products.
No because the law of conservation of energy is not followed. There are different amounts of energy in the reactants
and products.
No because the law of conservation of matter is not followed. The mass of the reactants is greater than the mass of the
products.
o Yes because the law of conservation of matter is followed. There are equal numbers of atoms of all elements in the
reactants and products.

Yes because the law of conservation of matter is followed. There are equal numbers of atoms of all elements in the

reactants and products.

Explanation:

A balanced equation conform to the law of conservation of matter. While unbalanced equation suggests that matter has been created or destroyed.

Na3PO4 + 3KOH —> 3NaOH + K3PO4

A careful observation of the above equation proved that the equation is balanced is balanced because there are equal numbers of atoms of all elements in the

reactants and products.

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.
