Question

Consider the following chemical reaction:

HF + NaOH - NaF + H20
Energy must be invested in order for the reaction to proceed.
What bonds must be broken in order for the reaction to proceed.
Select ALL that apply.
A. An ionic bond between sodium and hydroxide.
B. An ionic bond between sodium and fluorine.
C. A covalent bond between sodiume and fluorine.
D. An ionic bond between hydrogen and fluorine.
DE. A covalent bond between hydrogen and fluorine.
DE A covalent bond between hydrogen and oxygen

Answer 1

Answer: The correct options are A and E

Step-by-step explanation:

A chemical reaction is defined as the reaction in which two or more chemical substances react to form two or more different chemical substances.

A new substance (product) is formed in a chemical reaction when the bonds between the reactants are broken so that the new bonds between the products can be formed.

For a given chemical reaction:

`HF+NaOH\rightarrow NaF+H_2O`

Here,

HF is a covalent compound as sharing of electrons take place between hydrogen and fluorine atom

NaOH is an ionic compound as a complete transfer of electrons occurs from sodium to hydroxide.

Thus, to form the products, an ionic bond between sodium and hydroxide must be broken coupled with a covalent bond between hydrogen and fluorine.

Hence, the correct options are A and E
