<u>Answer:</u> The correct options are A and E

<u>Explanation:</u>

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

The number of moles that are contained in the given mass of propane (C_3H_8 is 1.7143 moles.

<u>Given the following data:</u>

  • Mass of propane = 75.6 grams.

<u>Scientific data:</u>

  • The molar mass of propane = 44.1 g/mol.

To calculate the number of moles that are contained in the given mass of propane (C_3H_8):

<h3>How to calculate the moles of a compound.</h3>

In this exercise, you're required to determine the number of moles of propane that are contained in the given sample:

Mathematically, the number of moles contained in a chemical compound is given by this formula:

Number\;of\;moles = \frac{mass}{molar\;mass}

Substituting the given parameters into the formula, we have;

Number\;of\;moles = \frac{75.6}{44.1}

Number of moles = 1.7143 moles.
