<u>Answer:</u> The correct answer is Option b.

<u>Explanation:</u>

Water is the compound which is formed by the covalent bonding of hydrogen and oxygen atoms. The chemical formula for this compound is H_2O

Self-ionization of water is defined as the process in which 2 water molecules react together to produce hydroxide ion and hydronium ion.

The equation for the self ionization of water molecule follows:

2H_2O(l)\rightarrow H_3O^+(aq.)+OH^-(aq,)

By Stoichiometry of the reaction:

2 moles of water molecules react together to produce 1 mole of hydronium ion and 1 mole of hydroxide ion.

Hence, the correct answer is Option b.

A 1.250-g sample of benzoic acid, C7H6O2, was placed in a combustion bomb. The bomb was filled with an excess of oxygen at high
Degger [83]

Answer:

3224 kJ/mol

Explanation:

The combustion of benzoic acid occurs as follows:

C₇H₆O₂ + 13/2O₂ → 7CO₂ + 3H₂O + dE

The change in temperature in the reaction is the change due the energy released, that is:

3.256K * (10.134kJ / K) = 33.00kJ are released when 1.250g reacts

To find the heat released per mole we have to find the moles of benzoic acid:

<em>Moles benzoic acid -Molar mass: 122.12g/mol-:</em>

1.250g * (1mol / 122.12g) = 0.0102 moles

<em />

The dE combustion per mole of benzoic acid is:

33.00kJ / 0.0102moles =

<em>3224 kJ/mol </em>
