<u>Answer:</u> The final volume of the reaction is 4.69 L

<u>Explanation:</u>

The relationship of number of moles and volume at constant temperature and pressure was given by Avogadro's law. This law states that volume is directly proportional to number of moles at constant temperature and pressure.

The equation used to calculate number of moles is given by:

\frac{V_1}{n_1}=\frac{V_2}{n_2}

where,

V_1\text{ and }n_1 are the initial volume and number of moles

V_2\text{ and }n_2 are the final volume and number of moles

We are given:

V_1=2.05L\\n_1=0.280mol\\V_2=?L\\n_2=0.641mol

Putting values in above equation, we get:

\frac{2.05}{0.280}=\frac{V_2}{0.641}\\\\V_2=\frac{2.05\times 0.641}{0.280}=4.69L

Hence, the final volume of the reaction is 4.69 L

<span><span>NaOH + HCl --> NaCl + H2Oso here 1 mole of NaOH reacts with 1 mole of HCl. Hence it is required to convert the amount of HCl and NaOH in to moles.Number of HCl moles Concentration of the solution = 2.00M = 2 mol/ literVolume of the solution           = 22.4 mlNumber of HCl moles              = (2mol/1000 ml)*22.4 ml                                            =  0.0448 mol</span></span>

Why chlorine is higher in electro negativity and ionization energy
Nana76 [90]

Explanation:   • Electronegativity is the tendency of an atom to attract the electrons in a bond towards it. • Ionization energy is the energy that should be given to a neutral atom to remove an electron from it. The difference in the electronegativity between the two elements is quite small, but the main reason for it is because chlorine is one period below oxygen. Chlorine’s valence electrons are thus less tightly bound than those of oxygen, so they would have lower first ionization energy. Does sodium or potassium have larger ionization energy?
