Answer:

The answer to your question is:

                                                    Psi = 14.7

                                                     Atm = 1

                                                     kPa = 101.3          

Explanation:

Psi: means "Pounds of force per Square Inch of area " an is a unit of pressure.

Atm: means atmosphere and is a unit of pressure defined as 101325 Pa.

kPa: is defined as the force of 1 Newton applied over one square meter.

      ( 101325 Pa = 101.3 kPa)

Then

        Psi = 14.7

         Atm = 1

         kPa = 101.3

A solution of NaOH is titrated with H2SO4. It is found that 20.05 mL of 0.3564 M H2SO4 solution is equivalent to 43.42 mL of NaO
Darya [45]

Answer : The concentration of NaOH is, 0.336 M

Explanation:

To calculate the concentration of base, we use the equation given by neutralization reaction:

n_1M_1V_1=n_2M_2V_2

where,

n_1,M_1\text{ and }V_1 are the n-factor, molarity and volume of acid which is H_2SO_4

n_2,M_2\text{ and }V_2 are the n-factor, molarity and volume of base which is NaOH.

We are given:

n_1=2\\M_1=0.3564M\\V_1=20.05mL\\n_2=1\\M_2=?\\V_2=43.42mL

Putting values in above equation, we get:

2\times 0.3564M\times 20.05mL=1\times M_2\times 43.42mL

M_2=0.336M

Thus, the concentration of NaOH is, 0.336 M

Which ion is larger? Cu+ Cu2+ Why? Because Cu2+ has the filled 4s subshell. Because Cu2+ cannot be oxidized further. Because Cu2
jek_recluse [69]

The atomic number of Cu = 29

Valence electron configuration of Cu = 3d¹⁰4s¹

Cu+ is formed when 1 electron is lost from Cu. Therefore, the atomic number for Cu+ = 28

Similarly, loss of 2 electrons from Cu results in Cu2+ with an atomic number = 27

Cu+ is the larger ion. This is because as electrons are removed from the valence orbitals, the attraction between the outer electrons and the nucleus tends to increase which then results in a decrease in size.

Ans: Cu+ has one more electron
