Answer:

ml= 0

Explanation:

The magnetic quantum number usually gives information regarding the directionality of an atomic orbital. The values of the magnetic quantum number ranges between integer values that lie between +l to -l.

However, the n=1 level contains only the 1s orbital which is spherically symmetrical. The s orbital having l=0 also has magnetic quantum number (ml) =0, hence the answer.

What would be the volume in liters of 640g of oil if the density of the oil is 0.8g/mL

Alexus [3.1K]

Hey there!

Mass = 640 g

Density = 0.8 g/mL

Volume = ?

Therefore:

D = m / V

0.8 = 640 / V

V = 640 / 0.8

V = 800 mL

hope that helps!

2-phosphoglycerate(2PG) is converted to phosphoenolpyruvate (PEP) by the enzyme enolase. The standard free energy change(deltaGo

pogonyaev

Answer:

The correct option is: (D) -2.4 kJ/mol

Explanation:

Chemical reaction involved: 2PG ↔ PEP

Given: The standard Gibb's free energy change: ΔG° = +1.7 kJ/mol

Temperature: T = 37° C = 37 + 273.15 = 310.15 K (∵ 0°C = 273.15K)

Gas constant: R = 8.314 J/(K·mol) = 8.314 × 10⁻³ kJ/(K·mol) (∵ 1 kJ = 1000 J)

Reactant concentration: 2PG = 0.5 mM

Product concentration: PEP = 0.1 mM

Reaction quotient: $Q_{r} =\frac{\left [ PEP \right ]}{\left [ 2PG \right ]} = \frac{0.1 mM}{0.5 mM} = 0.2$

To find out the Gibb's free energy change at 37° C (310.15 K), we use the equation:

$\Delta G = \Delta G^{\circ } + 2.303 R T log Q_{r}$

$\Delta G = 1.7 kJ/mol + [2.303 \times (8.314 \times 10^{-3} kJ/(K.mol))\times (310.15 K)] log (0.2)$

$\Delta G = 1.7 + [5.938] \times (-0.699) = 1.7 - 4.15 = (-2.45 kJ/mol)$

Therefore, the Gibb's free energy change at 37° C (310.15 K): ΔG = (-2.45 kJ/mol)

What is the ph of a solution that has a [h ] = 0. 0039 m?

Sedbober [7]

The pH of a solution that has a H⁺ ion concentration is 0.0039M is 2.4.

pH of any solution gives idea about the acidity or basicity of solution and it will be calculated as:

pH = -log[H⁺]

Given that, concentration of H⁺ ion = 0.0039 M

On putting tis value in pH equation, we get

pH = -log(0.0039)

pH = -(-2.4) = 2.4

Hence required value of pH is 2.4.
