How many total electrons can be contained in the 4d sublevel?
2
6
10
14

Answers

Answer 1

Answer: The s sublevel has just one orbital, so can contain 2 electrons max. The p sublevel has 3 orbitals, so can contain 6 electrons max. The d sublevel has 5 orbitals, so can contain 10 electrons max. And the 4 sublevel has 7 orbitals, so can contain 14 electrons max.
So, having this in mind, 10 electrons in total can be contained in the 4d sublevel.

Answer 2

Answer: The maximum number is 10

If there is no net force on an object, then the object will a) continue to accelerate
B) begin moving slow down
c) maintain it's rate of speed
d) have to be at rest

Answers

If there is no net force on an object, then the object will maintain it's rate of speed. Basically, net force is the change in an object's motion. If it is stationary and not moving, the object will stay stationary. If the object is moving at a rate of 2 miles per hour, it will constantly continue to move 2 mph because there is no net force.

The reaction converting glycerol to glycerol-3-phosphate can be represented as: glycerol + hpo42− ⟶ glycerol-3-phosphate + h2o. the gibbs energy for this reaction is δg∘ = 9.2 kj/mol. will this reaction be spontaneous if coupled with the hydrolysis of atp?

Answers

Answer:

Yes, this reaction will be spontaneous.

Explanation:

A reaction is spontaneous if ΔG < 0.

The coupling of glycerol to glycerol-3-phospate with ATP gives:

glycerol + HPO₄²⁻ ⟶ glycerol-3-phosphate + H₂O ΔG = +9,2 kJ/mol

ATP + H₂O ⟶ ADP + HPO₄²⁻ ΔG = -30,5 kJ/mol

glycerol + ATP ⟶ ADP + glycerol-3-phosphate

ΔG = +9,2 kJ/mol - 30,5 kJ/mol = -21,3 kJ/mol

As ΔG<0, this reaction will be spontaneous

I hope it helps!

Answer;

Yes; this reaction be spontaneous if coupled with the hydrolysis of ATP.

Explanation;

The reaction converting glycerol to glycerol-3-phosphate (energetically unfavorable) can be coupled with the conversion of ATP to ADP (energetically favorable):

Glycerol + HPO42 ⟶glycerol-3-phosphate+H2O

ATP + H2O⟶ ADP + HPO42− + H+

Which of the following has the greatest effect on colligative properties?A. Epsom salt (MgSO4)
B. Calcium chloride (CaCl2)
C. Potassium Iodide (KI)
D. Glucose (C6H12O6)

Answers

Answer:

Option B. Calcium chloride (CaCl₂)

Explanation:

The colligative properties depend on the concentration of particles (molecules or ions) of solute dissolved and not on the identity of the solute.

For your reference the colligative properties are: i) boiling point increase, ii) freezing point depression, iii) vapor pressure lowering, and iv) osmotic pressure.

When the solute is a ionic compound the ionization yields several ions, so for ionic solutes you must predict first the number or ions formed per unit of compound and then predict the effect on the colligative properties: the greater the number of ions per unit of compound the greater the effect on colligative properties.

So, just set the ionization equations for each compound:

MgSO₄ (aq) → Mg²⁺ (aq) + SO₄²⁻ (aq): 2 ions

CaCl₂ (aq) → Ca²⁺ (aq) + 2Cl⁻ (aq) : 3 ions

KI (aq) → K⁺ (aq) + I⁻ (aq): 2 ions

C₆H₁₂O₆ is a molecular compound, not a ionic one, so it remains s 1 molecule.

Then, since calcium chloride, CaCl₂, produces the greater number of ions it is the solute that productes the greatest effect on colligative properties.

Answer:

D. Calcium chloride (CaCl2)

Write the ionic equation for the reaction of aqueous propanoic acid with aqueouspotassium hydroxide.

Answers

The ionic equation for the reaction of aqueous propanoic acid (CH3CH2COOH) with aqueous potassium hydroxide (KOH) can be written as follows:

CH3CH2COOH + OH- → CH3CH2COO- + H2O

In this equation, propanoic acid (CH3CH2COOH) reacts with hydroxide ions (OH-) from potassium hydroxide (KOH) to form the propanoate ion (CH3CH2COO-) and water (H2O).

Which kind of wave increases in height due to strong winds?

Answers

The kind of wave that increases in height due to strong winds is a surface wave. Surface wave is a type of mechanical wave where it propagates along the interface of two different media. They have larger amplitudes and longer wavelengths. The height of these waves depends on the two different medias.

Answer: Ocean surface wind

Explanation: Ocean surface wind are generated in the ocean due to the abrasion or rubbing between the prevailing wind and the surface waves. They are formed at the top of the ocean surface.

When the wind is very strong, it generates surface waves of bigger wavelength and bigger height. But at the bottom, the waves moves at a slower rate. This waves are formed due to the wind.

This waves can rise upto hundreds of feets during tsunamis. Thus, this waves breaks as they reach the shoreline.
