Filling of electrons in an orbitals takes place by using following rules:

Aufbau rule: Filling of electrons takes place in an energy levels in the increasing order of energy that is the one having lowest energy will fill first.

Hunds rule: No second electron will be filled in an orbital until each orbital occupies a single electron.

Pauli exclusion principle: No two electrons can have same spin in an orbital.

So here also also the rules must be applied in filling electrons , by Aufbau rule, energy level that is having lower energy in this case after 5s it will be 4d¹, will fill first. So the answer is 4d¹.

A scientist discovers a new type of polymer. What must be true about this polymer?
DochEvi [55]

The correct answer is D

a polymer is a substance made up of large molecules with repeating sub units called monomers.

A is incorrect because its a ring structure which means it cannot form the long chain that is exhibited by polymers.

B is incorrect because the double bonds will cause saturation, hence no monomer can bond to another monomer to form the large molecule.

C is incorrect because the large molecule  has repeating sub-units hence only specific types of molecules can be present, and it is usually carbon and hydrogen.

Which type of lipid is found in the body and is converted into vitamins, hormones, and bile salts?
Illusion [34]

Answer:

C.sterols

Explanation:

Sterols or steroid alcohols are type of lipids. In plants they are present as phytosterols and in animals as zoosterols. They maintain the fluidity of cell membrane, act as signalling molecules and also form the skin oils in animals.

Cholesterol is an important zoosterol. It is a fatty waxy substance. It is present in cell membrane. It is also a precursor for vitamin D. It is precursor for steroid hormones like cortisol and aldosterone. When it is non esterified, it gets converted to bile.

BRAINLIEST AWARD!! Why is potassium nitrate a solute in a .3M potassium nitrate solution? Please explain:D
Bond [772]

Answer:

In a .3M KNO3 solution, the KNO3 is dissolved in water. Water is the solvent and KNO3 is the solute, because the solute is what is dissolved. Also, all potassium compounds and nitrate compounds are soluble, so you know that KNO3 dissociates into K+ and NO3- in water.

When a reaction occurs, what happens to the energy?
puteri [66]
Chemical reactions often involve changes in energy due to the breaking and formation of bonds. Reactions in which energy is released are exothermic reactions, while those that take in heat energy are endothermic.
