Select the correct electron configuration for Vanadium. (Atomic Number 23) 1s22s62p33s 23p44s23d5 1s22s22p63s 23p84s23d1 1s22s22
True [87]
The  correct  electronic configuration of  vanadium  23  is

 1s^22s^22p^63s^23p^64s^23d^3

This  electronic configuration  is correct because it obeys  the Aufbau principle which  state  that  electrons  fill the atomic  orbital  of  the lowest  energy  before  occupying the higher level. S  orbital  can occupy a total of  2  electrons, p orbital  can  occupy a total of  6  electrons  while d orbital can occupy a total of  10 electrons. in the  electronic configuration above  an  s orbital  is filled  before p orbital  while  the  p  orbital is  filled before  the d orbital .

Glycogen ________. Glycogen ________. forms the regulatory molecules known as enzymes serves as a structural component of human
jasenka [17]

Answer:

Glycogen in an important storage polysaccharide found in animal tissues.

Explanation:

Full question:

Glycogen ________

A) forms the regulatory molecules known as enzymes

B) serves as a structural component of human cells

C) helps to protect vital organs from damage

D) is an important storage polysaccharide found in animal tissues

E) contains the genetic information found in cells

Glycogen is a complex polysaccharide of glucose founded in humans, animals, fungi and even bacteria. In humans, the glycogen is made and stored in liver cells. In the center on glycogen molecule, there is a single protein called Glycogenin. It is a center of a big flower made of glucose molecules (please refer to the scheme attached - Glycogenin is red and the blue lines are glucose chains). Glycogen is also stored in skeletal muscle, red and white blood cells, in glial brain cells and kidneys but in a smaller amounts. It can be found in the placenta in pregnant women where it serves as a nutrient storage for embryo. In an adult, the liver weighs 1,5 kg and glycogen weighs about 120g in such a liver. After a meal, the level of sugar is rising and the insulin is being secreted. Insulin is a tool by which sugar is being delivered to the cells, like a food delivery. During this period, glycogen is being synthesized in the liver out of glucose residues. When the meal is digested, the sugar level is back to normal. When more energy is needed, glycogen from the liver is broken down by glycogen phosphorylase and the new sugar is released into the bloodstream.

Which statement about the balanced equations for nuclear and chemical changes is correct? (1 point)
iris [78.8K]

The true statement about the balanced equations for nuclear and chemical changes is; both are balanced according to the total mass before and after the change.

A basic law in science is called the law of conservation of mass. Its general statement is that mass can neither be created nor destroyed.

Both in chemical and nuclear changes, mass is involved and in both cases, the law of conservation of mass strictly applies.

This means that for both chemical and nuclear changes; total mass before reaction must be equal to total mass after reaction.

Hence, both reactions are balanced according to the total mass before and after the change.
