Margarita [4]

Answer:

This question is incomplete; the complete part is:

A) All cell have a cell wall.

B) All cell arise from pre-existing cells.

C) All cell are capable of photosynthesis.

D) All cell can develop into any other type of cell.

The answer is B

Explanation:

The commonly known universal theory proposed in 1838 took the contribution from three remarkable scientists namely: botanist Matthias Schleiden, anatomist Theodor Schwann and biologist Rudolph Virchow. According to the question, Mathias discovered that all plants are made of cells, Schwann determined that all animals are made of cells while Virchow determined that all living things are composed of cells.

However, in addition to Virchow's discovery, he also discovered and proposed that "All cell arise from pre-existing cells", which till date forms part of the three components of the cell theory. The three parts are:

- Cell is the fundamental and basic unit of all living things.

- All living things are made up of one or more cells

- All cells arise from pre-existing cells

Use molecular orbital theory to determine whether He2 2+ or He2 + is more stable. Use molecular orbital theory to determine whet
julia-pushkina [17]

Answer:

The He₂ 2+ ion is more stable since it has a higher bond order (bond order = 1) than the He₂ + ion (bond order = 1/2).

Explanation:

Molecular orbital of He₂⁺

1\sigma_{1s}^21\sigma(star)_{1s}^1

There are two electrons in bonding and 1 electron in antibonding orbital

Bond order = \frac{(2-1)}{2}    

= \frac{1}{2}

Molecular orbital of He₂⁺²

1\sigma_{1s}^21\sigma(star)_{1s}^0

There are two electrons in bonding and 0 electron in antibonding orbital

Bond order = \frac{(2-0)}{2}

= 1

So bond order of He₂⁺² is 1 which is more stable than He₂⁺ whose bond order is   \frac{1}{2}   .
