Answer:

The middle Hydrogen atom is bonded to two instead of one atom

Oxygen is bonded to one instead of two atoms

Oxygen has three instead of two lone pairs of electron.

Explanation:

If we look at the structure, we will notice that it does not satisfy the basic principles of valency.

Hydrogen has a valency of 1. However, the middle hydrogen atom is bonded to two atoms instead of only one atom - the other atom of hydrogen and an atom of oxygen.

Secondly, oxygen has three lone pairs instead of two lone pairs, hence it is bonded to only one instead of two atoms. This does not correspond to the known valency of oxygen.

Answer: Hydrogen cannot have more than two electrons.

Hydrogen bonds to only one other atom at a time.

There are too many electrons in the final structure.

Explanation: did it on edge

What element is found in liver and is needed to prevent anemia or tired blood.
DochEvi [55]


The element found in the liver that helps prevent anemia is iron.

Iron is an essential element for blood production. Close to 70% of the body's iron is found in the red blood cells. In the red blood cells it is a vital ingredient of hemoglobin, the red pigment that gives blood its red color. In the muscle cells, iron is found as myoglobin.

Iron is stored mostly in the liver as ferritin or hemosiderin.

When iron stores are finished or exhausted, the condition is called iron depletion. When the shortage of iron is severe, it results in a condition known as iron deficiency anemia whereby the red blood cells do not have enough hemoglobin.

What type of reaction is shown below? Check all that apply. Ca + 2H2O → Ca(OH)2 + H2 synthesis decomposition combustion single r
Ksju [112]

The balanced reaction is

Ca + 2H2O → Ca(OH)2 + H2

Here this reaction can be compared with

A + BC  ---> AB + C

So here one reactant (A) is accepting a group which is being given by another compound (BC) however the A is not giving any group / element or ion

So this single displacement

Similarly in the given reaction

the anion OH- is only being replaced

The element Ca accepts OH- and H2O loses the same group to form new element H2

So the correct answer is

Single replacement also known as single displacement

An element has an atomic mass of 69.66 amu. It has two
marin [14]

Answer: 63.26%

Explanation:

If we let the abundance of the first isotope be x, then:

69.66=(68.9255)(x)+(70.9247)(1-x)\\69.66=68.9255x+70.9247-70.9247x\\-1.2647=-1.9992x\\x=\frac{-1.2647}{-1.9992} \approx 0.6326

Which is equal to <u>63.26%</u>
