The average atomic mass of element X is 14.007 u.
The average atomic mass of X is the <em>weighted average</em> of the atomic masses of its isotopes.
We multiply the atomic mass of each isotope by a number representing its <em>relative importance</em> (i.e., its % abundance).
Thus,
0.996 36 × 14.003 u =13.952 03 u
0.003 64 × 15.000 u = <u>0.054 60 u</u>
__________TOTAL = 14.007 u
It is basic because of the fact that it has a strong base which is KOH and a weak acid HCN and the strong base causes it to remain more basic.
Answer:
It's The amount of matter within the system remains the same and The cycle has a well-defined starting and stopping point.
Explanation:
<h2>Answer:</h2>
The correct answer is option D which is substances will pass in and out of the cell in an uncontrolled manner.
<h3>Explanation:</h3>
- Cell membrane is outer organelle in the cell, it is responsible for the transport of materials into and out to the cell through osmosis and active transport.
- In the absence of the cell membrane, there will not be control of transport of a materials to the cell.
- Energy production is the task of mitochondria and food storage is the function of vacuoles.
- Photosynthesis takes place on the chloroplasts.
In here Oxygen is the central atom. It makes two bonds with
Cl and has two lone pairs. Since, the shape is bent and the hybridization is
sp3. Molecular geometry is a bit dissimilar from hybridization. Hybridization
is reliant on the number of bonds and lone pairs. Since O has two bonds with
Cl, its hybridization is sp3. It is like is this: 1 lone pair/bond = s. 2 lone
pairs/bond = sp 3 lone pairs/bonds = sp2, etc. molecular geometry, you count
the number of bonds and lone pairs. This has two bonds and 2 lone pairs so if
they were all bonds, the molecule would be tetrahedral.
