Answer:
3.01 x 10 to the power of 6
Explanation:
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 3,010,000
New Number: 3.010000
Step 2
Now, to find b, count how many places to the right of the decimal.
Answer:
D) CN⁻
Explanation:
Hund's Rule of Maximum Multiplicity state that electrons go into degenerate orbitals of sub-levels (p,d, and f ) singly before pairing commences. Hund's rule is useful in determining the number of unpaired electrons in an atom. As such, it explains some magnetic properties of elements.
An element whose atoms or molecules contain unpaired electrons is paramagnetic. i.e., weakly attracted to substances in a magnetic field.
On the other hand, the element whose atoms or molecules are filled up with paired electrons is known as diamagnetic, i.e., not attracted by magnetic substances.
According to the molecular orbital theory, the diamagnetic molecule is CN⁻ because of the absence of unpaired electrons.
Answer:
6
Explanation:
The coordination number of a particular crystal structure arrangement is defined as the number of nearest neighbor atoms or ions surrounding an atom or ion.
We must note that in salts of the type MX, the coordination number of each ion must be equal. The structure of LiCl is built by placing each unit cell next to another such that ions residing in the corner, edge or face sites are shared between adjacent unit cells. The LiCl is in FCC arrangement.
Hence in LiCl, each Li+ ion is surrounded by 6 chloride ions.
How do cells get ATP through Cellular Respiration.
Cellular respiration takes place in the mitochondria. The Mitochondria use oxygen (O2) to convert broken-down glucose (at type of sugar) into carbon dioxide (CO2) and water (H2O).
The reactants of CR are oxygen and glucose.
The products of CR are ATP, carbon dioxide, and water.
