Answer:

b. location c. luster d. taste

Explanation:

The following physical and chemical properties for identifying the mineral are Color, Hardness, Luster, Taste, Odor, Etc. The properties help in identifying the place of origin the mineral has come from.

In turn, location can be also used to identify a particular mineral or chemical origin. A mineral located in groundwater reserves has deposits of calcium and hence formed through the limestone rocks of the CaCo3 element.

Luster the reflectance properties of the rocks as some minerals don't have lust is called as "earthy," or "dull." And the color is an important property of the mineral and hence is a major tool in identifying the chemical and physical properties.

Other properties being Magnetism, Opaqueness and Specific Gravity.

The ways to identify a mineral are LUSTER, density, hardness, and cleavage.

Answer:

There are $\mathbf{8.90172 \times 10^{-14}}$ moles of bactoX present in a 3.0 μL sample volume that contains 7.512×106 bacterial cells

Explanation:

Given that:

The number of molecules present in one bacterial cell is $7.140 \times 10^3$ molecules

and the sample contains $7.512 \times 10^6$ molecules.

Number of moles = number of molecules /Avogadro's number

where;

Avogadro's number = 6.023 × 10²³

Number of moles = $\dfrac{7.140 \times 10^3}{6.023 \times 10^{23}}$

Number of moles = $1.185 \times 10^{-20}$ moles

So; $1.185 \times 10^{-20}$ moles is present in one bacteria cell

Similarly; the sample contains $7.512 \times 10^6$ molecules.

Therefore; the number of moles present in the bactoX is = $1.185 \times 10^{-20} \times 7.512 \times 10^6$

= $\mathbf{8.90172 \times 10^{-14}}$ moles

Answer:

4. Principal and Azimuthal (subsidiary) quantum number

5.Principal, Azimuthal (subsidiary), and magnetic quantum number

6. 10 electrons

7. 32 electrons

8. 36 electrons

Explanation:

4. Principal and Azimuthal (subsidiary) quantum number because in 4d, 4 represent principal quantum number and d- represents azimuthal quantum number (having l- value as 3)

5.Principal, Azimuthal (subsidiary), and magnetic quantum number are the first three because 2 stands for principal, s-for azimuthal (l=0) and magnetic quantum number for s- orbital= 0

6. 10 electrons, because for sublevel with l= 3, is a d-sub-level, and d- can take 10-electrons

7. 32 electrons, using the relationship 2×n^2 for the maximum number of electrons in a shell,

,n= 4 , hence 2×4^2= 32

8. 36 electrons, because n=4 and n= 3 can have the maximum configuration of [Ar]4s^2 3d^10 4p^6

This will sum up to 36- electrons, since Argon has 18 -electrons.

18+2+10+6=36 electrons
