We have to know which do not violet octet rule.
The central atom in SF₄ does not violate the octet rule. the central atom in CF₄ does not violate the octet rule.
As per octet rule, atoms can combine either by transfer of valence electrons from one atom to another or by sharing of valence electrons in order to have an octet in their valence shell.
The central atom S of SF₄ contains 8 electrons in the valence shell. Also, C atom of CF₄ contains 8 electrons in the valence shell.
ICl₄⁻ contains 9 electrons in the outermost shell.
The aluminum sulfate stock solution should the chemist pour out is 219.8 ml
Complete Question
A chemist must prepare 400 mL of 1.00M aqueous aluminum sulfate working solution. He'll do this by pouring out 1.82 mol/L aqueous aluminum sulfate stock solution into a graduated cylinder and diluting it with distilled water. How many mL of the aluminum sulfate stock solution should the chemist pour out?
The aluminum sulfate stock solution should the chemist pour out is 219.8 ml
Given:
V1 = 400ml, M1 = 1 M, V2 = ?, M2 = 1.82 M
Hence, the relation between molarity and volume is as follows.
M1V1 = M2V2
1.00M x 400ml = 1.82 x V2
V₂ = 219.8 ml
Thus, we can conclude that 219.8 ml of the aluminum sulfate stock solution should the chemist pour out.

Answer:
0.61
Explanation:
Flip the sign of the value which is most negative. This means that the metal is undergoing oxidation rather than reduction because it is more reactive. In this case -0.8 becomes 0.8.
Add the two values together
-0.19+0.8
=0.61
I believe it is: The Law of Reflection says that the angle of incidence and the angle of reflection must be equal.

The statement that best describes an advantage of cloning is that it can prevent genetic diseases. DNA cloning is a term used in recombinant DNA technology happens when a DNA strand belonging to one organism is transmitted into a particular type of genetic element having the capacity to self replicate. DNA cloning was developed to offer solutions related to healthcare and medical issues. Illnesses occur mostly because our body fails to produce essential proteins in ample amount is needed, these problems and other inherited problems may be solved using DNA cloning.
