C. An atom of helium has its valence electrons in its first energy level, it wouldn't and can't satisfy the Octet rule as it only has 2 electrons, but with 2, it has a full shell, as the first energy level can hold only 2 electrons.
Answer:
Zirconium
Explanation:
Given that,
Mass number = 92
No of neutrons = 52
Mass number is the sum of the number of protons and neutrons. We can find the number of protons.
92 = 52 + P
P = 40
Atomic number is equal to the number of protons. It means that the atomic no of the element is 40. The element is Zirconium whose atomic number is 40 and mass number is 92.
In the context of the 4ps of the marketing mix, high-tech media options like cell phones and the internet have had a huge impact on products.
The four Ps represent the crucial factors that must be carefully thought out and put into practice in order to properly advertise a good or service. Product, price, place, and promotion make up this list.
The marketing mix is another name for the four Ps. They cover a wide range of aspects that are taken into account when marketing a product, such as what consumers want, and how the good or service satisfies or doesn't satisfy those wants.
Also on how the good or service is perceived in society, and how it distinguishes itself from the competition, and how the business that makes it engages with its clients.

Answer:
A) 2.69 M
B) 0.059
Explanation:
A) We have:
33.8% solute by mass= 33.8 g solute/100 g solution
molarity = mol solute/ 1 L solution
molarity= 
x 
x 
x 
molarity= 2.69 mol solute/L solution = 2.69 M
B) We know that there are 33.8 g of solute in 100 g of solution.
As the total solution is compounded by solute+solvent (in this case, solvent is water), the mass of water is the difference between the mass of the total solution and the mass of solute:
mass of water= 100 g - 33.8 g = 66.2 g
Now, we calculate the number of mol of both solute and water:
mol solute= 33.8 g solute x 
= 0.232 mol
mol H20= 66.2 g H₂O x 
Finally, the mol fraction of solute (Xsolute) is calculated as follows:
Xsolute=
Xsolute= 0.059
According to Henry's law, which was stated in the early 1800's by WIlliam Henry, is that the mass of a solute causes it to absorb more gases into a solution.
