The hydroxyl radical, a fragment of water vapor known as the "atmospheric cleanser", with a chemical formula of OH, has a global

ly averaged number density of ~1×10^6 molecules cm-3 that is fairly constant with altitude. Determine the OH mixing ratio (in ppt) at the surface, where total pressure P ~1 atm, temperature T ~282K, and also at 10 km altitude, where P ~0.260 atm,

Answer:

Check the explanation

Explanation:

The hydroxyl radical, •OH, is the hydroxide ion (OH−) when in neutral form of the Hydroxyl radicals they are extremely reactive (easily becoming hydroxy groups) and as a result are short-lived; however, they form a significant part of radical chemistry. The hydroxyl radical composition is also highly reactive towards oxidative reactions.

Kindly check the attached image below to see the step by step explanation to the question above.

What is the mass of 1.72 moles of BaSO4?
Fiesta28 [93]

Answer: 401.4g

Explanation:

The mass can be calculated by using the following mathematical expression for Moles ,which is:

Moles = Mass / Molar Mass

From the question given, Moles = 1.72, Molar mass of BaSO4 = 233.38g/mol, Mass =?

Making 'Mass' the subject of formula, we get:

Mass = Molar mass x Moles

= 233.38 x 1.72 = 401.4g

How many liters of water would you need to add to 4.36 moles of NaCl to create a 9.4 M solution?
marishachu [46]

Answer:

0.464 L

Explanation:

Molarity (M) = number moles (n) ÷ volume (V)

According to the information given in this question:

number of moles (n) = 4.36 moles

Molarity = 9.4M

Volume = ?

Using M = n/V

9.4 = 4.36/V

9.4V = 4.36

V = 4.36/9.4

V = 0.464 L

Hence, 0.464L of water are needed the volume of water.

In a piece of metal, what holds the atoms together?
alexandr1967 [171]

Answer:

the positive charges of the nuclei and the negative charges of delocalized electrons

Explanation:

The interatomic forces that joins a piece of metal atoms together are the positive charges of the nuclei and the negative charges of delocalized electrons.

This bond type is the metallic bond.

  • The metallic bond is an attraction between the positive nuclei of all the closely packed atoms in the lattice.
  • Also, the electron cloud jointly formed by all the atoms losing their outermost shell electrons.

Merits of modern periodic table?​
ANEK [815]

Answer:

<h3>Merits of modern periodic table:</h3>
  • The wrong position of some elements like argon, potassium, cobalt and nickel due to atomic weights have been solved by arranging the elements in the order of increasing atomic number without changing their own places.
  • The isotopes of some element have the same atomic numbers. Therefore, they find the same position in periodic table.
  • It separates metals from non-metals.
  • The groups of the table are divided into sub groups A and B due to their dissimilar properties which make the study of elements specific and easier.
  • The representative and transition elements have been separated.

Hope this helps...

Good luck on your assignment...
