Option 2, Br. I'll go over why all other three options are incorrect.

Option 1 - Krypton is a Noble gas, and so it doesn't need to accept electrons since it has an octet.

Option 3 and 4 - Both Calcium and Barium are alkaline earth metals, and give away electrons, since they only have 2.

qaws [65]
Majority can such as hydrogen H and oxygen O forming water H2O but uranium having extra neutrons to form plutonium and beyond simply can't because it will not last for a fraction of a second or spiral out of control and violently react like the little boy and the fat man (a uranium and plutonium nuclear weapon) so yes and no

A cleaning bottle contains 83.1 g of ammonia. How many molecules of ammonia are in the bottle?
Tasya [4]

Answer:

2.94 x 10^2^4

Explanation:

First we need to find out how many moles of ammonia there are, using the formula: Mass = mr x moles.

We know the mass is 83.1g, now we need to find the mR of ammonia - NH3.

N = 14, H = 1, so 14 + (3x1) = an mr of 17.

Moles = mass/ mr = 83.1/17 = 4.8882

Now we can multiply the moles by avogadro's constant to find the number of molecules:

4.8882 x (6.02 x 10^2^3 ) = 2.94 x 10^2^4 molecules of ammonia

What is the molar mass of AuCl3?
alexira [117]

Explanation:

Molar mass is the the mass of one mole of a substance and is expressed in g/mol. Gold atomic mass is 196.96657, chlorine has 35.453. Hence, molar mass of AuCl3= atomic number of Gold + atomic mass of chlorine × (number of atoms of chlorine in AuCl3). Molar mass of AuCl3 = 196.96657 + (35.453 × 3).
