0.5 litres contain 1.1 moles
therefore 1 litre will have= 1*1.1/0.5
             molarity=2.2M

Answer:

The correct answer is 2.2 mol/L

Explanation:

Molarity of a solution is used to determine the concentration of that solution. It is mathematically expressed as

Molarity (M) = number of moles ÷ volume (in liters or dm³)

The unit for molarity is mol/L or mol/dm³ or M

From the question, number of moles is <u>1.1 moles</u> and the volume is <u>0.5 liters</u>.

Hence,

Molarity = 1.1 ÷ 0.5

Molarity = 2.2 mol/L

What happens to the do Broglle wavelength of an electron If its momentum ls doubled?​
algol13
Answer:
The De Broglie wavelength decreases when the momentum increases
Explanation:
The De Broglie wavelength of a particle (or any object) is given by

where
h is the Planck constant
p is the momentum of the object
As we can see, the wavelength is inversely proportional to the momentum of the object: therefore we can say that, if the momentum increases, the De Broglie wavelength will decrease.

Democritus was the first to propose the idea of the atom. He said the atom was just this tiny, solid sphere. However, he used no scientific evidence to support his claim, so a guy named John Dalton did some experimenting and basically backed up Democritus' claim with evidence. Then, a guy named J.J. Thompson came along and said the atom was not solid and that is consisted of tiny negatively charged particles(electrons) and he came up with the Plum Pudding model which is just a tiny sphere with a punch of random scattered dots in it. After that, Ernest Rutherford did experiments and found that the tiny sphere is made up of mostly empty space with a tiny, dense, positively charged sphere inside of it, and the negatively charged particles just randomly float around it. Neils Bohr then said that the electrons take specific, circular, evenly spaced paths. Then, finally, we come to the Quantum Mechanical Model which is the one accepted today. This model basically vetos Bohr's idea and has a nucleus inside of an electron cloud, which is where the electrons are found.

Do ionic compounds or covalent compounds conduct electricity
Liula [17]

None because Covalent compounds don’t conduct electricity because they are formed between the non metal atoms by sharing of electrons. The Covalent compounds haves no free electrons and also no ions and hence they do not conduct electricity. That is why they do not conduct electricity.
