Which of the following molecules or ions is polar? (20 POINTS)
inessss [21]

Answer:

All of these three are polar molecules or ions

Explanation:

1) CO3 ^2-

It is a polar ion because it consists of one Oxygen atom and three carbon atoms so there is a substantial electroegativity difference between carbon and Oxygen due to which shared electrons are attracted more towards Oxygen creating partial negative charge on it and less towards carbon creating a partial positive charge on it, which makes the overall ion polar.

2) HCN

HCN is a polar molecule because there is substantial electronegativity difference between Carbon and Hydrogen as well as between Carbon and Nitrogen. Due to this negative charge is induced over Nitrogen because electronegativity of Nitrogen is 3.0 and positive charge on Carbon because its electronegativity is 2.5. The overall molecule is polar.

3) NO3^-1

Nitrate ion is also a polar molecule because there are three atoms of Oxygen and one atom of Nitrogen. There is substantial electronegativity difference between oxygen (3.44) and nitrogen (3.0) due to which partial positive charge is created on Nitrogen and partial negative charge created over three Oxygen atoms. The overall molecule is polar.

Hope it helps!

What is the wavelength in meters of a proton (mass = 1.673 x 10-24 g) that has been accelerated to 5% of the speed of light?
Molodets [167]

Explanation:

since it has been accelerated to 5℅ of the sleec of light then

v= 5/100 × (3× 10^8)

after getting velocity you'll substitute the values in the formula

de Broglie wavelength= h/mv

don't forget to change the grams in mass to kg

aorry I don't hav my calc with me
