Answer: The chemical formula for aluminium nitrite is $Al(NO_2)_3$

Explanation:

The given compound is formed by the combination of aluminium and nitrite ions. This is an ionic compound.

Aluminium is the 13th element of periodic table having electronic configuration of $[Ne]3s^23p^1$ .

To form $Al^{3+}$ ion, this element will loose 3 electrons.

Nitrite ion is a polyatomic ion having chemical formula of $NO_2^{-}$

By criss-cross method, the oxidation state of the ions gets exchanged and they form the subscripts of the other ions. This results in the formation of a neutral compound.

So, the chemical formula for aluminium nitrite is $Al(NO_2)_3$

What is the de Broglie wavelength (in nm) of a proton of traveling at 3.18% of the speed of light?

gulaghasi [49]

Answer is: de Broglie wavelength of a proton is 3,4·10⁻⁵ nm.
v(proton) = 0,038 · 3·10⁸ m/s.
v(proton) = 1,14·10⁷ m/s; speed of proton.
m(proton) = 1,67·10⁻²⁷ kg.
h = 6,62607004·10⁻³⁴ m²·kg/s; Planck constant.
λ(proton) = h / m(proton) · v(proton).
λ(proton) = 6,62607004·10⁻³⁴ m²·kg/s ÷ (1,67·10⁻²⁷ kg · 1,14·10⁷ m/s).
λ(proton) = 3,48·10⁻¹⁴ m · 10⁹ nm/m = 3,4·10⁻⁵ nm.

Compared to CH4,NH3 has:

vitfil [10]

a) NH₃ molecules have stronger intermolecular attractions than CH₄ molecules.

Explanation:

Ammonia molecules have stronger intermolecular attractions compared to methane.

Ammonia molecules have london dispersion forces and hydrogen bonds between their molecules.

Methane molecules have only london dispersion forces in their structure.

hydrogen bonds are very strong attractive forces between molecules in which the hydrogen of a molecule is attracted by a more electronegative atom of another usually oxygen, nitrogen and fluorine.
London dispersion forces are weak forces of attraction between heteronuclear atoms.

Which is a pure substance? soda gasoline salt water carbon dioxide

hram777 [196]

Answer: Carbon dioxide is a pure substance.

Explanation: A pure substance is defined when a substance has a single type of molecule. If more than 1 type of molecule is present in a substance, then it is considered as a mixture.

Soda is basically a mixture of water and carbon dioxide. More than 1 type of molecule is present.

Gasoline is a mixture of may gases. More than 1 type of molecule is present.

Salt water contains salt and water molecules, hence it is considered as a mixture.

Carbon dioxide has only 1 type of molecule which is $CO_2$ molecules. Hence, it is a pure substance.
