Chemistry
1 answer:
liubo4ka [24]3 years ago
5 0

Answer:

Explanation:

Density is m/V. Also, 1 liter = 1000 cm^3. So, we get 0.890/(5*1000) = 1.78*10^{-4} g/cm^3. You can convert this to kg/m^3 as well by multiplying it by 10. Depends which one you want.

Which formula represents the compound commonly known as phosphine with iupac name phosphorus trihydride? ph ph2 ph3 ph4
zubka84 [21]

C. PH3 represents a compound commonly known as phosphine, whose IUPAC name is phosphorus trihydride.

<h3>What type of bond is PH3?</h3>

The electronegativity of PH3 found in the Periodic Table of the Period attracts covalent electron pairs and creates covalent bonds. However, because the electrons are not bound, asymmetrical rate distribution occurs. Therefore, PH3 is a polar molecule with a non-polar covalent bond and currently has no polar bond.

<h3 /><h3>What defines a covalent bond?</h3>

A covalent bond consists of sharing one or more electron pairs between two atoms. These electrons are attracted to two nuclei at the same time. Covalent bonds are formed when the difference in electronegativity between two atoms is too small for electron transfer to form ions.

What happens when piece of sodium is exposed to moist air?​
I am Lyosha [343]

Answer:

Sodium reacts with the oxygen in air to form sodium oxide, and traces of yellowish sodium peroxide. ... Probably, the reaction with atmospheric oxygen will be faster, because I have never seen sodium metal turning whitish on exposure, though it does lose its lustre and and reactivity (just the surface).
