Answer is: Ne, P, Ga, Rb.
₁₀Ne 1s²2s²2p⁶. 
₁₅P 1s²2s²2p⁶3s²3p³.
₃₁Ga 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p¹.
₃₇Rb 1s²2s²2p⁶3s²3p⁶3d¹⁰4s²4p⁶5s¹.
Neon has smallest number of orbitals because neon has smallest atomic number (ten electrons), rubidium has largest number of orbitals because rubidium has largest atomic number.

Briefly explain in your own words why the bond angle increases as the number of electron groups decreases
tekilochka [14]

Answer:

i) The bond angle decreases due to the presence of lone pairs, which causes more repulsion on the bond pairs and as a result, the bond pairs tend to come closer. ii) The repulsion between electron pairs increases with an increase in electronegativity of the central atom and hence the bond angle increases.

Which equation represents the combined gas law?
stealth61 [152]

Answer:

P1V1/T1= P2V2/T2

Explanation:

Combined gas law involves Boyle's law and Charles law altogether with the formula of Boyle's law as P1V1=P2V2

formula for charles law as V1/T1=V2/T2

so when combined form P1V1/T1=P2V2/T2

Distinguish between a solution in general and an aqueous solution
Sveta_85 [38]

Answer:

  • What distinguish a solution in general from an aqueous solution is the solvent. A solution in general may contain any solvent, which may be solid, liquid or gas, while an aqueous solution is formed with water as solvent.

Explanation:

A solution in general is a homogeneous mixture in which a substance, named solute, is dissolved, in other substance, name solvent.

Solutions may be in solid, liquid or gas state. There are many kind of solvents. Usually, in a lab you work with liquid solutions. Some liquid solvents are: ethanol, glycerin, hexane, benzene, and water, among many others.

Aqueous solution is a solution where the solvent is water. Of course, the solute may be any one: NaCl, sugar, ethanol, an acid, a base, a salt.

What distinguish a solution in general and an aqueous solution is the solvent.
