Explanation:
First, let's review the ideal gas law, PV = nRT. In this equation, 'P' is the pressure in atmospheres, 'V' is the volume in liters, 'n' is the number of particles in moles, 'T' is the temperature in Kelvin and 'R' is the ideal gas constant (0.0821 liter atmospheres per moles Kelvin).
Answer:
object b by 0.42g/cm cubic
Explanation:
density = mass/volume
object a =10/8
=1.25g/cm^3
object b = 10/6
=1.67g/cm^3
therefore object b has greater density and by 0.42g/cm^3 (1.67- 1.25)
Dehydration means (removal of water molecule) and in this case a double bond is formed by removal of H and OH from two vicinal (neighboring) carbons, this occurs by protonation then lose of water molecule then lose of H⁺ (we have to add H⁺ from acid at the beginning due to OH⁻ is bad leaving group)

Answer:
The correct answer is Na3N
Explanation:
Sodium nitride (a neutral salt) is composed of an atom of Sodium (Na) and 2 of Nitrogen (N) with the oxidation number +5, requiring 3 electrons to complete its octet.
