Seems right, but if it’s just asking for one i would pick B
Answer:
b. CH₂Cl₂ is more volatile than CH₂Br₂ because of the large dispersion forces in CH₂Br₂
Explanation:
CH₂Cl₂ is more volatile than CH₂Br₂ (b.p of CH₂Cl₂ = 39,6 °C; b.p of CH₂Br₂ = 96,95°C). Thus, c. and d. are FALSE
Dipole-dipole interactions in CH₂Cl₂ are greater than the dipole-dipole interactions in CH₂Br₂ because Cl is more electronegative that Br (Cl = 3,16; Br = 2,96). But this mean CH₂Cl₂ is less volatile than CH₂Br₂ but it is false.
There are large dispersion forces in CH₂Br₂ because Br has more electrons and protons than Cl. Large disperson forces mean CH₂Br₂ is less volatile than CH₂Cl₂ and it is true.
I hope it helps!
Yes it could be calculated everything that has numbers like those you calculate them and see what u get
Answer:
1809.9 Grams of Calcium Nitrate
Explanation:
Calcium Nitrate Ca(NO3)2
Molar Mass: 164.086g/mol
Given: 11.03 mol of Ca(NO3)2 x 164.086g/mol = 1809.9 Grams of Calcium Nitrate
