An oxygen atom is 16x more massive than a hydrogen atom.
You can figure this out by comparing the atomic masses of the two elements: oxygen has an atomic mass number of 16, and hydrogen has an atomic mass number of 1. Thus, an oxygen atom is 16 times more massive than a hydrogen atom.
Answer:
B. The carbons on either side of the double bond are Pointed in opposite directions
Answer:
C)
Explanation:
It's a covalent bond because O and H are both non metals.
Answer:
The figures and parameters to answer this question are not clearly stated, so I will answer it in the closest best way I can.
Explanation:
Molality of alanine = mole / weight of solvent( kg)
= (170×1000)/(89×600)
= 3.18 molal
We know ∆ Tf = Kf × m
Kf = ∆ Tf / molality
= 7.9/3.18 = 2.48 °c.kg.mol-1
Now using the value of cryoscopic constant we calculate can't Hoff factor for Ammonium chloride.
i = ∆ Tf /( Kf × molality of NH4Cl)
= (24.7 × 53.5 × 600) /(2.48 × 170 × 1000)
= 1.8
