Choose the substance with the highest vapor pressure at a given temperature: a. sis2b. rbclc. ch3sch3d. bf3e. sbh3

correct option is d. BF3

Explanation:

BF3 have lower molecular weight than the SiS2 and CH3SCH3  

but it has a more attractive force

and here dispersion forces is the weakest in BF3  

but CH3SCH3 have dipole forces

In Bf3 have only vanderwaal force and it holds the molecule together in liquid but it not have hydrogen bonding  

and at 0°C  substance is in gas no liquid and no vapour  

so here correct option is d. BF3

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
