Please help me solve this!

Answer : The image is attached below.

Explanation :

For :

Molar mass, M = 48 g/mol

Mass, m = 24 g

Moles, n =

Number of particles, N =

For :

Molar mass, M = 17 g/mol

Mass, m = 170 g

Moles, n =

Number of particles, N =

For :

Molar mass, M = 38 g/mol

Mass, m = 38 g

Moles, n =

Number of particles, N =

For :

Molar mass, M = 44 g/mol

Moles, n = 0.10 mol

Mass, m =

Number of particles, N =

For :

Molar mass, M = 46 g/mol

Moles, n = 0.20 mol

Mass, m =

Number of particles, N =

For :

Molar mass, M = 20 g/mol

Number of particles =

Moles, n =

Mass, m =

For :

Molar mass, M = 44 g/mol

Number of particles =

Moles, n =

Mass, m =

For unknown substance:

Number of particles =

Mass, m = 8.5 g

Moles, n =

Molar mass, M =

The substance is .

they are both synthetic elements

explanation:

d

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.
