A student slides a book over two different surfaces. First, she slides the book across a desk. Next, she slides the same book on the carpet. She exerts the same force onto both books. Which surface would cause a greater change in the velocity of the book? Explain your answer. A. Desk
B. Carpet
C. The change would be the same

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'

you gotta add the following molecules so we can give u an answer

explanation:

plasma - state of matter made up of electrically charged particles
