During the motion of the slinky in a transverse wave, what do the particles of the slinky coil do? the slinky particles move side to side

the slinky particles move up and down

the slinky particles move from the hand down the wave to the block

1. 1 mole of anything contains 6.022x10^23 pieces  

d  

2. a  

3. c, number  

5. 1.24x10^24atoms / 6.022x10^23atoms/mole = 2moles h2 atoms  

6. fe2br3 mass = 2moles x mass fe + 3 moles x mass br  

molar mass = grams / number of moles = g/mole  

to find moles = g / molar mass  

to find mass = g = molar mass / moles

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.

the answer is 0.8m.
