Why did J. J. Thomson reason that electrons must be a part of the atoms of all elements? Charge-to-mass ratio of electrons was the same, regardless of the gas used.
Cathode rays are negatively-charged particles.
An electron is 2000 times lighter than a hydrogen atom.
Cathode rays can be deflected by magnets.

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

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.

explanation: no but i do not usually comment

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
