Assignment D Calculate the mass of 1 atom of silver Ag = 108)
1 molecule of carbon4oxide (Co2)
3 A litre (dm³) of Air contains .9.2*10^-4 mole of Argon)
. What is the mass of Argon in 1 dm3 of Air atomic
Mass of Argon (39.9)
A Prospector panning for gold in a river collect
15.0g of pure gold. How many gold of atoms are in this
quantities of Gold. Au=197
5) Calculate the number of mole and molecules in 35.og
of ethylene glycol
(HOCH2CH ₂014 )

Exothermic,  physical change after it is already baked

Ithe undersigned only for use your own email and delete any and copies and of the itself and to be there is a good timewhat does a decrease in temperature indicate about the molecules in a sample of liquid water? decreased chemical energy of the moleculesdecreased kinetic energy of the moleculesincreased chemical energy of the moleculesincreased kinetic energy of the moleculeshow does a sample of helium at 15 â°c compare to a sample of helium at 215 k? the helium at 15 â°c has a higher average kinetic energy than the sample at 215 k.the helium at 15 â°c has lower nuclear energy than the sample at 215 k.the helium at 15 â°c has slower-moving atoms than the sample at 215 k.the helium at 15 â°c has smaller atoms than the sample at 215 k.

The answer is c.  h+  and oh−  react to form water (h2o). i just took the test and i got it right. hope this !
