Henry Moseley developed the concept of atomic numbers.
Answer:
Argon 7.89693x10^25 atoms
Gold 4.1949252x10^25 atoms
Carbon Monoxide 34.55149 moles
Potassium oxide 1.6 moles
Calcium 4.4969x10^24 atoms
Explanation:
Its done with dimensional analysis i can not put the full work here because it would look to sloppy
Answer:
lAs can be seen from the chemical equation, each mole of
F
e
2
C
O
3
needs 3 moles of
C
O
. If 30 moles of
C
O
are used, only 10 moles of
F
e
2
C
O
3
can be reduced, generating 20 moles of
F
e
, corresponding to 1117 grams of iron.
Answer:
Hypothesis and Data Collection
Part A-i think the glass with cold water will have more of a air bubble effect then the one with hot water
Part B-The glass with cold water is having more of a reaction but the water level in both of them are the same
Part C-yes, the glass with cold water had more of a reaction then the one with hot water
Analyze and Extend
Part A-yes, the glass with cold water had more of a reaction then the one with hot water
Part B-Becuase the reaction in the cold water was greater than the one in the hot water we can come to the conclusion that CO2 has a higher solubility in cold water
Part C-the soda that was left in the refrigerator wil have more "fizzing and bubbles" becuase it has higher solubility then the one left in the hot sun
Part D-There is now too much CO2 in the atmosphere and the tempertaures will continue to increase (this is why the summer time is hotter then the rest of the year)
Ik i was late to answer this but can you please give me brainliest
