i say the elephant
Explanation: mainly because its heavier!
It’s c because beryllium is light
Answer:\
1.08 grams
Explanation:
first, we need to find the number of moles
we divide 12.1/22.4=0.54 moles
we multiply the number of moles with the molecular mass 0.54x2=1.08g
The atomic weight of carbon dioxide is about 12.011 + 15.999 + 15.999 = 44.009.
44.009 grams of CO2 = 1 mole of CO2 CO2 = Carbon dioxide
25 ÷ 44.009 ≈ 0.568
About 0.568 moles of CO2
Answer:
7604 kJ
Explanation:
Heat of vaporization for copper = 5069J/g (from my reference source. Use the value you were given).
(1,500grams)*(5069J/g) = 7603500 J, or 7604 kJ The latent heat of vaporization you are given may be slightly lower than the official value of 5069 J/g.
