I know the answer to your question but if you want me to answer this question first, I need your help with my question "How do I solve number 12? Quick please I need help ASAP!!!"
<u>Answer:</u> The equilibrium partial pressure of NO is 0.0034 atm
<u>Explanation:</u>
For the given chemical equation:
The expression of 
for above equation follows:
We are given:
Equilibrium partial pressure of 
= 0.0159 atm
Equilibrium partial pressure of NOBr = 0.0768 atm
Putting values in above equation, we get:
Hence, the equilibrium partial pressure of NO is 0.0034 atm
1) moles = mass/mR
CaCO3 Mr = 40 + 12 + (16×3)
= 52 + 48
= 100
mass = 15
so the moles would be 15 ÷ 100
which is 0.15 moles of CaCO3
2) moles = mass ÷ Mr
Mr of Al2O3 = 27 + (16×3)
= 27 + 48
= 75
mass = 204
so the moles would be 204/75 which is 2.72 moles of Al2O3
Answer:
I think the density of the object determines if it floats or sinks
Conduction causes it to become hot, the molecules in the hot soup want to be on the cold spoon so they move to it, making the spoon hot.
