Eleanor wants to show her class a comparison of melting
rates between two different solids when heat is applied. A graph would be more
suitable than a table to show her data because the she can see the trend line
of the effects of melting than the table.
Answer:
1 mol SO2 contains 6.0213*10^23 molecules
6.023*10^24 molecules = 10 mol SO2
Equation
S(s) + O2(g) → SO2(g)
1 mol S reacts with 1 mol O2 to prepare 1 mol SO2
To prepare 10 mol SO2 you require : 10 mol S plus 10 mol O2
And that is the answer to the question
If you want a mass :
Molar mass S = 32 g/mol You require 10 mol = 320 g
Molar mass O2 = 32 g/mol :You require 10 mol = 320 g
Answer is c photosynthesis
It is 95% ethanol and 5%water
I’m pretty sure hope you get it right!
:)
1 mole Zn ---------- 6.02 x 10²³ atoms
0.750 moles Zn ----- ?
atoms = 0.750 * ( 6.02 x 10²³ / 1 )
= 4.515 x 10²³ atoms
hope this helps!
