which conversion factor do you use to first calculate the number of grams of CO2 produced by tge reaction of 50.6 CH with O2? The equation for the complete combustion of methane is: CH4 (g) + 2o2 (g) ---> CO2 (g) +2H2o (l) a. 2 mol O2/1 mol CO2 b. 1 mol C...

Imagine a circle with a diameter of 2km.if this represents an atom ,which answer would best represent the nucleus?choose the correct answer:a table tennis ball(diameter;2cm)atennis ball(diameter;7cm)avolley ball(diameter;20cm)a soccer ball(diameter;25cm)

The energy-separation curve for two atoms, a distance, r, apart is: U(r)=−A/r^m+B/r^n first I have: ((A*m)/(B*n))^(1/(m-n)) Derive and expression for the stiffness of the bond at the equilibrium spacing, in terms of A, B, m, n, and r0. S=dF/dr at r=r0:

r_0=((A*m)/(B*n))^(1/(m-n))
