Use the equation q=ncΔT.
q= heat absorbed our released (in this case 1004J)
n= number of moles of sample ( in this case 2.08 mol)
c=molar heat capacity
ΔT=change in temperature (in this case 20°C)
You have to rewrite the equation for c.
c=q/nΔT
c=1004J/(2.08mol x 20°C)
c=24.1 J/mol°C
I hope this helps

Explanation:
its an acidic oxide, it disolves in water to form carbonic acid which is an acid
Answer:
3.5
Explanation:
500*0.175= 8.75 *40/1000=3500/1000=3.5
C is the answer because he wants to know if less force is needed to pull on a slippery surface which reduces friction
