20/45=0.4*100= 44.4 so the answer is..................................................
Answer: 44.4%
Expansion work against constant external pressure: w=-pex Δ Δ V 3. The attempt at a solution . I tried following that. Because Vf>>Vi, and Vf=nRT/pex, then w=-pex x nRT/pex=-nRT (im assuming n is number of moles of CO2?). 1 mole of CaCO3 makes 1 mole of CO2, so plugging in numbers, I get 8.9kJ, although I dont use the 1 atm pressure at all
Answer:
Potential
Explanation:
Potential difference is otherwise known as voltage. With no voltage flowing through a conductor a current will not flow.
The answer is the 4th option because they don't use oxygen, that's what they produce
