Answer:
molar mass of methane CH4
= C + 4 H
= 12.0 + 4 x 1.008
= 12.0 + 4.032
= 16.042g/mol
7.31 x 10^25 molecules x 1 mole CH4 = 121.43 moles
6.02 x 10^23 CH4 molecules
121.43 moles CH4 are present.
Explanation:
not to certain if this is right or not.. but hope it helps!
Answer: 241. 8g. Add the mass of Fe, 3 N masses (because of the 3 outside the parenthesis), and add the 9 O because of the 3 next to it and the 3 outside. This results to 55.846+42.0201+143.946g that equals 241.8g. I hope this helps
Answer:
The wind blows wind energy causing the turbine to turn, the rotating shaft works the pump making mechanical energy.
The motion of water moving up from a well is kinetic energy.
Water in the tank, which is positioned 5 feet above the ground level is potential energy
Explanation:
The wind has in it wind energy which is then used to rotate the turbine shaft which is a form of mechanical work and hence possess mechanical energy
Moving water possesses kinetic energy and when this water is kept at some height it possesses potential energy
