I believe that the answer is element
Well, there is kinetic energy when the object is in motion. But it will stop eventually because that energy is converted into thermal energy, or heat.
5 g is bigger than 43 mg.
I hope this is right, I apologize if I'm wrong.
Answer:
5 degrees required for ice
Answer:
0.362 moles
Explanation:
Mass of butane = 21g
Molar mass of carbon = 12g / mol
Molar mass of hydrogen = 1g/mol
Molar mass of butane ? = [(12*4) * (1*10)]
Molar mass of butane = 58g / mole
Number of moles = mass of molecules / molar mass of molecule
Number of moles = 21 / 58
Number of moles of butane = 0.362 moles
The number of moles in 21g of butane is 0.362 moles
