Bohr suggested, that there are definitive shells of particular energy and angular momentum in which an electron can revolve. It was not in Rutherford's model
Answer:
390
Explanation:
Specific heat capacity= heat/mass × temperature
Remember you convert gram into kilogram and 1 gram =0.001 kilogram
Hydrogen + oxygen --> water
2,1g + 16,8g = x
x = 18,9g
Ok the ML (the 3rd number) is not legit because the ML value can only be from -L to L (the second value)
Answer:
1) Moles of CO 2 = Given mass / Molecular mass of CO 2 = 4.4 / 44 = 0.1 mole. 2) Molecules of CO2 in 0.1 moles of CO2 = 0.1 x 6.023 x 10 23 = 6.023 x 10 22 molecules 3) 44 gram (molecular wt of CO 2) contains 2 moles atom of oxygen therefore 4.4 gram of CO2 will contain = 2 /44 *4.4 = 0.2 moles atom of Oxygen.
