Molecular formula of aspartame = C14H18N2O5 Molecular mass of aspartame = ( 12 * 14 ) + ( 1 * 18 ) + ( 14 * 2 ) + ( 16 * 5 ) = 294 The number of moles = 10 / 294 = 0.034 mole
When heating water, it takes energy to heat the water molecules that can overcome the forces of attraction between them( hydrogen bond ) and thus the water molecules are separated from each other and turn into a gaseous state
CO(g) + 1/2 O2(g) ــــــــــــــــــــــــــــــــ> CO2(g)
The ionization energies for removing successive electrons from sodium are 496 kJ/mol, 4562 kJ/mol, 6912 kJ/mol, and 9544 kJ/mol. The great jump in ionization energy after the first electron is removed indicates what?
Indicate that the outer shell of sodium atom contain only one electron .which removing easily ,so sodium atom charge in chemical reaction is Na+1
Density = mass / volume Concentration = mass of solute / molecular wieght * volume of solution if Concentration Increase so the mass will be Increase then the Density will be Increase .
