the balanced equation for the reaction is as follows
2 Al + 3 Cl₂ ---> 2 AlCl₃
molar ratio of Cl₂ to AlCl₃ is 3:2
mass of Cl₂ reacted is - 11.5 g
number of moles of Cl₂ reacted - 11.5 g / 71 g/mol = 0.162 mol
when 3 mol of Cl₂ reacts - 2 mol of AlCl₃ is formed
therefore when 0.162 mol of Cl₂ reacts - 2/3 x 0.162 mol = 0.108 mol of AlCl₃ is formed
the molar mass of AlCl₃ is 133 g/mol
mass of AlCl₃ formed is - 0.108 mol x 133 g/mol = 14.4 g
mass of AlCl₃ formed is 14.4 g
Given an unknown mixture consisting of two substances, a scientist can determine whether a specific mixture is a true solution, a colloid, or a suspension by passing a light through the mixture. They are distinguished by the Tyndall Effect. If the mixture is a solution, light just pass through the mixture. The light does not reflect. If the mixture is a colloid, then light is dispersed or reflected due to the colloidal particles. If the mixture is a suspension, light cannot pass through.
Answer:
No.
Explanation:
They all are in sync.
Ex. 1 Hydrogen, 2 Helium, etc.
The atomic number is the number of Protons on the nucleus of the atom, whereas the mass number of some isotope is the mass of the protons plus the mass of the neutrons. That's the difference between isotopes: number of neutrons.
Ask me if you need any help ;)
I think we need an attatchment-
