When alpha particles are used to bombard gold foil, most of the alpha particles pass through undeflected. This result of the experiment indicates that most of the volume of a gold atom consists of unoccupied spaces. This was an experiment done by Ernest Rutherford which allowed him to verify the presence of the a small region positive charge in an atom which is called as the nucleus of the atom. Most of the alpha particles pass through the foil while a certain amount were deflected. Those that pass through confirmed that there is a large area that is unoccupied in an atom.
12000 ml would be d to my calculations but then u can 12
Answer:
it's a covalent compound
Explanation:
Two non metals are bonded to together
The mass of 22.4 L of H2O at STP IS 18.0 grams
calculation
mass = moles x molar mas
Calculate the moles of water at STP
At STP 1 mole =22.4 L
what about 22.4 l of H2O
by cross multiplication
1mole x22.4 L/22.4 L = 1 mole
molar mass of water = (1 x2) + 16 =18 g/mol
moles is therefore = 8 g/mol x 1 mol = 18 grams
A - Na Na + but that’s it
