Using the same anchor points, he determined the freezing temperature for water to be 0 degree and the boiling temperature 100 degrees. The Celsius scale is known as a Universal System Unit. It is used throughout science and in most countries.
In Rutherford's gold foil experiment, some of those particles were deflected back towards him and off to the side. This told him that the protons and electrons were not evenly dispersed. However, the particles that did pass through did so because the protons are located in a concentrated area in the center of the atom, and the electrons are dispersed in the empty space around it. At least, that is what Rutherford determined
The volume in liters occupied by 22.6 g of I₂ gas at STP is 1.99 L (answer A)
<u><em>calculation</em></u>
Step: find the moles of I₂
moles= mass÷ molar mass
from periodic table the molar mass of I₂ is 253.8 g/mol
moles = 22.6 g÷253.8 g/mol =0.089 moles
Step 2:find the volume of I₂ at STP
At STP 1 moles =22.4 L
0.089 moles= ? L
<em>by cross multiplication</em>
={ (0.089 moles x 22.4 L) /1 mole} = 1.99 L
I feel like it's the all the above but if it had to be one choice then I think it's the type of climate from which it came.
