Answer:
The answer is 2,200ºC
Explanation:
I took the assignment for Edge, I don't think I can send the image because it might pick up on that and get reported, sorry!
The only other rationale that I have is that it's boiling because the graph shows that it's at a constant temperature/rate at 2,200ºC for quite a while. Typically when something boils, it stays at that constant rate of boiling, unless you turn the temperature up or it's finally able to peak..?
Answer:
Assuming the product is AlCl3
Assuming its 1008 g of metalic Al
It will yeld 4234 g of aluminium chloride.
Explanation:
Al molar mass is 26.98 g/mol, so in 1008 g of Al there is 37.36 mols of Al
The stoichometry ratio between Al and AlCl3 is 1:1, so 37.36 mols of Al would form 37.36 mols of AlCl3 if the reaction were complete, but only 85% yelds, so 1008 g of Al makes up to 0.85x37.36 mols of AlCl3 (31.76 moles)
AlCl3 molar mas is 133.33 g/mol, so 31.76 moles has 4234 g
It’s a liquid because it can form any shape to fit container but the amount of liquid always stayed the same unless dropped some.
#2
They are ordered by increasing number of protons (aka atomic number)
Answer:
6
Explanation:
The maximum number of electrons in the orbitals of sub-levels are given as:
for s-sublevel we have two electrons and one orbital
p-sublevel we have six electrons and three orbitals
d-sublevel we have ten electrons and five orbitals
f- sublevel we have fourteen electrons and seven orbitals
The second energy level is represented by the p-sub-level and it will accommodate 6 electrons.
