These could all go either way, hardness and other special properties are what I'm guessing would be the most accurate in determining the kind of material.
luster, cleavage, streak, and color can all be affected by other factors. but I guess cleavage would also be accurate. so I guess hardness special properties and cleavage would be the most reliable.
The net ionic equation for the reaction that occurs when small amount of HCl are added to HoCl/ NaOcl Buffer solution is written as follows
H+ + OCl - -----> HOcl
Just remember how many electrons can each sublevel hold.
S=2
P=6
D=10
Since we have 10 for atomic number, we can assume we have 10 electrons
1S2
2S2
2P6
The rest have zero because we already have 10 (2+2+6=10)
Answer: Atomic mass is associated with the number of neutrons and protons that are present in a particular nucleus of an element. Atomic number is usually the number of protons present in an element's nucleus. It is the average weight of an element. It is the total number of nucleons in the atom's nucleus.
Assuming there were errors in atomic masses, Mendeleev placed certain elements not in order of increasing atomic mass so that they could fit into the proper groups (similar elements have similar properties) of his periodic table.
- Have a nice day :)
<span> 2 moles of N2O5 = 4 moles of NO2
2.4 mol N2O5/1 X 4 mol NO2/2 mol N2O5 (this way you can cross out the N2O5 mol and just be left with NO2 mol)
2.4 X 4 = 9.6
9.6/2 = 4.8
4.8 mol NO2 are formed</span>
