Answer:
Magnetivity and melting point.
Explanation:
Aluminum, steel and tin cans can be separated by two step process of magnetisation and melting point, because the three cans have different magnetic properties.
Steel attract to magnet easily because of it's has magnetic properties and these separate steel from aluminum.
Neither steel and aluminum melted at 300°C but Tin melt at that temperature.
<u>Answer: </u>He sorted on the basis of average atomic weights.
<u>Explanation:</u>
Dmitri Mendeleev in 1863 arranged chemical elements in the groups according to their average atomic weights.
He said that elements which have similar chemical properties either have similar atomic weights or their atomic weights increases regularly.
Hence, he collaborated a great work in sorting the elements according to their average atomic weights.
There are 145 centimeters in 1.45 meters.
Answer:
c2h4o2
Explanation:
I am using my cell. This could take a bit
The Empical formula has a mass of
C 12
2H 2
O 16
total = 30
The molecular mass is given as 60 which is 2 times the empirical mass. Therefore multiply each element by 2 in the empirical formula.
You get C2H4O2
