Answer:
Physical properties are used to observe and describe matter. Physical properties can be observed or measured without changing the composition of matter. These are properties such as <em>mass, weight, volume, and density.</em>
The amount of energy required to remove one electron from the outermost shell.
Cant really see the picture
Answer:
Dichloromethane
Explanation:
As we know the atomic number given belongs to following elements, i.e.
Atomic # Element M.Mass
1 Hydrogen 1 g.mol⁻¹
6 Carbon 12 g.mol⁻¹
17 Chlorine 35.5 g.mol⁻¹
Also the molecular formula of Dichloromethane is,
= CH₂Cl₂
Putting molar masses of each element,
= (12)₁ + (1)₂ + (35.5)₂
= 12 + 2 + 71
= 85 g.mol⁺¹
Result:
Hence the only possible structure containing 5 atoms is Dichloromethane.
the compound is 2 methyl -1- butane
