Answer:
Their melting and boiling points of alkanes are relatively low. The higher the molecular weight (the greater the number of carbons), the higher the boiling point.
Find volume of pillow
L=78cm
B=55cm
H=25cm
Now
Mass=5.5kg
Density of water=1000kg/m^3
As it is less than density of water it will float on water
Answer:
B) atom of Xenon
Explanation:
Xenon is already stable alone, because it has a complete octet, or 8 electrons. This graph is not an ion because it shows xenon is its default state, consisting of 8 electrons.
