(b) In the periodic table, the transition elements and Group 1 elements are 6 points metals. Some of the properties of two transition elements and two Group
1 elements are shown in the table below. Use your own knowledge and the
data in the table above to compare the chemical and physical properties
of transition elements and Group 1 elements. (6 marks so ensure you write
enough points) *

How did planetesmals form planets? a. they broke apart into smaller chunks. b. they collided and stuck together. c. they cooled and pulled ice together. d. they began to rotate.

The peak wavelength for the blackbody curve of a star is in the uv range. assuming the radiation from this star can reach earth, would you be able to see it?

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.
