Hello!!
Please remember that density=mass/volume.
In this case, we have the same mass for the feathers and the gold (1 pound).
So, if the mass is the same for both we have:
Df*Vg=Dg*Vf where f means feathers and g means gold.
In this case we see density is inversely related to volume. Both materials have the same mass. So which one have a bigger volume?
For this take a pound of feathers and submerge in a known volume of water. Note the displacement. Do the same for a pound of gold. Whichever has the smaller displacement, has the greater density.
In this case, Gold has the greatest density.
Answer:

Exothermic means loss of heat to combine 2 elements
Ok....... why don’t u do

Answer:
See below ~
Explanation:
The respective pairs are :
× Ribose ⇒ The sugar of RNA
× Double helix ⇒ Structures of DNA
× Watson & Crick ⇒ Proposed the double helix model
× Base pair ⇒ Adenine - Thymine pair
× Cytosine ⇒ The nucleotide pair of Guanine
Elements and compounds are two types of substances ( I think). An element is any material made up of one type of atom- there could be multiples of this atom though for example oxygen which has a formula of 02. A compound is a substance made up of more than one type of atom for example H2O
Hope this helped! :)
