Atoms make up everything,
compounds are 2 or more elements joined together chemically and
elements are groups of atoms that mix to create mixtures (2 it more atoms not chemically combined) and compounds.
Answer:
DOUBLE DISPLACEMENT (mutual exachange of ions in aqueous form)
Ca is more reactive than Fe
hence it will displace Fe from ferrous nitrate solution and form Calcium Nitrate and Ferrous Sulphate will be formed
GOOD LUCK WITH THE FUTURE! :)
Scientific names follow a specific set of rules. Scientists use a two-name system called a Binomial Naming System. Scientists name animals and plants using the system that describes the genus and species of the organism. The first word is the genus and the second is the species.planation:
Should remain the same, the volume will decrease.
Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity. We can observe some physical properties, such as density and color, without changing the physical state of the matter observed<span>.</span>
