Answer:
Different types of isotopes are used for different materials or objects. For radiometric dating, uranium-235 is considered best for it while carbon-14 is used for dating of rocks. It is also used for dating of wood samples.
Explanation:
Carbon-14 and uranium-235 are used for different materials or objects for measuring the age of these materials. These two isotopes are radioactive in nature which means they emit gamma radiations which allow us to find the age of different objects. Carbon-14 has a low half life so it can be used for those objects which are present before thousands of years while uranium-235 is used for materials which are millions of years old due to high half life.
Saturated solution is when a solution has dissolved as much as it can
Answer:
By watching the movement of cirrus clouds you can tell from which direction weather is approaching. When you see cirrus clouds, it usually indicates that a change in the weather will occur within 24 hours. Cirrostratus clouds are thin, sheetlike high clouds that often cover the entire sky.

The given question is incomplete. The complete question is :
What is the net ionic equation for the following reaction?

Answer : The spectator ions are
and 
Explanation:
Neutralization is a chemical reaction in which an acid and a base reacts to form salt and water.
Spectator ions are defined as the ions which does not get involved in a chemical equation or they are ions which are found on both the sides of the chemical reaction present in ionic form.
The given chemical equation is:

The ions which are present on both the sides of the equation are barium and chromate ions. and hence are not involved in net ionic equation.
Hence, the net ionic equation is
