Answer:
Oxygen
Explanation:
One mole of atoms of oxygen has a mass of 16 g, as 16 is the atomic weight of oxygen, and contains 6.02 X 1023 atoms of oxygen.
Answer:
B. Below the equilibrium price
Explanation:Price ceiling is the legal price,impose by The Government or Regulatory agencies above which a product should not be sold. It is also a price control mechanism through which the Government and other Regulatory agencies check the excesses of producers and the middle men(Whole sellers and retailers). The price ceiling has to be fixed below the equilibrium price for it to be binding, because businesses are interested mainly for profit maximization.
Answer:
Plants consume carbon dioxide and release oxygen.
Answer: Photosynthesis
Animals consume oxygen and release carbon dioxide.
Answer: Respiration
Let's check Electronic configuration of N in ground state


In hydrogen case

Hence Hybridization


Structure is tetrahedral .
Spare way:-
- Bond pairs==3=>Bonding electrons=6
- Lone pair=1=>Anti bonding electrons=2
Hybridization

- Shape-Tetrahedral .
When a substance is undergoing a change of state, the heat that is been added to the substance at that particular point in time is used to work on the chemical bonds that is holding the molecules of the substance together; the heat is not used to increase the temperature of the substance at that particular point. For instance, in the case of ice, at its melting point the heat supplied is used to break the inter molecular force that is holding the particles of the ice together. When the bonds are completely broken and the ice has to liquid then the temperature of the water will increase.
