Answer:
B. Excited state
Explanation:
Energy levels higher than the ground state are called the excited states. This concept is based on the premise that electrons can move round the nucleus in certain permissibe orbits or energy levels.
The ground state is the lowest energy state available to the electron. This is usually the most stable state.
The excited state is any level higher than the ground state. An electron in an energy level has a definite amount of energy associated with it at that level.
Answer:
Detail is given below.
Explanation:
Photosynthesis:
Reactants = Carbon dioxide + water + energy
Products = glucose + oxygen
Chemical equation:
6H₂O + 6CO₂ + energy → C₆H₁₂O₆ + 6O₂
It is the process in which in the presence of sun light and chlorophyll by using carbon dioxide and water plants produce the oxygen and glucose.
water is supplied through the roots, carbon dioxide collected through stomata and sun light is capture by chloroplast.
Cellular respiration:
Reactants = Glucose + oxygen
Products = carbon dioxide + water + 38ATP
Chemical equation:
Glucose + oxygen → carbon dioxide + water + 38ATP
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.

Answer:
Explanation:
Sodium chromate has the chemical formula Na2CrO4, and a molar mass of 161.97 g/mol. It is a salt made of two sodium cations (Na+) and the chromate anion (CrO4-) in which the chromium atom is attached to four oxygen atoms.
