Answer:
Pupa Stage
Explanation:
Silk worm consists of four stages- the adult, the egg, the larva (caterpillar) and the pupa stage.
Answer:
Hope this helps:)
Explanation:
The values for the table entries are reduction potentials, so lithium at the top of the list has the most negative number, indicating that it is the strongest reducing agent. The strongest oxidizing agent is fluorine with the largest positive number for standard electrode potential.
Elemental fluorine, for example, is the strongest common oxidizing agent.
Lithium metal is therefore the strongest reductant (most easily oxidized) of the alkali metals in aqueous solution. The standard reduction potentials can be interpreted as a ranking of substances according to their oxidizing and reducing power
Answer: Molar mass of 
is 249.68 g/mol.
Explanation:
Molar mass is the mass of 1 mole of the molecule. It is calculated by adding masses of all the atoms in the given molecule.
contains one atom of copper , 1 atom of sulphur, 9 atoms of oxygen and 10 atoms of hydrogen
Mass of copper = 63.5 g/mol
Mass of sulphur = 32.06 g/mol
mass of oxygen = 16.00 g/mol
Mass of hydrogen = 1.008 g/mol
Thus mass of = 63.5(1)+32.06(1)+16.00(9)+1.008(10)=249.68 g
Molar mass of is 249.68 g/mol.
The substance produced by iron reacting with oxygen in the air is rust.
