In the coordination compound [Cr(NH3)2(en)Cl2]Br2, the coordination number (C.N.) and oxidation number (O.N.) of the metal atom,
erma4kov [3.2K]

The coordination number (C.N.) is 6 and oxidation number (O.N.) is +4 of the metal atom.

C.N. = 6; O.N. = +4

<h3><u>What </u><u>is Co-ordination number ?</u></h3>
  • The coordination number, also known as ligancy, of a central atom in a molecule or crystal in chemistry, crystallography, and materials science refers to the quantity of atoms, molecules, or ions bound to it.
  • A ligand is the ion, molecule, or atom that surrounds the center ion, molecule, or atom.
  • The number of atoms, ions, or molecules that a central atom or ion in a complex, coordination compound, or crystal holds as its closest neighbors.
<h3><u>What is Oxidation number ?</u></h3>
  • The total number of electrons that an atom acquires or loses to establish a chemical connection with another atom is known as the oxidation number, also known as the oxidation state.
  • Each atom involved in an oxidation-reduction reaction has an oxidation number that represents how many electrons it may take, give, or share.

alukav5142 [94]

Answer:

photosynthesis.

The green disks in Elodea plant cell under a microscope represent specialized plant cell organelles, known as chloroplasts. Chloroplasts are double-membrane bound cell organelles that contain green pigments or chlorophyll molecules.

These pigments trap the energy from solar light, which is used by the plants for the process of photosynthesis to make their food.

Household sugar sucrose has the molecular formula c12h22o11. what is the carbon in sucrose by mass
3241004551 [841]
Answer:
            %age of Carbon is 42.10 %.

Explanation:
                   In order to find the %age of elements present in a molecule we will use following formula,

%age of Element  =  (Mass of Element / Mass of Molecule) × 100

The molecular mass of Sucrose is.

                                =  (12)12  +  (1)22  +  (16)11
Where;
            12  =  Atomic mass of Carbon

              1  =  Atomic Mass of Hydrogen

            16  =  Atomic Mass of Oxygen

                                  =  144  +  22  +  176

                                  =   342 g/mol
%age of C;
                                  =  (144 / 342) ×100  =  42.10 %

%age of H;
                                  =  (22 / 342) ×100    =  06.42 %

%age of O;
                                  =  (176 / 342) ×100  =  51.46 %

The chemical formula for the ionic compound formed when elements of ca and n react is
LiRa [457]
When carbon reacts with nitrogen, the product is called carbon nitride. Carbon has a plus two charge while nitrogen has a -3 charge. The product is a result of the exchange of the charges that reflects on the subscripts of the elements. Hence, the chemical formula is c. Ca3N2.
