Answer:

Respiration

Explanation:

The carbon exchange between plants and the atmosphere takes place via:

1) Photosynthesis

2) Respiration

Photosynthesis is a process in which the plants take in carbon in the form of CO2 and water and convert it into glucose along with the release of oxygen (O2). The entire reaction requires energy in the form of sunlight.

Respiration, in contrast involves the breakdown of glucose in the presence of O2 to the release the carbon back in the form of CO2, along with the formation of water and energy.

How is the oxidation state of a transition metal determined from the chemical formula ?
Vera_Pavlovna [14]

Answer:

Explanation:

In a chemical formula, the oxidation state of transition metals can be determined by establishing the relationships between the electrons gained and that which is lost by an atom.

We know that for compounds to be formed, atoms would either lose, gain or share electrons between one another.

The oxidation state is usually expressed using the oxidation number and it is a formal charge assigned to an atom which is present in a molecule or ion.

To ascertain the oxidation state, we have to comply with some rules:

  • The algebraic sum of all oxidation numbers of an atom in a neutral compound is zero.
  • The algebraic sum of all the oxidation numbers of all atoms in an ion containing more than one kind of atom is equal to  the charge on the ion.

For example, let us find the oxidation state of Cr in Cr₂O₇²⁻

This would be:  2x + 7(-2) = -2

                          x = +6

We see that the oxidation number of Cr, a transition metal in the given ion is +6.

'Synthetic detergents are better than soaps'. Justify this statement​
Shtirlitz [24]

Answer:

Synthetic detergents can be used for washing purposes even when the water is hard, whereas soaps are not suitable for washing with hard water. This is because of the fact that synthetic detergents can lather with hard water. Hence, Synthetic detergents better than soaps.
