Each number is defined by the number of protons.
pentagon [3]3 years ago

Answer:

The atomic number of an element is equal to the number of protons in each atom and defines the element. For example, all carbon atoms contain 6 protons in their atomic nucleus; so the atomic number of carbon is 6.

What does the number of an element represent?

The atomic number or proton number (symbol Z) of a chemical element is the number of protons found in the nucleus of every atom of that element. The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus.

Assume reaction N (g )space plus O (g )rightwards arrow N O (g )occurs in high layers of the atmosphere. What is the H subscript
8090 [49]

Answer:

Kindly check the explanation section.

Explanation:

From the description given in the question above, that is '' H subscript f to the power of degree of the reaction" we have that the description matches what is known as the heat of formation of the reaction, ∆fH° where the 'f' is a subscript.

In order to determine the heat of formation of any of the species in the reaction, the heat of formation of the other species must be known and the value for the heat of reaction, ∆H(rxn) must also be known. Thus, heat of formation can be calculated by using the formula below;

∆H(rxn) = ∆fH°( products) - ∆fH°(reactants).

That is the heat of formation of products minus the heat of formation of the reaction g specie(s).

Say heat of formation for the species is known as N(g) = 472.435kj/mol, O(g) = 0kj/mol and NO = unknown, ∆H°(rxn) = −382.185 kj/mol.

−382.185 = x - 472.435kj/mol = 90.25 kJ/mol
