Which of the following about a balanced chemical reactions is
gavmur [86]

Answer:

A balanced chemical equation must always include coefficients on every reactant and product.

Explanation:

<u>A balanced chemical equation does not need to include coefficients on every reactant and product.</u>

For example, below is a balanced chemical equation in which the reactants and the products have no coefficients whatsoever:

NaOH(aq) + HCl (aq) -----> NaCl (s) + H2O (l)

<em>Of course, a properly written chemical equation must include the states of matter of all the substances in the reaction and the number of atoms of each element must balance both in the reactant and product sides of the equation. Generally, a balanced chemical equation must obey the law of conservation of matter which opines that matter can neither be created nor destroyed but can only be converted from one form to another. </em>

Hence, that a balanced chemical equation must always include coefficients on every reactant and product is not true.

Neils Bohr published his model of the atomic structure in 1913. He introduced the theory of electrons traveling in orbits around
matrenka [14]

Answer:

A)  the number of electrons in the outer shells.

Explanation:

The Bohr's model of the atoms shows that electrons orbits the nucleus in energy levels that are discrete and quantised. Orbital electrons are pulled by the nucleus. The nuclear pull is strongest on the shells closer to the nucleus and weakest as we reach the outermost sphere.

From this model, we see that chemical properties are governed by how much electrons an atom is ready to lose from its outermost shell in which the energy is the lowest. It is the electrons in the outermost shell or valence shell that determines how atoms would behave chemically.
