Which statement refers to the quantum mechanical model? A) Electrons move in a circular path about the nucleus. B) Electrons can

lose energy and fall into the nucleus. C) Electrons are in "orbitals", regions of space where there is high probability of being found. D) An electron can move from one circular path to another only when it absorbs or emits energy corresponding to the exact difference between the two energy states.

Answer:

Electrons are in "orbitals", regions of space where there is high probability of being found.

Explanation:

The Wave mechanical model of the atom does not restrict the electrons to certain energy levels only as in the Bohr's model, instead it describes a region around the nucleus called an orbital, where there is a high probability of finding an electron with a certain amount of energy.

Each energy level is composed of one or more orbitals and the distribution of electrons around the nucleus is determined by the number and kind of energy levels that are occupied.

What mechanical and chemical digestion occur in the stomach?
Pavlova-9 [17]

Answer:

See the answe below, please.

Explanation:

In the stomach, during digestion there are two types of:

-Mechanics: the degradation of food occurs, distension of the stomach walls is performed when they arrive, producing the Chyme.

Chemistry: through the participation of enzymes (pepsin activated by hydrochloric acid, which digests proteins in shorter amino acid chains and; gastric lipase that breaks fat giving glycerin products and fatty acids)

If 65.39 g of zinc are mixed with some unknown mass of hydrochloride acid, 136.29 g of zncl2 are formed along with 2.00 g of hyd
zepelin [54]

How much hydrogen chloride acid was used?

72.916 g of hydrochloric acid was used.

Given:

Mass of Zn = 65.39 g

Mass of ZnCl_{2} =136.29 g

Mass of H_{2} = 2 g

Equation:

The chemical equation for the reaction of zinc with hydrochloric acid:

Zn + 2HCl → Zn Cl_{2} + H_{2}

Hydrogen gas is created when zinc combines with hydrochloric acid, which causes the process to bubble ferociously. Another sign that a chemical reaction is taking place is the generation of a gas.

Calculation:

A number of equivalents equate:

Number of equivalents = \frac{given mass}{Molecular Mass} x 1000 x equivalent factor

\frac{x}{36.458} x 1000 x 1 = \frac{136.29}{136.286} x 1000 x 2

x = 36.458 x 2

x = 72.916
