Gold is a chemical element with symbol Au (from Latin: aurum) and atomic number 79, making it one of the higher atomic number elements that occur naturally. In its purest form, it is a bright, slightly reddish yellow, dense, soft, malleable, and ductile metal.

Pure gold is soft and is usually alloyed with other metals, such as silver, copper, platinum or palladium, to increase its strength. Gold alloys are used to make jewelry, decorative items, dental fillings and coins. The amount of gold in an alloy is measured with a unit called a karat.

The element gold. Gold is element 79 and its symbol is Au. Though the name is Anglo Saxon, gold originated from the Latin Aurum, or shining dawn, and previously from the Greek.

Identify the geologic principles you would use to determine the relative order of the layers.

kykrilka [37]

Law of superposition

Principle of cross-cutting

Explanation:

The geologic precepts that would be used to determine the relative ages of the rock strata are the law of superposition of strata and the principle of cross-cutting.

The law of superposition of strata states that "in an undisturbed sequence of rock strata, the oldest layer is usually at the bottom and the youngest on top".
From this law we understand that the oldest layer will be at the bottom if the rock has not been disturbed.
Here the rock has been disturbed by folding and we need to unravel to fold and see how the rock sequence originally was laid.

The principle of cross-cutting states that "faults are younger than the rocks they cut through". Structures in rocks are younger than rock layers they cut through.

A fault or joint will only pass through a rock that has been formed before it occurred. Subsequent rocks will be younger than the fault.

Which statment best describes the chamces that occured in the reactant in forming the alkene product

Ganezh [65]

Hello. You did not enter answer options. The options are:

a. The OH group was removed from the reactante

b. The OH group was replaced by an H atom.

c. Two atoms were removed from the reactant.

d. An H atom abd a OH group have been removed drom the reactant.

In addition, you forgot to add an image that complements the question. The image is attached below.

Answer:

d. An H atom abd a OH group have been removed drom the reactant

Explanation:

As you can see in the image, the reagent is an alcohol molecule. For the transformation of the alcohol molecule into an alkene molecule, it is necessary that an intramolecular dehydration occurs, that is, it is necessary that a water molecule (two H atoms and an O atom) go out from inside the alcohol and that is exactly what happened, that is, we can say that an H atom and an OH group were removed from the reagent to form the alkene.
