The correct answer is A) They all have similar chemical properties.

Explanation:

In chemistry, the periodic table organizes visually the chemical elements. In this, elements are arranged according to different features. In the case of families of the elements, these refer to elements organized in the same column, for example, elements that are in column 18 form a family called noble gases.

These elements form a family because they have chemical properties; in the case of noble gases, this includes similar reactivity and physical features such as color and odor. Besides this, the elements of one family share a similar electron configuration but not the same number of electrons. This means, from the options given the one that identifies the elements that belong to a family is "They all have similar chemical properties".

Diamonds are composed of __________ in a ___________lattice. A. silicon, trigonal planar B. quartz, octahedral lattice C. carbon
Nata [24]

Diamonds are composed of carbon in a tetrahedral lattice. That is option C.

<h3>What is a diamond?</h3>

A diamond of defined as an allotrope or one of the major forms of the element, carbon in nature.

These carbon atoms are arranged within the diamond in a face centered cubic tetrahedral lattice shape.

Therefore, Diamonds are composed of carbon in a tetrahedral lattice.

When the pH decreases from 6 to 3, the hydrogen ion, H+, increases by what?
Irina-Kira [14]

pH decreases as the hydrogen ion concentration increases.

<u>Explanation:</u>

When there is a decrease in pH, that is pH decreases from 6 to 3 then the acidity increases.

That is the pH is between 1 to 7 then it is acidic

When the pH is 7 then it is neutral

When the pH is between  7 to 14 then it is basic

As the H⁺ ion concentration increases, then the pH value decreases, here pH decreases from 6 to 3.

So the concentration of Hydrogen ion increases, pH decreases.

4HCI + O2 =2H20 + Cl2
Sergio039 [100]

The rate of the backward reaction increases

Explanation:

It is evident that if the reaction is left to proceed spontaneously, the forward reaction is favored because it results in a decrease in pressure in the system (The total reactants have 5 moles and the products have 3 in total).

Increasing H₂O concentration is then reaction, therefore, stymies the forward reaction and favors the reserves reaction. This is because the reverse reaction will lead to reduced pressure.

Carbohydrate loading Group of answer choices involves a reduction in the intensity of workouts with a corresponding increase in
SOVA2 [1]

Answer:

the correct option would be:

The group of response options implies a reduction in the intensity of the workouts with a corresponding increase in the percentage of carbohydrate intake for several days before a competition.

Since the carbohydrate load is an increase in glycogen reserves as an energy source accompanied by a decrease in muscle demand. This is often used in high-performance activities, where strict competencies are required.

Although today some professionals do not support that, but rather support a diet with carbohydrates and proteins.

Explanation:

Carbohydrate loading increases glycogen reserves, it is accompanied by a muscle rest plan, without fatigue of muscle fibers.

The purpose of this is to exhaust the muscle fibers in maximum demands such as the competencies, ensuring a necessary energy source that supplies this reaction, for which glycogen reserves are needed.
