1 answer:

7 0

The classification of each of the elements into nonessential element, essential bulk element, or essential trace element are as follows:

Nonessential elements:

Alumimium,
Argon,
Helium

Essential bulk elements:

Carbon,
Nitrogen,
Calcium,
Hydrogen

Essential trace elements:

Iron,
Copper.

The complete question

The elements are: Hydrogen, iron, Copper, Nitrogen, Helium, Carbon, Aluminum, Calcium, Argon

<h3>What is Essential and Nonessential Elements?</h3>

Nonessential elements as the name implies are elements which are not necessary for the functional routine of the body and hence are not included in diets.

Essential bulk elements are elements which are needed for the proper functioning of the body and hence are required in relatively large amounts.

Essential trace elements are required in minute quantities in the body.

If there are 12 x 1023 oxygens in a sample of water, how many grams of hydrogen are in the sample?.

AveGali [126]

The amount of grams of hydrogen that are in the water sample is;

3.985 g

<h3>Avogadro's number</h3>

We are given that;

Number of moles of oxygen in a sample of water = 12 × 10²³

Now, the chemical formula of a molecule of water is H₂O. This means that for every 1 atom or molecule of oxygen, there must be 2 hydrogen atoms or molecules present.

Since Number of moles of oxygen in the sample is 12 × 10²³, then number of moles of hydrogen will be twice that = 2 × 12 × 10²³ = 24 × 10²³ moles

Now, molar mass of hydrogen is 1 g/mol and we know that;

Molar mass = Avogadro's number(6.023 × 10²³) moles

Thus;

6.023 × 10²³ moles = 1 g/mol

Thus; 24 × 10²³ moles of hydrogen = ( 24 × 10²³ × 1)/(6.023 × 10²³)

⇒ 3.985 g

Which represents the solution set to the inequality ? x –1 x x is greater than or equal to StartFraction 7 Over 16 EndFraction.

Vikentia [17]

Inequalities are used to represent unequal expressions.

The solution set to $\mathbf{x \ge \frac{7}{16}}$ is: $[\mathbf{\frac{7}{16}, \infty)}$

The inequality is given as:

$\mathbf{x \ge \frac{7}{16}}$

From the inequality above, we have the following observation.

The value of variable x starts from 7/16 (inclusive)
The value of variable x has no end (i.e. infinity)

Because, 7/16 is inclusive of the values of x, we make use of the open square bracket i.e. [

We treat $\infty$ , as an exclusive value. So, we make use of the close parenthesis i.e. )

Hence, the solution set is: $[\mathbf{\frac{7}{16}, \infty)}$
