Answer:

A. Shivering

Explanation:

This is the job of the excretory system. You remove waste as a gas (carbon dioxide), as a liquid (urine and sweat), and as a solid. Excretion is the process of removing wastes and excess water from the body. Recall that carbon dioxide travels through the blood and is transferred to the lungs where it is exhaled.

Answer:

50.25 g of sulphur, S.

Explanation:

Mass of Na₂SO₄ = 223 g

Mass of sulphur =?

Next we shall determine the molar mass of Na₂SO₄. This can be obtained as follow:

Molar mass of Na₂SO₄ = (23×2) + 32 + (16×4)

= 46 + 32 +64

= 142 g/mol

Mass of S in 142 g of Na₂SO₄ = 32 g

Finally, we shall determine the mass of S in 223 g of Na₂SO₄. This can be obtained as follow:

142 g of Na₂SO₄ contains 32 g of S.

Therefore, 223 g of Na₂SO₄ will contain = (223 × 32) / 142 = 50.25 g of S.

Thus, 223 g of sodium sulfate, Na₂SO₄ contains 50.25 g of sulphur, S.

Answer:

They are placed on the periodic table based on their atomic number.

Explanation:

In the chemistry table, you can find the molecular mass and atomic number. Atomic number represents the number of the protons of an atom, and molecular mass represents the mass of the atom. The mass of an atom is made from proton and neutron. The element is made by arranging it based on the number of protons, which was the atomic number.

Answer:

When we put elements on the periodic table we use the atomic mass

Answer: A dilation with rule: [tex](x,y)\to(\dfrac12x,\dfrac12y)[/tex]

Explanation:

A dilation is a non-rigid transformation that creates an image that is the same shape as the original but has a different size.

It uses a scale factor k such that

[tex](x,y)\to(kx,ky)[/tex]

(x,y)= coordinates of original figure

(kx,ky) = corresponding coordinate in the image.

To transform: A (3,-4) onto point A' (1.5,-2).

Using scale factor k= [tex]\dfrac12[/tex], we have

[tex]A(3,-4)\to A'(\dfrac12\times3, \dfrac12\times-4)=A'(1.5,-2)[/tex]

Required rule: [tex](x,y)\to(\dfrac12x,\dfrac12y)[/tex]

Answer:

1 mole is equal to 1 moles NaOH, or 39.99711 grams.

Explanation:

Hope this helps have a nice day :)

The statement of the mass of sodium hydroxide (NaOH) is "130 g."

A substance is something to do with mass that takes up space. The mass of a compound is the total amount of atoms present in grams that make up a molecule. The grams is the unit of mass.

In order to determine the mass in grams, multiply moles of the substance value by its molar mass to convert moles into grams.

Mole to gram conversion factor,

[tex]=\;given \;mole\;.\;\frac{grams}{1\;mol}[/tex]

Mass of NaOH comes out to be,

[tex]=\;3.25\;mol\;.\;\frac{39.997\;g}{1\;mol}[/tex]

= 129.99 g

= 130 g

Hence the correct answer is 130 g.

Answer:

A sample of helium gas has a volume of 620mL at a temperature of 500 K. If we ... to 100 K while keeping the pressure constant, what will the new volume be?

Explanation:

A sample of helium gas has a volume of 620. Ml at a temp of 500 K. If we decrease the temperature to 100K while keeping the pressure constant 124 ml will the new volume be.

Volume is a measurement of three-dimensional space that is occupied. It is frequently expressed quantitatively using SI-derived units, as well as several imperial or US-standard units. Volume and the notion of length are connected.

The capacity of an object is measured by its volume. For instance, a cup's capacity is stated to be 100 ml if it can hold 100 ml of water in its brim. The quantity of space occupied by a three-dimensional object can also be used to describe volume.

According to Charles' Law, at constant pressure,

V1 / T1 = V2 / T2

V1 = 620 ml and T1 = 500K, V2 = ? , T2 = 100K

620 ml / 500K = V2 / 100K

V2 = ( 620 ml ) ( 100K ) / 500K

Volume = 124 ml

Thus, If we decrease the temperature to 100K while keeping the pressure constant 124 ml will the new volume be.

The dark moths were better hidden from predators and therefore more of them survived and this allowed them to have offspring.

Answer:

The dark moths were better hidden from predators and therefore more of them survived and this allowed them to have offspring.

Explanation:

If all of the light colored trees disappeared and there are only dark colored ones, then that means that the light colored moths wouldn't be able to live long since their traits wouldn't match the environment. This then leads to the conclusion that dark moths would be better hidden since their trait fits their current environment and would let them be hid much better from predators. This would allow them to survive longer and eventually, reproduce.

Answer:

[tex]CCl_{2}[/tex]

Explanation:

When calculating an empirical formula from percentages, assume you have a 100g sample. This allows you to convert the percentages directly to grams, because X % of 100g is X grams.

So:

14.6% C = 14.6g C, 85.4%Cl = 85.4g Cl

The next step is to divide each mass by their molar mass to convert your grams to moles.

14.6g/12.01 = 1.22 mol

85.4g/35.45= 2.41 mol

Then you will divide all of your mol values by the SMALLEST number of moles. This gives you whole numbers that are the mole ratio (subscripts) of the empirical formula.

1.22 mol/1.22 mol = 1

2.41 mol/1.22 mol = 2

So the empirical formula is

[tex]CCl_{2}[/tex]

The empirical formula of the compound is CCl2.

HOW IS EMPIRICAL FORMULA CALCULATED:

C = 14.6g ÷ 12g/mol = 1.22mol

Cl = 85.4g ÷ 35.5g/mol = 2.41mol

C = 1.22mol ÷ 1.22 = 1

Cl = 2.41mol ÷ 1.22 = 1.97

Approximately, the carbon to chlorine ratio is 1:2, hence, the empirical formula of the compound is CCl2.
