Vsevolod [243]

Answer:

b. protein

Explanation:

Proteins are biopolymers basically made of carbon, hydrogen, oxygen and nitrogen.

Triglycerides are made of a glycerol molecule esterified by three fatty acids.

Polysaccharides are carbohydrates, and therefore contain carbon, hydrogen, and oxygen.

The mineral salt contains mostly sodium chloride, although it contains some other minerals such as magnesium, potassium, iodine, among others.

The sink-float method is often used to identify the type of glass material found at crime scenes by determining its density.
Olegator [25]

Answer:

<em><u>Glass that will sink</u></em>

  • alkali zinc borosilicate with a density of 2.57 g/mL in a solution with a density of 2.46 g/mL

  • potash soda lead with a density of 3.05 g/mL in a solution with a density of 1.65 g/mL

<em><u>Glass that will float</u></em>

  • soda borosilicate with a density of 2.27 g/mL in a solution with a density of 2.62 g/mL

  • alkali strontium with a density of 2.26 g/mL in a solution with a density of 2.34 g/mL

<em><u>Glass that will not sink or float</u></em>

  • potash borosilicate with a density of 2.16 g/mL in a solution with a density of 2.16 g/mL

Explanation:

Density is the property of matter that states the ratio of the amount of matter, its mass, to the space occupied by it, its volume.

So, the mathematical expression for the density is:

  • density = mass / volume

By comparing the density of a material with the density of a liquid, you will be able to determine whether object will float, sink, or do neither when immersed in the liquid.

The greater the density of an object the more it will try to sink in the liquid.

As you must have experienced many times an inflatable ball (whose density is very low) will float in water, but a stone (whose denisty is greater) will sink in water.

The flotation condition may be summarized by:

  • When the density of the object < density of the liquid, the object will float
  • When the density of the object = density of the liquid: the object will neither float nor sink
  • When the density of the object > density of the liquid: the object will sink.

<em><u>Glass that will sink</u></em>

  • alkali zinc borosilicate with a density of 2.57 g/mL in a solution with a density of 2.46 g/mL, because 2.57 > 2.46.

  • potash soda lead with a density of 3.05 g/mL in a solution with a density of 1.65 g/mL, because 3.05 > 1.65.

<u><em>Glass that will float</em></u>

  • soda borosilicate with a density of 2.27 g/mL in a solution with a density of 2.62 g/mL, because 2.27 < 2.62.

  • alkali strontium with a density of 2.26 g/mL in a solution with a density of 2.34 g/mL, because 2.26 < 2.34.

<em><u>Glass that will not sink or float</u></em>

  • potash borosilicate with a density of 2.16 g/mL in a solution with a density of 2.16 g/mL, because 2.16 = 2.16

Bohr models notes <br> The number of periods shows you the number of _______
lorasvet [3.4K]

Answer:

The number of periods shows you the number of _______

<u>Electron Shell</u>

<u></u>

Explanation:

<u><em>Modern periodic table is divided into Groups and Periods.</em></u>

A period is the horizontal row of the periodic table. There are <u>seven periods </u>in the periodic table.

It describes the following :

  • The period in which a particular element found will show its <u>electron shell</u>
  • The first period has Hydrogen and Helium = 1 - shell
  • The second Period has Lithium to neon = 2- shells

A group is the vertical column of the periodic table . There are <u>18 groups</u> in total.

It describes the following :

The group number of the element is same as the<u> number of electrons in the outermost shell.</u>

The element having group 1 has = 1 electron in outer shell (example Na, K)

The element having group 2 has = 2 electron in outer shell (example Ca, Mg)

The element having group 0 has = full outer shell (example Ne Xe). these are also known as noble gases
