Davy used the same separation technique to pull apart caustic soda, or lye, and as such this would reveal another new element known as sodium.

<h3>What is a separation technique?</h3>

A separation technique can be defined as a technique that is used to separate (convert) two or more mixture and solution of chemical substances into distinct products such as solutes, chemical compounds or elements.

<h3>What is a chemical element?</h3>

A chemical element can be defined as a pure substance which comprises atoms that have the same atomic number (number of protons) in its nuclei and as such it is the primary constituent of matter.

Generally, some examples of a chemical element include the following:

  • Argon.
  • Sodium.
  • Carbon.
  • Oxygen.
  • Hydrogen.

In Chemistry, sodium hydroxide, caustic soda, or lye all refer to the same chemical compound which is represented by this chemical symbol, NaOH.

According to the narration, Davy used the same separation technique to pull apart caustic soda, or lye, and as such this would reveal another new element known as sodium.

For a reaction:
torisob [31]

Looking at the equation .look at the moles noted below

  • Ca(OH)_2=1mol
  • NH_2Cl=2mol.
  • CaCL_2=1mol
  • NH_2=2mol
  • H_20=2mol.

#a

There is 2 moles of NH2Cl.

  • Hence limiting reagent is Ca(OH)_2

#2

Moles at reactant=3

Moles at product=5

Moles left:-

\\ \sf\longmapsto 5-3=2mol

#d

\\ \sf\longmapsto pV=nRT

\\ \sf\longmapsto 1.5V=2(8.3)(27)

\\ \sf\longmapsto 1.5V=448.2

\\ \sf\longmapsto V=\dfrac{448.2}{1.5}

\\ \sf\longmapsto V=298.8mL

_________ is a systematic method of naming chemical compounds. This creates an unambiguous and consistent name for any chemical
Vlada [557]

Answer: IUPAC NOMENCLATURE

Explanation:

IUPAC stands for International Union of Pure and Applied Chemistry. They devised a systematic method for naming compounds in order to create a uniform global unambiguous system of nomenclature hence making it easier for researchers to share information more freely without the hindrance of reporting the same compound using different names in different parts of the world thus creating confusion in chemical literature.

What are the angles in a 30°−60°−90° triangle after it is rotated clockwise 45°?
mina [271]

Angles do not change they can only rotate in a circular motion if the angles in a 30°−60°−90° triangle after it is rotated clockwise at 45°.

<h3>What are the angles?</h3>

The angles are the distance between two lines that are attached at one point and they can vary in shapes like triangle and square or circle and rectangle.

The square has the handle of equality for all the sides rectangle has two opposite side angles equal and the circle It has only one angle triangle consisting of 3 angles which are fixed and cannot be changed.

Therefore, if the angles in a 30°−60°−90° triangle after it is rotated clockwise at 45°Angles do not change they can only rotate in a circular motion.
