The mixture can be separated into three separate components by using a centrifuge and a separating funnel.
A centrifuge is used to separate a solid that is held in suspension by a liquid. In this case a solid dissolved in water. In contrast, a separating funnel is used to separate two immiscible liquids.
-First take the flask containing the two immiscible liquids and pour contents in to a closed separating funnel.
- The most dense liquid will settle at the bottom, then open the separating funnel valve to collect contents of dense liquid into a flask.
- The remaining liquid on the separating funnel can be collected in a different flask.
-Now take the liquid that is a solution of a solid in water and pour in a test tube. Place the contents in a centrifuge.
- Centrifuge at high speed until the solid sinks to the bottom of the test tube, then decant the liquid into a flask and the solid remains in the test tube
Answer:
B. Molecules of different types of atoms that are not attracted to each other.
Explanation:
On a broad basis, matter can be subdivided into pure or distinct substances and impure substances (mixtures);
Pure substances are distinct substances having the following properties:
- All parts are the same throughout
- Composition is definite
- They cannot easily be separated or broken down into simpler substances by physical means.
- Separation by physical methods is not easy.
- They have a unique set of physical properties.
From this criteria, we see that the second choice is nullified. This is because pure substances have their molecules attracted to each other.
Answer:
The energetic particles coming from the Sun and Saturn's environment allow complex chemistry, such as formation of hydrocarbons and nitriles. The particles also generate a permanent haze around the satellite, rains of methane, winds, seasons Recently, lakes of hydrocarbons seem to have been detected on Titan's surface
Explanation:
Answer:
,
Explanation:
pH is defined as the negative logarithm of the concentration of hydrogen ions.
Thus,
pH = - log [H⁺]
Strong acids dissociate completely and thus, 0.5 M of a solution of a strong acid yields a pH of 1.0 .
The expression of the pH of the calculation of weak acid is:-
Where, C is the concentration = 0.5 M
Given, pH = 4.0
So, for ,
pH = 4.0
<u>Hence, the acid is HOCl.</u>
