Answer:

The traditional measure of SURFACE tension of liquids is the du Noüy ring method, (1925, Pierre Lecomte du Noüy) which is a mechanical process, using a measured force to lift a platinum ring from the surface of a LIQUID. The force required is the basis for MEASUREMENT of surface tension of the liquid.

Answer:

Effect of temperature: Since the forward REACTION is exothermic, the increase in temperature favors the backward reaction i.e., the DISSOCIATION of ammonia. That means ACCORDING to le Chatelier's principle, the SYNTHESIS of ammonia is favored at lower temperatures.

Explanation:

Le Chatelier's principle is an observation about chemical equilibria of reactions. It states that changes in the temperature, pressure, volume, or concentration of a system will result in predictable and opposing changes in the system in ORDER to achieve a new equilibrium state.

1. Acid are Sour in taste.

2. Acid are SOLUBLE in Water.

3. All acidic solution conduct electricity.

4. Acid TURNS Blue litmus to red.

5. Acids are corrosive in nature they can destroy paper cloth metal EXACTLY. Thus acid stored in glass containers instead of metal containers.

6. Most of the acids REACTS with metal to form hydrogen gas and respective salt. for example :

7. Most of the acids react with metal carbonate to form respective SALTS, water and carbon dioxide for example :

8. Acid react with base to form respective salts and water.

↴

We know that the taste of curd, lemon juice, Orange juice and vinegar is sour. These substances taste sour because they contain acid in it. The word acid comes from the Latin word acidus which means sour.

Answer:

The LONDON dispersion force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the electrons in two ADJACENT ATOMS OCCUPY positions that make the atoms form temporary dipoles. This force is sometimes CALLED an induced dipole-induced dipole attraction.

Answer:

The lead sulphate is insoluble in dilute sulphuric acid and so you end up with lead CARBONATE COATED in a LAYER of lead sulphate, which stops the acid from getting at the carbonate and so stops the REACTION.

Answer:

ONE of the NITROGEN ATOMS of the UREA is transferred from an amino ACID, aspartate. The other nitrogen atom is derived directly from free NH4+, and the carbon atom comes from HCO3- (derived by hydration of CO2; see Section 9.2).

Explanation:

Answer:

Metallic BOND, force that holds atoms together in a metallic substance. ... The atoms that the electrons leave behind become positive IONS, and the interaction between such ions and VALENCE electrons gives rise to the cohesive or binding force that holds the metallic CRYSTAL together.
