Human made Resources

(i) Resources which are GIFTS of nature.

(ii) It is of two types-biotic and abiotic, e.g., biotic—plants and animals, abiotic— rocks and metals.

(i) Resources which are CREATED by man.

(ii) These are developed by man using his skill and knowledge by UTILISING natural resources, e.g., machines,

NACL dissociates into Na+ and Cl- , making it’s van’t Hoff’s factor 2 , whereas sugars being non-electrolytes don’t dissociate in a SOLVENT , and that makes their van’t Hoff’s factor 1. Because freezing point depression DEPENDS on the van’t Hoff’s factor of solute (ΔTf=i * Kf * m) , it’s a good idea to use a solute having a high van’t Hoff factor for making a solution with LOW freezing point.

These electrons, which are readily lost by reactive metals like sodium, potassium etc are accepted by hydrogen ions of the acids, REDUCING them to hydrogen gas (H2). 2 H+ + 2e- → H2 HOWEVER, non-metals do not lose electrons readily, because of which they do not DISPLACE hydrogen from acids.

ANSWER:

BLUE with SOAP sol

Red with LEMON juice

Explanation:

This is because soap sol is a base and lemon juice is acid. So color CHANGES from red to blue in basic sol and color changes from blue to red in acidic

ANSWER:

trichorrhexis nodosa

Explanation:

Your Answer

Mercury has a higher surface tension than water. This can be seen when LOOKED at a DROP of water and a drop of Mercury. ... Surface tension is DUE to the different forces EXPERIENCED by molecules in the interior of a liquid and those on the surface.

HI there ,

☆ The lowest melting point is AlCl3

◇ Because its have lowest difference in the electronegativity so, the COMPOUND cosidered as covalent

● Al electronegativity value is 1.61

● Cl electronegativity value is 3.16

☆ So the difference = 3.16-1.61= 1.56

◇ Polar covalent compound when difference is from 0.5 to 1.9

◇ Ionic compound when difference is more than 1.9

♡ Hope the ANSWER is helpful

Answer:

In a REACTIVITY series, the most reactive element is placed at the top and the least reactive element at the bottom. More reactive metals have a GREATER tendency to LOSE ELECTRONS and form POSITIVE ions .

Explanation:

Answer:

12.57 g of KCl

Explanation:

MOLALITY = weight of KCl × 1000

/ molar mass of KCl × 75 g

H2O

= X × 1000/74.5×75 = 2.25

so, X = 12.57

Explanation:

if we WANT to CONVERT degree to Kelvin scale we have add that degree to the 273c.

so,now ,1st one is :25c .273+25=298. + 273 +. -127=+146 273+27=300.

Answer:

Differences:-

1) In acid radical the radical has been CONSTITUTED by acid. 2)The ion formed after removal of hydrogen ion from an acid is CALLED acid radical. 1) In basic radical the radical has been constituted by Basic. 2) the ion formed after removal of Hydroxide IONS formic acid is called basic radical.

the RIGHT ANSWER is a AMMONIA is NH3

Answer:

As per the old adsorption theory of CATALYSIS, the reactants in their GASEOUS state or in their dissolved state in any solution get adsorbed on the surface of a SUITABLE catalyst in its solid state. As a result of the increase in the concentration of the reactants on the surface of the catalyst, availability, and probability of the occurrence of a reaction between two species increases, and thus the rate of the reaction increases. Also, as the reactants adhere to the surface of the catalyst some amount of energy is released as the process is exothermic in nature. This heat of combination is utilized in the reaction between the two species, thus enhancing the rate of the reaction.

As per the intermediate compound theory of catalysis, the reaction that is desired is achieved with the FORMATION of an intermediate compound and the following decomposition of the same into the desired products. In this process, the catalyst is regenerated after the reaction is over.

Now, as per the modern adsorption theory, which is a combination of the old theory of adsorption and the intermediate theory of compound formation, the process of heterogeneous catalysis takes place with these five steps,

The reactants diffuse to the surface of the catalysts. In this process, the reactants FIRST get in contact with the external surface, out of which some of them cross the barrier and enter the interior exposed surface that includes paths and cracks on the external surface.

These molecules then get adhered to the suitable sites available for adsorption.

The reactants, when bound to the surface have a higher probability of reacting with each other, and after the reaction, they form an intermediate compound.

After this process, the intermediate compound gets desorbed from the surface, which again becomes available for adsorption for other molecules to come.

The intermediate compound then disintegrates to form the final products, which then diffuse out of the internal pores and the external surface of the catalyst.
