blem with acid lakes is that acid lakes consume water hardness as the acid lakes are neutralized by liming. If the water in the acid lakes were not acidic, the water hardness would most likely be good, as it PROBABLY was centuries ago. Calcium and magnesium present in most rock and mineral deposits are dissolved into the water by acidic rain and GROUNDWATER. In this case, acid rain performs a useful function of increasing water hardness. Water hardness is NATURE’s way of removing excess phosphorus from lakes. A common solution to increase water hardness in acid lakes is to add lime, a high-alkalinity calcium compound to the acid lakes. This METHOD is only temporary and very expensive, as it often needs to be APPLIED every year

d unit of MEASUREMENT provides a REFERENCE point by which objects of weight, length or capacity can be DESCRIBED. Although measurement is an important part of everyday life, kids don't automatically understand that there are MANY different ways to measure things. A standard unit of measurement is a quantifiable language that helps everyone understand the association of the object with the measurement.Holding your hand rigid, measure the length of the table in hand spans. How many of your hand spans does it take to cover the length of the table? How many of your child's hand spans? Now, measure the length of the BOOK in hand spans. Your child may notice that the number of hand spans required to measure the table and book is different than the number of hand spans it took for you to measure the objects.

is only soluble in carbon DISULPHIDE. Now, phosphorous is not.So when we dissolve the MIXTURE of SULPHUR and phosphorous in carbon disulphide , the sulphur is dissolved in the carbon disulphide while the phosphorous is LEFT out. Just filter the mixture and you'll get phosphorous.To get sulphur just use the distillation or evaporation technique.

roteins have difference characteristic features as size, shape, net charge, stationary phase used, and binding capacity, each one of these characteristic components can be purified using chromatographic methods. Among these methods, most frequently column chromatography is applied. This technique is used for the purification of biomolecules. On a column (stationary phase) firstly the SAMPLE to be separated, then wash buffer (mobile phase) are applied (Figure 1). Their FLOW through inside column MATERIAL placed on a fiberglass support is ensured. The samples are accumulated at the bottom of the DEVICE in a tme-, and volume-dependent MANNER

dioxide passed into limewater gives a MILKY SOLUTION, due to PRECIPITATION of an insoluble SUSPENSION of calcium carbonate: Ca(OH)2(aq) + CO2(g) → CaCO3(s) + H2O. If excess CO2 is added, the following reactionCaCO3(s) + H2O(l) + CO2(g) → Ca(HCO3)2(aq) takes place: ... Themilkiness disappears since calciumbicarbonate is water-soluble.

Retention REFERS to the process wherein the configuration of the molecule is RETAINED after the reaction.↔ Inversion refers to the process wherein the configuration of the MOLECULES is reversed during the COURSE of the reaction.✔✔ Hope it helps u a lot ❤❤

me has much less tendency to absorb water. The SOLID sodium SALT of a carboxylic acid is mixed with solid soda lime, and the mixture is heated. ... You can think of this as FIRST a REACTION between the acid and the soda lime to make sodium benzoate, and then a decarboxylation as in the first example.

is a polycyclic aromatic hydrocarbon (PAH) CONSISTING of four fused benzene rings, resulting in a FLAT aromatic system. This colourless solid is the smallest peri-fused PAH (one where the rings are fused through more than one face). Pyrene forms during incomplete combustion of organic compounds.Most of the PAHs are used to conduct research. Like most PAHs, pyrene is used to make dyes, plastics and pesticides. It has ALSO been used to make another PAH CALLED benzo(a)pyrene.

rization takes place in such COMPOUNDS who has KETO group or enol group. i.e. they can interchange in to each other to form more stable compound.In 1st OPTION there is bridge head keto group. Its enol is not stable due to formation of πbond at bridge head carbon. So, no tautomerization.In 2nd option, on forming enol compound, there are TWO possibilities.1st is that pibond can be formed through bridge head carbon and 2nd is that pibond is from through carbon attached with 2 phenyl groups. but in 1st case unstable sructure. hence rejected. in 2nd case no αH to form pibond. hence, No tautomerization.similarly in 3rd option no αH from both the sides to form enol compound. hence no tautomerization.     4. but in 4th option, from right hand side there is methyl group attached to the pibonded carbon atom. Hence its resonating structure can be formed . due to which enol compound can be formed.for better understanding see the below attachment
