CHEM;
Soap dont foam in hard water because it forms sucm,this is because in acidic water l.e hard water it reacts with excess hydrogen ion to form unionized fatty acid which reduce its cleaning effect.Detergent on the other hand do not form scum in hard water,they retain their cleaning effect irrespective of the water used.

hmmmm...so...can I win you over?

alright have this for breakfast: What volume of gas is liberated when 20g of calcium trioxocarbonate (iv) is treated with excess dilute hydrochloric acid? [Ca=40, C=12, O=16, H=1, Cl=35.5, Molar volume of a gas at s.t.p=22400cm3].
The way you answered my previous question made me wonder if you're just a secondary school graduate. Keep it up!

which element is associated with catenation?

Sorry bro...On the basis of oxidation, describe a simple qualitative test to distinguish between aldehydes and ketones

It helps plants to trap sunlight and it gives plant magnesium. 2. carbon.

Aldehydes which are alkanal are readily oxides to primary alkanol while ketone which are alkanones doesnt oxidize this bring a distint differences.

macduffrx:

Aldehydes do not oxidise to primary alcohol but carboxylic acid. Also, if you say ketones do not oxidise you are not completely correct. The truth is qualitatively, Fehling's solution and Tollen's reagent are mild oxidising agents which only oxidise aldehydes and not ketones. But with stronger oxidising agents like hot concentrated trioxonitrate(v) acid, ketones undergo oxidation and in the process the molecular structure is broken into two

Functions of Chlorophyll.

1. Absorbs light necessary for photosynthesis..
2. Gives plants their characteristic green colour

Carbon atom undergoes catenation.

Bio. 1 Salt, Water, Lysosome. 2. it help to remove dirt and kills germ in the eye due to the presence of lysosome. 3. pupil is located between the cilliary muscle holding the lens, it's the space that light passes through. 4. conjuctiva

Chem. 1. because energy is loss to the environment. 2. Caustic Soda, Washing Soda are used. 3. True solution doesnt scatter ray of light while false solution scatter light ray exempli gratia; starch. 4. Buffer solution is a solution that doesnt change it ph despite it change in concentration.

Google? If I dont know, i wouldnt answer and if i google any ques i wouldnt answer it here again, that's how to learn.

Micropyle is found in the shoot of newly germinating seed while radicle house the root.

Ammonia gas is the most common alkaline gas.Vasectomy is a surgical process that makes a man permanently unable to get a woman pregnant because it involves the cutting of the vas deference which makes it impossible for sperm to get into d semen.
