    During the whitewashing process, lime water (Ca(OH)2 + H2O) is applied on the walls in order to give a smooth finish. When this Lime Water reacts with the carbon dioxide present in the air, a layer of CaCO3 is obtained over the walls. The presence of this milky white compound causes the wall to look lighter after 2 days.

    Adithya Dev A 4 years, 4 months ago

    1) Salivary glands = secrete saliva which has an enzyme called salivary amylase. It concerts 30% of starch present in the food into maltose. 2) Pancreas = secretes pancreatic juice which contains an enzyme known as pancreatic amylase. It converts the remaining 70% starch into maltose. 3) Intestinal Glands = secretes intestinal juice which contains an enzyme called Maltase. It converts the maltose in the food to glucose.

    Bases that are highly soluble in water are called ALKALIS. They are usually STRONG and HIGHLY CORROSIVE in nature as they dissociate completely into OH- (aq) ions when in aqueous solutions when compared to other bases. They are usually formed out of highly reactive metal radicals like Na+, K+, Li+, etc. Eg :- NaOH, KOH, etc.

    characteristics of an image(formed on plane mirror) are: It is virtual It is erect and of the same size as the object The distance of the object from the plane mirror is the same as the distance of the image from the plane mirror. One of the important characteristics of the image is that it is laterally inverted Properties of the image formed by a convex mirror : The image is always virtual and erect. The image is highly diminished or point sized. It is always formed between F and P. Concave mirrors can produce both real and virtual images; they can be upright (if virtual) or inverted (if real); they can be behind the mirror (if virtual) or in front of the mirror (if real); they can also be enlarged, reduced, or the same size as object.

    Substances which allow light to pass through them are known to be TRANSPARENT.

    There always exist a chance that magnesium would react with air even before burning to obtain a layer of magnesium carbonate over the metal. This slows down the pace of the reaction of air with the metal ribbon. To remove this layer, the ribbon should be cleaned.
