Physical Properties
Colourless Strong pungent smell Slight alkaline taste Non-poisonous Fatal in large doses Lighter than air - V.D=8.5 Highly soluble in water Easily liquefied at low temp Liquid ammonia boils at -33.5C Solid ammonia melts at -77.7..
Uses of Ammonia
Ammonia solutions are used to clean, bleach, and deodorize; to etch aluminum; to saponify (hydrolyze) oils and fats; and in chemical manufacture. Ammonia is also used in large amounts in the Ostwald process for the synthesis of nitric acid; in the Solvay process for the synthesis of sodium car..
Occurrence of Metals
Metals like gold and platinum occur in the free metallic form not acted upon by air or water The rest of the metals occur in the combined form as compounds. Copper is one of the metals which occur in free as well as combined state Aluminium is the most abundant metal in the earth's crust ..

Gram Atomic Mass
The quantity of an element whose mass in grams is numerically equal to its atomic mass. In simple terms, atomic mass of an element expressed in grams is the gram atomic mass or gram atom. For example, the atomic mass of oxygen = 16 amu Therefore gram atomic mass of oxygen = 16 g The gram atom shou..
Gram Molecular Mass
A quantity of substance whose mass in grams is numerically equal to its molecular mass is called gram molecular mass. In simple terms, molecular mass of a substance expressed in grams is called gram molecular mass. For e.g., the molecular mass of oxygen = 32 amu Therefore, gram molecular mass of o..

I dont even think my school teachers has as much knowledge as this tutors does. Tutor Vista ROCKS.........
Outstanding--the instructor let me do the problem with minimal interruption until I was finished and he helped me identify any errors--wonderful. Thank you tutor vista
