18. A reducing sugar is any sugar that is capable of acting as a reducing agent because it has a free aldehyde group or a free ketone group. All Monosccharides are reducing sugar s, along with some disccharides, oligosccharides, and polysaccharides.
19. b) anomalous behavior of nitrogen is known to differ from other members of the family of the following facts, 1) its small size 2) its high electronegativity 3) its high ionization energy .....
19.or, b) 1. ammonia gas NH3(g)
2. ammonia gas has a characteristic pungent smell.
20. a) any of the metallic elements of groups 3 through 12 in the periodic table that have an incomplete inner electron shell and that serves as transitional link between the most and the least electro positive in a series of elements. they are characterized by multiple valences, colored compounds, and the ability to form stable complexion. also called transition elements.
b) the lanthide contraction is greater than expected decrease in ionic radii of the elements in the lanthenide series from atomic number 57, lathanum , to 71, lutetium which results in smaller than otherwise expected ionic radii for the subsequent elements starting with 72 hafnium.
