Answer:
C. Cs < K < P
Explanation:
Electronegativity is the basically the tendency of an atom to attract electrons. The pauling scale is used to quantify electronegativity, the most electronegative element; fluorine has a value of 4.0 and francium, the least electronegative element has a value of 0.7
The electronegative values of the following elements are given as;
K = 0.82
Cs =0.79
P = 2.19
Arranging in order of increasing electronegativity, we have;
Cs < K < P. The correct option is;
C. Cs < K < P
Answer:
In models describing the structure of the plant cell wall, the polysaccharide cellulose,which only contains glucose,forms cable-like structures which are associated with interspersed hemicellulose polysaccharides which consist of glucose chains with xylose side groups. The pectin polysaccharides, containing ironic acids, have a more kinked ribbon-like structure and serve to link the cellulose polysaccharides together by providing a gel-like matrix,completing the cell wall structure.
Explanation:
Enthalpy is the change in energy. A cold pack will react endothermically and enthalpy will be positive and a heat pack will have negative enthalpy. You cannot determine which has more change in enthalpy unless you measure the temperature change. Eg. a heat pack went from 25c to 35c will have greater change in enthalpy then a cold pack going from 25 to 20c because the net temperature difference is greater
