Answer:
a. Second order
b. First order
c. zero order
Explanation:
a. For a second order reaction,
As half life is inversely proportional to initial concentration, therefore, increase in intital concentration will decrease half life of the reaction.
b. First order reaction,
for first order reaction:
y = C + mx
Therefore, plot between ln A and t is a straight line.
c. For a zero order reaction,
Half life is proportional to initial concentration, therefore, increase in initial concentration will increase half life of the reaction.
Triglyceride. Specifically, glucose.
The answer to the first one is C. Strong attraction between ions
The answer to the second one is A. High melting points
Hope this helps :)
Answer:
Explanation:
Ionic bond:
It is the bond which is formed by the transfer of electron from one atom to the atom of another element.
Both bonded atoms have very large electronegativity difference. The atom with large electronegativity value accept the electron from other with smaller value of electronegativity.
For example:
Sodium chloride is ionic compound. The electronegativity of chlorine is 3.16 and for sodium is 0.93. There is large difference is present. That's why electron from sodium is transfer to the chlorine. Sodium becomes positive and chlorine becomes negative ion. Both atoms are bonded together electrostatic attraction occur between anion and cations.
Covalent bond:
It is formed by the sharing of electron pair between bonded atoms.
The atom with larger electronegativity attract the electron pair more towards it self and becomes partial negative while the other atom becomes partial positive.
For example:
In water the electronegativity of oxygen is 3.44 and hydrogen is 2.2. That's why electron pair attracted more towards oxygen, thus oxygen becomes partial negative and hydrogen becomes partial positive.
