Answer:
a structural formula
Explanation:
A structural formula simply shows the arrangement of atoms on a compound or molecule.
They are mostly used in representing hydrocarbons.
Through a structural formula we can give name to a compound.
For example, the compound given is called Propane, an aliphatic hydrocarbon with 3-carbon atoms.
The bond relationship connecting the species are also shown in this designation.
Answer: b, and e
Explanation:
b) n = 3 , l = 2 , m = 1 , m s = − 1/2
e) n = 5 ,l= 4 , m = − 4 , m s = − 1/2
B. <span>The heat lost by the metal will equal the heat gained by the water</span>
The question is incomplete, the complete question is:
Standard reduction potentials for zinc(II) and copper(II)
The standard reduction potential for a substance indicates how readily that substance gains electrons relative to other substances at standard conditions. The more positive the reduction potential, the more easily the substance gains electrons. Consider the following:
Zn2+(aq)+2e−→Zn(s),Cu2+(aq)+2e−→Cu(s), E∘red=−0.763 V E∘red=+0.337 V
Part B
What is the standard potential, E∘cell, for this galvanic cell? Use the given standard reduction potentials in your calculation as appropriate.
Express your answer to three decimal places and include the appropriate units.
Answer:
1.100 V
Explanation:
E∘cell= E∘cathode - E∘anode
E∘cathode= +0.337 V
E∘anode= −0.763 V
E∘cell= 0.337-(-0.763)
E∘cell= 1.1V
