Answer:
Molecules that have the same chemical formula (same numbers of each atom) but different three-dimensional shapes are called <u>Stereoisomers</u>.
Explanation:
Stereoisomerism is a phenomenon in which molecules have same molecular formula but have different arrangement of atoms or group of atoms in space. It is further classified as;
i) Geometrical Isomerism:
In this class of isomerism the groups or atoms about the double bond occupies different region in space. It is also called as <em>cis-trans </em>isomerism.
ii) Optical Isomerism:
In this class the molecules having same molecular formula differ in their interaction towards plane polarized light.
Answer:
Tile 52 and three are incorrect
Explanation:
Answer:
a. 1.23 V
b. No maximum
Explanation:
Required:
a. Is there a minimum standard reduction potential that the half-reaction used at the cathode of this cell can have?
b. Is there a maximum standard reduction potential that the half-reaction used at the cathode of this cell can have?
The standard cell potential (E°cell) is the difference between the standard reduction potential of the cathode and the standard reduction potential of the anode.
E°cell = E°red, cat - E°red, an
If E°cell must be at least 1.10 V (E°cell > 1.10 V),
E°red, cat - E°red, an > 1.10 V
E°red, cat - 0.13V > 1.10 V
E°red, cat > 1.23 V
The minimum standard reduction potential is 1.23 V while there is no maximum standard reduction potential.
Electromagnets can be created by wrapping a wire around an iron nail and running current through the wire.
