Answer:
See explanation
Explanation:
Anode;
Sn(s) ------> Sn^2+(aq) + 2e
Cathode;
Mn^2+(aq) + 2e ------> Mn(s)
The minimum voltage required to drive the reaction is the cell voltage. The cell voltage is obtained from;
E°cell= E°cathode - E°anode
E°cell= -1.19 - (-0.14)
E°cell= -1.05 V
Answer:
D. Conductor
Explanation:
Conductors are the substances which are good conductors of both heat and electricity. These substances have free electrons present around the nucleus which is the main reason for conduction. Metals like copper, gold, silver, iron and steel etc are the examples of conductor. Gold is best conductor but cannot be used due to high cost. After gold, copper is the best conductor so that's why it is used extensively in electric wires.

Answer:
a. magnesium
b. nitrogen
Explanation:
Barium and magnesium are both in 2nd group, so most similar compounds.
Nitrogen - 15 group, so it forms least similar to barium compound.
<u>The correct answers are </u>
- An atom of oxygen and the ion of oxygen both have 8 protons.
- As you add or remove neutrons from the nucleus, isotopes are formed.
Answer: Options A and D
<u>Explanation:</u>
An isotope of an element is formed by varying their number of neutrons and not on changing the number of electrons or protons. Similarly, an atom can be converted into an ion by adding or removing one or more electrons.
So the number of protons will not be changed for becoming an ion. Thus, the correct answers are that an atom of oxygen and ion of oxygen will be having 8 protons. Similarly, an isotope formation is possible on addition or removal of neutrons from the nucleus. All other options are not true as there will be no change in the number of electrons for isotope formation.
