Answer:
A. Fault blocks
Explanation:
The block mountains are formed by pieces of the crust that breaks down and pieces are pushed up by the movement of the crust around them. These type of mountains usually have a steep and a slope side, due to the irregular nature of the fracture. Example of such mountains are the Sierra Nevada mountains in North-America.
<u>They're not caused by the collision of two tectonic plates</u>, like most of the mountains of our planet.
Answer:
The correct answer -
a. Cd and Pb(NO3)2
b. Redox reactions
c. Pb and Cd(NO3)2
Explanation:
This is the reaction known as the redox or reduction-oxidation reaction of metals. In this particular reaction, there are two reactants Cadmium (III) in solid-state and lead (II) nitrate in the aqueous state. At the end of this reaction, the products that we get are lead (II) in solid-state and Cadmium (III) nitrate in the aqueous state.
cadmium (s)+ lead nitrate (aq) = lead (s) + cadmium nitrate (aq)
Cd (s) + Pb2+(aq) → Pb(s) + Cd2+(aq)
Here, Oxidizing agent is Pb2+ and the reducing agent is Cd.

Answer:
mmoles of potassium ion = 75.264 mmoles
mmoles of dichromate ion = 37.632 mmoles
Explanation:
Considering:-
For :
Molarity = 0.0840 M
Volume = 448 mL
The mmoles of are;-
In 1 mmole of , 2 mmoles of potassium ion and 1 mmole of dichromate ion is present.
In 37.632 mmole of , 2*37.632 mmoles of potassium ion and 1*37.632 mmole of dichromate ion is present.
<u>mmoles of potassium ion = 75.264 mmoles</u>
<u>mmoles of dichromate ion = 37.632 mmoles</u>
