Explanation:
It is known that for high concentration of
, reduction will take place. As, cathode has a positive charge and it will be placed on left hand side.
Now,
= 0 and the general reaction equation is as follows.

3.00 M n = 2 30 mM
E = 
= 
= 0.038 V
Therefore, we can conclude that voltage shown by the voltmeter is 0.038 V.
Answer:
Here are a few more examples:
Smoke and fog (Smog)
Dirt and water (Mud)
Sand, water and gravel (Cement)
Water and salt (Sea water)
Potassium nitrate, sulfur, and carbon (Gunpowder)
Oxygen and water (Sea foam)
Petroleum, hydrocarbons, and fuel additives (Gasoline)
Heterogeneous mixtures possess different properties and compositions in various parts i.e. the properties are not uniform throughout the mixture.
Examples of Heterogeneous mixtures – air, oil, and water, etc.
Examples of Homogeneous mixtures – alloys, salt, and water, alcohol in water, etc.
Explanation:
Hello young fellow friend I think the anwser is (C)
Answer:
If one astronaut used more force, then that one would be faster than the other. The independent variable is force. The dependent variable is speed.
Explanation:
Force is what is to be changed. Speed is what is being measured.
IV = Changed/factor DV=Measured/Changes by factor
D is the answer I believe.
