Answer:
The potential wrt. calomel is 1.254 V
Explanation:
Given:
Potential wrt. silver chloride
V
Potential wrt. saturated silver chloride
V
Potential wrt. SCE
V
Now potential wrt. hydrogen is given by,
V
And we find for potential wrt. calomel,
potential wrt. hydrogen + potential wrt. SEC

V
Therefore, the potential wrt. calomel is 1.254 V
Ionic bonds form between nonmetals and metals.
The reason ionic bonds are formed is because nonmetals and metals usually have high electronegativities, which essentially means that metals pull on nonmetals' electrons.
When a metal takes an electron from a nonmetal, the metal becomes negatively charged and the nonmetal becomes positively charged. Because opposite charges attract, the two atoms will stick together, thus forming an ionic bond

Answer:
You must add 48.97 mL of water to make the 0.200 M diluted solution.
Explanation:
In chemistry, dilution is the reduction in concentration of a chemical in a solution. In other words, it is the process of reducing the concentration of solute in solution, simply adding more solvent to the solution.
In a dilution, the quantity or mass of the solute is not changed but only that of the solvent. As only solvent is being added, by not increasing the amount of solute the concentration of the solute decreases.
The expression for the dilution calculations is:
Cinitial* Vinitial = Cfinal* Vfinal
In this case:
- Cinitial= 12 M
- Vinitial= 0.830 mL
- Cfinal= 0.200 M
- Vfinal= ?
Replacing:
12 M*0.830 mL= 0.200 M*Vfinal
Solving:

Vfinal= 49.8 mL
Since 0.830 mL is the volume you initially have of HCl, the amount of water you must add is:
49.8 mL - 0.830 mL= 48.97 mL
<u><em>You must add 48.97 mL of water to make the 0.200 M diluted solution.</em></u>
Answer:
A the uneven heating of earths surface
Explanation:
Because earths rotates on its axis, circulating air is deflected torward the right in the northern hemisphere and toward the left Southern Hemisphere. This is called the coriolis effect
