Its C. It has to be equivalent to the number divided or multiplied by 5.
Answer:
a. 0.8125 moles of sucrose
b. 277.8 g of sucrose
Explanation:
Consider these relation's value:
Molarity = Mol / Volume(L)
Mol = Molarity . Volume(L)
Volume(L) = Mol / Molarity
So, Molarity = 3.25M
Volume(L) = 0.25L
Molarity . Volume(L) = Mol → 3.25mol/L . 0.25L = 0.8125 mol
Let's convert the moles to mass → 0.8125 mol . 342 g /1mol = 277.8 g of sucrose
Heat transfer is the phenomenon that occurs when the two objects are in the vicinity of each other and by increasing the area of their contact. Thus, option B is correct.
<h3>What is heat transfer?</h3>
Heat transfer is a process that flows the heat from one system to another, and is because of the difference in the temperature of the two objects that are part of the system.
The methods like conduction, convection, and radiation transfer the heat from the surface area to the other object. The heat gets transferred from the area of high to the low temperature.
Therefore, option B. by increasing the surface area the heat transfer increases.

Explanation:
Silver and Gold belong to a special group of metals known as the native metals. They are found naturally on their own and not in combined form in rocks.
- These metals are found uncombined because they are unreactive.
- They prefer to alloy with themselves.
- Calcium and magnesium on the other hand are reactive metals.
- The unreactivity of these metals makes them uncombined in nature.
