Trees are a renewable resource that can be used as an energy source.
Answer:
0.535 g
Explanation:
The reaction that takes place is:
- NaCl + AgNO₃ → AgCl + NaNO₃
First we <u>calculate how many AgNO₃ moles are there in 25.0 mL of a 0.366 M solution</u>, using the <em>definition of molarity</em>:
- Molarity = moles / liters
- moles = Molarity * liters
<em>Converting 25.0 mL to L </em>⇒ 25.0 / 1000 = 0.025 L
- moles = 0.366 M * 0.025 L = 0.00915 mol AgNO₃
Then we <u>convert AgNO₃ moles into NaCl moles</u>:
- 0.00915 mol AgNO₃ *
= 0.00915 mol NaCl
Finally we<u> convert NaCl moles into grams</u>, using its <em>molar mass</em>:
- 0.00915 mol NaCl * 58.44 g/mol = 0.535 g
The convection current in the atmosphere is best explained as the process by which hot air expands and rises, becoming cooler and denser, then falling again in a continuous process.
Heat transfer by convection involves the transfer of heat by the actual movement of the heated molecules from the hot parts to the cooler parts of a fluid.
The continuous movement of hot air or liquid from bottom to the top and cold liquid or air from the top to the bottom is known as convection current.
Thus, we can conclude that convection current in the atmosphere is best explained as the process by which hot air expands and rises, becoming cooler and denser, then falling again in a continuous process.

Answer:
number 1 is b and and number two d
Explanation:
Here, Molar mass of N2O4 = 92.02 g/mol
So, Number of molecules in 1 mole (92.02 g) = 6.023 * 10²³
Number of molecules in 76.3 g = 6.023 * 10²³ / 92.02 * 76.3
= 6.023 * 10²³ / 1.20
= 5 * 10²³
In short, Your Answer would be approx. 5 * 10²³ molecules
Hope this helps!
