Think of a microscope. Microscopic items/beings can only be seen under a microscope. You can also see that they would be very small, because micro = small.
Number of moles:
1.0 mole CH4 -------------- 22.4 L
moles ------------- 30 L
moles CH4 = 30 * 1 / 22.4 = 1.339 moles
Therefore:
1.0 mole CH4 --------------- 6.02x10²³ molecules
1.339 moles ---------------- molecules CH4
molecules CH4 = ( 1.339 ) * ( 6.02x10²³ ) / 1.0
=> 8.6x10²³ molecules CH4
The answer to this question is choice number 3. The answer is AlCl3 and Ag
Answer: Bromide is many orders of magnitude better than fluoride in leaving group ability
Explanation:
As Size of an atom Increases, the Basicity Decreases this is because if we move downwards from the top of the periodic table to the bottom of the periodic table, the size of an atom increases. As size increases, basicity will decrease, meaning the element will be less likely to act as a base implying that the element will be less likely to share its electrons.
in the same vein. With an increase in size, basicity decreases, making the ability of the leaving group to leave increase to increase . This can be seen in the halogens going down the group from
F--- worst
Cl----fair
Br ----good
I-----excellent
with fluorine having the worst ability to leave than Bromine which is better in terms of the leaving group ability.

Explanation:
The <em>blue whale </em>is the largest animal on Earth. The length of a blue whale is about 25 m, although is is said the largest confirmed measure is 29.9m.
The<em> tiny frogs </em>measure about 10mm.
You can estimate the number of tiny frogs that have the same <em>length</em> as a blue whale dividing the approximate average length of a blue whale by the approximate average length of the tiny frogs.
First convert 25m to mm:
- 25m × 1,000mm/m = 25,000 mm
Now, divide:
Hence, about 2,500 <em>tiny frogs sitting next to each other would measure the same length as a blue whale</em>.
