Answer:
4.25*10^18
Explanation:
1 mole =6.023*10^23 particles
so 7.07*10^-6 mole=6.023*10^23*7.07*10^-6 particles=4.25*10^18 particles
Filtration can be used to separate mixtures based on the size of their particle.
Filtration is a method to separate different molecule based on size. Filtration mostly used to separate solid substance in a liquid. To separate the molecule, you will need a tools that have smaller holes than the molecule size.
The example of usage of this method would be when you try to remove a substance from homogeneous solution using filter paper. The size of water molecule will be smaller than the paper so the water can pass through. But if the solute size is larger than the paper pore, it will be held and form a residue.
Answer:
1-Fluoro-4-nitrobenzene
Step-by-step explanation:
Step 1. Identify the substituents on the ring,
The groups are <em>fluoro</em> and <em>nitro</em>. They have no priority as functional groups, so the base name is <em>benzene</em>.
Step 2. Identify their relative priorities.
F and NO₂ have no functional group priority, so we list them in alphabetical order. F has <em>alphabetical priority </em>over NO₂. The name becomes <em>fluoronitrobenzene</em>.
Step 3. Number the atoms of the ring.
The C atom bearing the F is <em>C1.</em> Count around the ring, and the NO₂ group is on <em>C4</em>.
Step 4. Name the compound.
Insert the locating numbers <em>immediately in front</em> of the substituents. Use <em>hyphens</em> to join letters to numbers.
The name becomes 1-fluoro-4-nitrobenzene.
If you don’t mind can u add the picture?? It helps me answer the question better ;)
Eventually the oceanic plate is subducted under the continental plate due to the high density of the oceanic plate.
Both — rate :) hope this helps
