Recycling Isn’t Always Cost Effective.
High Up Front Cost
Needs More Global Buy-In.
Recycled Products Are Often of Lesser Quality.
Recycling Sites Are Commonly Unsafe.
Answer:
c) Fullerene and carbon nanotubes because they have empty spaces inside the molecules
Explanation:
Fullerene and carbon nanotubes would be the most desired in order to hold the cancer fighting drugs and to carry them through the body safely.
- These molecules have empty spaces in them.
- The cavities makes it possible for storage.
- As they pass through the body, they can be held perfectly well to their target site of action.
Hydrated salts are when salt crystals have water molecules bound. Anhydrous salts are when the water has been removed.
mass of water removed = hydrated salt - anhydrate salt
= 11.75 g - 9.25 g = 2.50 g
number of water moles = 2.50 g / 18 g/mol = 0.139 mol
number of cobalt (II) chloride moles = 9.25 g / 130 g/mol = 0.0712 mol
ratio of water moles to CoCl₂ moles - 0.139 mol / 0.0712 mol = 1.95
rounded off 2 moles of water for every 1 mol of CoCl₂
formula - CoCl₂.2H₂O
name - Cobalt(II) chloride dihydrate
Answer:
Fluorine
Explanation:
It is a non-metal does not conduct electricity
Answer:
0.125 mg
Explanation:
<em>The correct answer would be 0.125 mg</em>
<u>According to the conversion factor, one milligram of a sample is equivalent to one thousand micrograms of the same sample.</u>
milligram = 
microgram = 
Hence,
1 milligram = 1000 micrograms or 1 microgram = milligram
Therefore, 125 micrograms will be:
125/1000 = 0.125 milligram
