I'm pretty sure it's A because its just sand and everything else is mixed with something Hope that helped Have a good day! :-)
Answer:hmm i think its C or A!
Explanation:
Answer:
Electrophilic aromatic substitution is the reaction in which the bromobenzene is present with the presence of the nitronium ions and results in the formation of para-bromonitrobenzene.
Explanation:
Bromobenzene in the presence of nitronium ions preferntially forms para-bromonitrobenzene rather than meta or the ortho product.
so. here the reaction been mentioned refers to Electrophilic aromatic substitution.
Electrophilic aromatic substitution: An organic reaction is referred as the aromatic substitution.
In this type of organic reaction a system is present which is an organic system to which an atom gets attached which get replaced by an electrophile.
It is one of the most important reactions of the field synthetic organic chemistry.
the usage of these reactions are in synthesis of the most important intermediates which are used as the precursors in agrochemical, industrial and pharmaceutical products.
Answer:
18.45 g of C
Explanation:
This is a problem of rules of three:
1 mol of C₃H₈ contains 3 moles of C and 8 moles of H
If 8 moles of H are contained in 1 mol of propane
4.10 moles of H are contained in (4.1 . 1) /8 = 0.5125 moles
Now, If 1 mol of propane contains 3 moles of C
0.5125 moles of propane may contain (0.5125 . 3) / 1 = 1.5375 moles of C
Let's convert the moles to mass:
1.5375 mol . 12 g /mol = 18.45 g
Answer:
40 meters
Explanation:
there are 3.29 feet in a meter so 92 feet is 28 meters, also to get meters from millimeters you divide the 3060 by 1000 so 3060/1000=3.06 meters.
