The pressure on 1.1 L of a gas, changes from 1240 mmHg to 800 mmHg, what is the new volume?
Answer:
2
Explanation:
Devising a repellent would by far be the most successful scenerio. The synthetic compound N,N-diethyl-meta-toluamide (DEET) is a good example of this repellant.
Answer:
secondary alcohol
Explanation:
NaOH in solution provides OH- nucleophile.
When 2-chloropropane is treated with NaOH, nucleophillic substitution reaction takes place.Here leaving group is Chlorine atom (Cl).
Here OH- replaces Chlorine (Cl) to form 2-propanol which is a secondary alcohol.(OH group attached to 2° carbon)
Other possibility is elimination reaction in which NaOH acts as base.
NaOH acts as base when it is concentrated and aqueous NaOH acts as nucleophile.
In that case,the product formed will be an alkene.(not there in option)
Hey there!
C₇H₉+ HNO₃ → C₇H₆(NO₂)₃+ H₂O
Our elements: C, H, N, and O.
Balance H.
Ten on the left, eight on the right. Add a coefficient of 2 in front of H₂O.
C₇H₉+ HNO₃ → C₇H₆(NO₂)₃+ 2H₂O
Balance N.
One on the left, three on the right. Add a coefficient of 3 in front of HNO₃.
C₇H₉+ 3HNO₃ → C₇H₆(NO₂)₃+ 2H₂O
This unbalanced H, let's increase the coefficient in front of H₂O from 2 to 3 to rebalance.
C₇H₉+ 3HNO₃ → C₇H₆(NO₂)₃+ 3H₂O
Balance O.
Nine on the left, nine on the right. Already balanced.
Balance C.
Seven on the left, seven on the right. Already balanced.
Our final balanced equation:
C₇H₉+ 3HNO₃ → C₇H₆(NO₂)₃+ 3H₂O
