Answer:
(d) 3,7-dimethyl-4-nonyne.
Explanation:
Hello,
In this case, considering the attached picture on which you can see that the main chain has nine carbon atoms, one tripe bond at the fourth carbon and two methyl radicals at the third and seventh carbons respectively, by following the IUPAC rules, the name would be: (d) 3,7-dimethyl-4-nonyne since the chain must start at the side closest to the first triple bond due to its priority and subsequently considering the present radicals.
Best regards.
Answer:
The mass of Mg consumed is 21.42g
Explanation:
The reaction is
As per balanced equation, three moles of Mg will react with one mole of nitrogen to give one mole of magnesium nitride.
as given that mass of nitrogen reacted = 8.33g
So moles of nitrogen reacted =
moles of Mg required = 3 X moles of nitrogen taken = 3X0.2975 = 0.8925mol
Mass of Mg required = moles X molar mass = 0.8925 X 24 = 21.42 g
Answer:
Al (s) + AgClO3 (aq) will result in a chemical reaction.
Al(s) + 3AgClO₃(aq) -----> Al(ClO₃)₃(aq) + 3Ag(s)
Cd(s) + CuNO3(aq) will also result in a chemical reaction.
Cd(s) + 2CuNO₃ -----> Cd(NO₃)₂ + 2Cu
Explanation:
For chemical reactions, metals lower on the activity series cannot normally displace ions of metals higher than them in the activity series.
Metals at the lower end of the activity series are not easily oxidized.
The activity series is attached to this solution. (Note: Cadmium is not on the attached chart, but Cadmium is between Iron (Fe) & Cobalt (Co) on the activity series)
- Pb is way lower Mg in the activity series, hence, it cannot become oxidized by displacing Mg2+ ion in solution.
- Al is way higher than Ag in the activity series. Hence it will easily be oxidized and displace displace Ag from it's solution easily.
- Cadmium will displace Copper in solution too because Cd is higher than Cu on the activity series.
- Platinum cannot displace Cobalt from solution as Pt is lower than Co on the activity series.
