Answer:
A
Explanation:
because It's the process by which atmospheric nitrogen is converted either by a natural or an industrial means to form of nitrogen such as ammonia.
Answer:
Ca, Zn, Ni, Al, Fe
Explanation:
The activity series is an arrangement of metals in order of decreasing reactivity.
Metals that are high up in the activity series are very reactive. They displace metals that are lower in the activity series from an aqueous solution of their salts.
The metals; Ca, Zn, Ni, Al, Fe are all above Pb in the activity series hence they will cause Pb2+ ions to come out of solution as solid Pb.
Balanced chemical reaction:
C₃H₈(g) + 3H₂O(g) → 3CO(g) + 7H₂(g).
M(C₃H₈) = 44.1 g/mol; molar mass of propane.
M(H₂) = 2 g/mol; molar mass of hydrogen.
From balanced chemical reaction: n(C₃H₈) : n(H₂) = 1 : 7.
7m(C₃H₈) : M(C₃H₈) = m(H₂) : M(H₂).
7·8310 kg : 44.1 g/mol = m(H₂) : 2 g/mol.
m(H₂) = 2638.09 kg; mass of hydrogen.
Answer:
Basic
Aqueous
Protonated
Reconstitute
Explanation:
Aniline contains the -NH2 group in which the hydrogen atom bears a lone pair of electrons which is capable of accepting a proton hence aniline is basic.
This lone pair makes it possible for aniline to be protonated to yield an ionic substance which enters into the aqueous phase.
Addition of a base leads to the reconstitution of the aniline.
