Answer: Evaporation of salt water
Explanation: During the process of evaporating salt water which involves simple distillation, pure water is separated with salt molecules.
When heated water evaporates from the solution since it is less dense. When condensed it becomes pure water and salt is left out since it is more denser.
Not every plant grows from a seed. Some plants, like ferns and mosses, grow from spores. Other plants use asexual vegetative reproduction and grow new plants from rhizomes or tubers. We can also use techniques like grafting or take cuttings to make new plants.
Answer is: 15,21 liters of nitrogen is needed.
Chemical reaction: N₂ + 3H₂ ⇄ 2NH₃.
V(H₂) = 45,0 L.
V(N₂) = ?
n(H₂) = V(H₂) ÷ Vm.
n(H₂) = 45 L ÷ 22,4 L/mol
n(H₂) = 2,01 mol.
from chemical reaction: n(N₂) : n(H₂) = 1 : 3.
n(N₂) = 0,67 mol.
V(N₂) = 0,67 mol · 22,4 L/mol.
V(N₂) = 15,21 L.

Explanation:
MOLECULAR REACTION EQUATION;
Al(NO3)3(aq) + 3NaOH(aq) --->Al(OH)3(s) +3NaNO3(aq)
complete ionic equation:
Al^3+(aq) + 3NO3^-(aq) + 3Na^+(aq) + 3OH^-(aq) ---->Al(OH)3(s) + 3Na^+(aq) + 3NO3^-(aq)
Net ionic reaction equation;
Al^3+(aq) + 3OH^-(aq) ------> Al(OH)3(s)
None Do. These are all skeleton equations that must first be balances by adding coeffecients.
Also, CuSO4 + Zn -> ZnCl2 + Cu has different products in terms of elements than its reactants...
