Start your seeds off indoors - they need plenty of warmth to germinate.
Fill a seed tray or some 10cm pots with moist seed compost and flatten down.
Sow a few seeds on top and cover with a fine sprinkling of vermiculite or compost.
Place in a propagator at a temperature of 18-25C (64-77F).
Answer:
Cations, Oxygen, Anions, Hydrogen
Explanation:
Water molecule is polar (meaning it has dipoles). The oxygen having a higher atomic mass attracts most of the electron cloud of the molecule becoming partially negatively charged and leaving the hydrogen end to be partially positive.
An Ionic compound is one between two atoms where one donates its electrons to the other for both to achieve stable configuration. The two atoms, therefore, become charged and are bought together by electrostatic forces.
When an ionic compound is put in water, it dissociates into its ions (anions and cations) They attract and repel with the polar water molecules depending on their charges. The anions (negatively charged ion) are surrounded by water molecules with the hydrogen ends and the cations are surrounded by water molecules with the oxygen ends.
An exponential growth graph looks pretty much like the right side of a parabola. The graph equation is f(x)= C ·a^x, so you can also plug in x values to find the y value. It's not a linear line, but it curves upwards starting from (0,0).
