Seawater, which covers the majority of the earth, is composed primarily of molecules of H2O and equal numbers of Na ions and Cl-
Vsevolod [243]

Explanation:

Species present are H_{2}O(l), Na^{+}(aq) and Cl^{-}(aq). Now, we will calculate the number of componenets present as follows.

                C = n - E

where,   E = number of independent equations

              n = number of phases present

Therefore, we will calculate the number of components as follows.

                        C = 3 - 1

                            = 2

Since, sodium chloride (NaCl) will tend to form a homogeneous mixture in water. Therefore, phase will be equal to 1.

Therefore, it means that there are two components present in one phase.

Which of the following could lead to static discharge?
Ahat [919]

Answer:

Static charge is caused by the build up of electrons on the atoms of an object.

Explanation:

You can experience this yourself with a balloon! Rub it against your head in order to disassociate electrons from it, causing it to be charged - you can now put it on a wall and notice how it 'sticks' to it. You can also cause this effect by jumping on a trampoline, causing static charge to be built up - which is sometimes why you feel a little 'zap' when you touch the sides of it.
