The pH of distilled water is 7. This is the neutral pH, showing that the ratio of H+ ions and OH- ions is at equilibrium.
Answer:
Group 13
Explanation:
We have been given some properties of the elements we desire to identify.
The most important and by far unique is the oxidation state of the ions given. This reflects the amount of electrons an atom has lost or gained.
Group 1 and 2 elements have oxidation states of +1 and +2 respectively. This is a very perculiar property of these metals. When group 1 elements lose an electron, nobility is achieved and this goes for group 2 elements too.
Group 12 consists of transition elements. Most transition elements are known to have variable oxidation states. In this group, the common oxidation state is +2.
Group 13 elements have two dominant oxidation numbers which are +1 and +3. Particularly, Aluminum has +2 oxidation state too.
The properties fits in well for aluminum which is a group 13 element.
Answer:
Moles of zinc chloride produced are 0.09942 moles.
Explanation:
Mass of zinc used = 6.5 g
Moles of zinc =
According to reaction, 1 mol of zinc gives 1 mole of zinc chloride,then 0.09942 moles of zinc will give :
of zinc chloride
Moles of zinc chloride produced are 0.09942 moles.
D. Small geographic range
