An example of a general formula of an acid is
<span>HCl
This is called as hydrochloric acid or hydrogen chloride.
H represents for the atom of Hydrogen
and Cl represents for the atom of Chlorine
Since their charges are -1, and +1, it's ratio is 1:1</span>
Answer:
/......................................................
Explanation:
The correct answer is 2.53 g of precipitate, BaCrO4.
Reactivity trends of halogen:
1) Melting point and boiling points increased down the
group
2) Colour becomes darker.
E.g. Fluorine (pale yellow)
Chlorine (yellowish-green)
Bromine (reddish-brown)
Iodine (purplish-black)
Astatine (black)
3) The reactivity decreases down the group.
Reactivity:
F > Cl > Br > I > At
Answer:
Take 100 ml of a 18 molar solution. The total number of moles is (1 liter/1000 ml) 100 ml 18 moles is 1.8 moles.
1.5 moles in 1 liter so If 1.1 liters of water is added, the total volume is 1.2 liters and 1.8 moles are dissolves in it. 1.8 moles/ 1.2 liters is 1.5 moles per liter.
