Usually with roman numerals, like iron (II) chromate
iron has a charge of 2
or manganese (IV) oxide, manganese has a charge of 4
(these are ionic compounds just to let you know)
I can't art but I envision a comic of a swimming pool with chlorine water in it. The bottom of the pool is black. The chlorine is happy and excited to protect the people going to swim in it. Then the sun comes out, warms the black tile, the water is heated and the chlorine is boiled into gas form. Unable to control its movement through the atmosphere, the large amount of chlorine from the in-ground pool infiltrates the home of its lovely owners, and they die from chlorine gas inhalation, as well as half the neighborhood.
The end.
Answer:
Percentage yield =58.7 %
Explanation:
moles of calcium carbonate as a reactant =
as per molar equation , 0.2068 moles of calcium carbonate produces 0.2068 moles of CaO .
amount of CaO = 0.2068 mole x (40.078+15.999) g/moles = 11.598 gram
percentage yield = actual yield / theoritical yield = 6.81/ 11.598 = 0.587 or 58.7 %
Ionic bonds are formed due to tendency of a metal to donate an electron and tendency of non metal to gain an electron.
Argon is the noble gas for titanium
