Answer:
Ion exchange.
Explanation:
One of the ways in which water can be treated is through the process known as ION EXCHANGE. Using this for treating water has to do basically with the transfer or say the exchange of ions.
Ion exchanges is done by exchanging ions which are considered as 'unfit' or contaminants by the ones that are "fit".
Ions from what is known as zeolite or resin is been exchanged with the ions in the water. Cations are exchanged with cations and anions are exchanged with anions.
NB: this method is a good method or removing contaminants that are ions but not contaminants that are not ions.
As a solution is contained with 11% by mass of sodium
chloride, this will therefore conclude that the 100g of the solution is
composed of the 11g of the sodium chloride. In which, the correct answer would
be specified as letter c.
The correct answer is C) A substance changes color when heated, but changes back when cooled. Hope this helps.
Answer:
ionic bonding occurs between ions and covalent bonding occurs when atoms have electrons in common (they share).
Assuming we know nothing else about the properties of lithium when looking at the periodic table we can see Li is a pretty lightweight element. This could be very useful when making batteries
