I think this is it
Cd(HCO3)2---->CdCO3+H2O+CO2
Sorry if this is wrong
This is a physical phase change it is still water it just separated and became less and less.it stays water though
this is a dilution question where a certain volume is taken from a more concentrated solution and diluted to make a solution with a lower concentration.
the dilution forumla is as follows
c1v1 = c2v2
where c1 is concentration and v1 is volume of the more concetrated solution
c2 is concentration and v2 is volume of the diluted solution
substituting the values in the equation
18.0 M x V = 0.126 M x 16.5 L
V = 0.1155 L
volume of 115.5 mL is taken from the 18.0 M solution and diluted upto 16.5 L solution.
Answer:
Ionic bonding involves the transfer of electrons from a metal atom to a non-metal atom until the outer shells of their resultant atoms are similar to that of a noble gas. The metals lose electrons and form cations while the non-metals accept the electrons and form anions.
Rigidity is the inability to bent or be force out of shape while compressibility is the ability to be flattened, pressed or squeezed into a smaller piece.
density is the degree of compactness of a substance.
