What is the reaction of silver nitrate and calcium chloride?
Got this from chemtutor.com - better answer BALANCING IONIC EQUATIONS WITH POLYATOMIC IONS Silver nitrate and calcium chloride solutions combined produce a precipitate of silver chloride and leave a solution of calcium nitrate. This time we have ionic compounds in the reaction. Until you are sure of the compounds, you might want to write the ionic materials as the ions, as demonstrated here. _ Ag+(NO3)- + _ Ca2+Cl-2 _ Ag+Cl- + _ Ca2+ (NO3) -2 Notice that from one side to the other there is no change in the nitrate ion. In this case you can count the nitrate ion as a whole rather than splitting it up into nitrogen and oxygen. Your thoughts might go this way: How many silvers on the right? One. How many silvers on the left? One. They are the same. How many nitrates on the left? One. How many nitrates on the left? One. How many nitrates on the right? Two. We need to put a coefficient of two in front of the silver nitrate. 2 AgNO3 + _ CaCl2 _ AgCl + _ Ca (NO3)2 This changes the balance of silvers, so we have to put a two in front of the silver chloride. 2 AgNO3 + _ CaCl2 2 AgCl + _ Ca (NO3)2 Now let's check again. Two silvers on each side. Two nitrates on each side. One calcium on each side and two chlorides on both sides. The balanced reaction is: 2 AgNO3 + CaCl2 2 AgCl + Ca (NO3)2 Hope this will come handy! =] UNBALANCED: AgNO3 + CaCO2 ---> AgCO + Ca(NO3)2 BALANCED: 2AgNO3 + CaCO2 ---> 2AgCO + Ca(NO3)2 >> as a note to the previous editor... that is not calcium chloride in the mix, it is instead calcium carbonate... students take note...<<
What is the chemical fomula for dinitrogen oxide?
The chemical fomula for dinitrogen oxide is N2O.
How many atoms are in 2AL2O3?
The 2 in front means 2 formula units, or 2 moles of the compound Al3O2. So you would multiply the 2 in front times the subscripts in the formula unit Al3O2. In the formula unit Al3O2, there are 5 atoms. Multiply that by the 2 in front and you get 10 atoms.
