i want to know if i id it right . i got BaSo4+2NaCl. and i havent actua;;y learned it yet its for a prelab.
TO balance a chemical reaction though it takes practice, but the first thing you need to do is to identify and make a chart like this: |dw:1443632818209:dw| identify each atom type in the reactants and write them down do the same thing for the products. after you do that write the number of atoms for each type in the reactants and products. when you do that if the number of atoms of each element on the reactants and products do not equal each other your equation is not balanced could you do that and then tell me what you get?
so 2NaCl 2S Ba O4
i meant 2SO4
so yeah if you do this method it's an easy way to see whether your reaction isn't balanced or not almost so yeah you're right we need to put a 2 in front of NaCl to give us 2 atoms of Na and 2 atoms of Cl but you missed one thing. |dw:1443633584339:dw| after we do this we need to look at the whole reaction
oh ok i saw my mistake. and no because they have the same amount right?
now checking your answer is easy
you can go back to the chart you made and see if all the atoms are the same amount so if you like you can copy your previous drawing and tell me what the final answer is?
i got 2NaCl2BaSo4
excellent, I suggest using that method for one reason. you'll be able to easily see whether the reaction isn't balanced or not. but make sure you list al of the reactants and products in the chart.
Ok thank u so much for your help because i haven't actually learned it yet so this is a headstart.Thanks again
thank u =)
@Photon336 i need help with one more thing for this stoichiometry lab. lol and im promise im done.So i did a lab today and i have to find the theoretical yield of copper i know how to find the theoretical yield im just a little confused here is are my results for the lab Mass of Mg used: 0.301 Moles of Mg used:1.248 *10^-2 Mass of Copper produced:.118 grams Moles of Copper produced:1.85 *10^-3 Mg/copper mole ratio: 7:1 Correct equation: Mg(s)+CuSO4---> MgSO4 +Cu all I am missing is the theoretical, actual and percent yeild. I need some guidance Please =)
mass of copper produced is .118g btw
