Pb(NO3)2 + KI - - > KNO3 + Pb1, *** This equation is not balanced
If 9.12 mole of Kl are used in this reaction, how many moles of Pb(NO3)2 are required for the reaction? ​

i had this on my unit activity, i can you if you are a plato student. are you a plato student?

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the volume increases

i think the answer is terrae but not 100 percent sure. ▓▬▬ §
