All you have to do is explain the relationship between years and inches. The most rain was in 2004 with 10 inches and the least was in 1998 with 4 inches. In recent years there has been more rain than in the past. For the analysis just summarize that.

Find the molarity: 9.82 grams of lead (IV) nitrate are dissolved to make 465 mL of solution.
solmaris [256]
Molarity is moles per liter. Therefore you must covert grams->moles by dividing 9.82 by the molar mass of lead IV nitrate. Then convert mL->L. Once you have those two numbers you can plug them into the formula Molarity = mol/L.

WILL AWARD BRAINLIEST! HELP ME OUT PLESSE! I NEED HELP WITH THIS!
marin [14]

Answer:

LiOH (aq) + VCl3(aq) ---> LiCl(aq) + V(OH)3(s) - unbalanced

3LiOH (aq) + VCl3(aq) ---> 3LiCl(aq) + V(OH)3(s) - balanced

3Li+OH- (aq) + V3+(Cl-)3(aq) ---> 3Li+Cl-(aq) + V3+(OH-)3(s) - showing ions

3Li+(aq) + 3OH- (aq) + V3+(aq) + 3Cl-(aq) ---> 3Li+(aq) + 3Cl-(aq) + V3+(OH-)3(s) (some courses don't show the charges in insoluble ionic compounds - so V(OH)3(s)) - Showing soluble ionic compounds as separate ions.

3OH- (aq) + V3+(aq) ---> V3+(OH-)3(s) (or V(OH)3(s)) - without spectator ions

Explanation:

i don't know if this is right ore not but i hope this helps even if it is just a little bit sorry if this does not help i truly apologize
