I don't understand net ionic equations; for example, when you're given Pb(NO3)2(aq)+2LiCl(aq) how do you know that in the product Pb has to be paired with Cl2 and Li with NO3 to make PbCl2(s)+2LiNO3(aq)?

My teacher hasn't really talked about types of reactions; he's just given us a list of net ionic equations involving water and different elements including Lithium, Sodium, Calcium, Magnesium, Lanthanum, and Potassium to memorize. However, his test questi...

calculate the scale of a plan where 1mm represent 0.5m.

illustrate using examples the three methods of showing scale

I believe you can solve this problem by finding the LCM (least common multiple) of 6 and 8, which is 24. So it will take 24 minutes before Jose and Sara will cross the starting point together.

The expression is undefined when the denominator is equal to zero.

Thank you. My teacher hasn't really gone into much depth on types of reactions, just acids reacting with metals and water reacting with active metals.

I appreciate your patience! Thank you.
