Suppose each student in a laboratory prepares two aqueous solutions, Solution A and Solution B, then measures the conductivity of each. Predict the comparison of conductivity between the two solutions. Solution A is 10.0 mL of 0.1 M ethylene glycol. Solution B is 25.0 mL of 0.1 M ethylene glycol. Solution A contains 1.0 moles of MgCl2. Solution B contains 1.0 moles of NaOH. Solution A contains 1.5 moles of C6H12O6, Solution B contains 1.5 moles of NaCl.

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant

Can you me with this i really appreciate it

I'm learning about the periodic tables and what each subject's configuration is. for example, hydrogen is 1s^1, but i don't understand how you get that. can someone me understand how to figure out how to figure this out? sorry if the question makes no sense, but it would really a lot if you could me understand! you so much if you can!
