Solid calcium acetate is slowly added to 125 mL of a 0.0619 M sodium hydroxide
solution. The concentration of calcium ion
required to just initiate precipitation is M.​

Calculate the molarity of the solution. 6.02 x 1022 molecules of hci (molecular weight = 36.5 g/mole) in 2.0 liters of water m

Astudent made the lewis dot diagram of a compound shown. what is the error in the lewis dot diagram? a)an o atom should transfer all of its six electrons to mg because the formula is mgo b) both electrons of mg should be transferred to one o adam because the formula is mgo c) the electrons should be transferred from each o add him to capital mg because mg has fewer electrons d) the number of dots around mg should be four because it has to transfer two electrons to each o
