Plsss help We mix 3.0•10^-2 mol of HNO2 with 5.0•10^-2 mol of NaNO2 and we add enough water to have 2.0L.
a) whats the pH of the solution
b) whats the reactions equation when we add HCl

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
