The reaction between the mentioned substances can be shown as following:CaCl2 + Na2CO3 = 2NaCl + CaCO3First, the mass of CaCO3 should be converted into moles:n = m/Mrwhere n -...
Solution:The balanced chemical equation:Cu + 2AgNO3= Cu(NO3)2 + 2AgAccording to the equation: n(Cu) = n(AgNO3)/2Moles of AgNO3 = Mass of AgNO3 / Molar mass of AgNO3The molar mass of AgNO3...
. m (HCl) =30.8 g .m (NH4Cl)=? The reaction is NH4Cl= NH3 + HCl Let's find the amount of substance (HCl)= m(HCl)/ Mr(HCl) Mr (HCl)= Ar(H)+ Ar(Cl)=1+35.5= 36.5 . n=30.8/36.5=0.84...
