 The  molar  mass  of  Ca(NO₃)2  is 164 g/mol


<u><em> Explanation</em></u>

Ca(NO₃)2   is  made  up of   Ca  , N  and  O  elements

Therefore the  molar mass  of Ca(NO₃)2   =  molar  mass  of Ca +  molar  mass  of N +molar mass of O


from periodic table the molar mass of  Ca is 40 g/mol

for  N  =  14 g/ mol

 for  O = 16 g/mol. since they are  3 atoms  of O in  Ca(NO₃)2  the  molar mass = 16  x3 = 48  g/mol


The molar  mass   of Ca(NO₃)2 = 40 g/mo  + [(14  g/mol + 48 g/mol) 2] =164g/mol

Given the partial equation: VO2++ Mn2+ → VO2++ MnO4−, balance the reaction in acidic solution using the half-reaction method and
bezimeni [28]

Answer:

Mn^2+(aq) + 4H2O(l) + 5[VO2]^+(aq) + 10H^+(aq) ---------->MnO4^-(aq) + 8H^+(aq) + 5[VO]^2+(aq) + 5H2O(l)

Explanation:

Oxidation half equation:

Mn^2+(aq) + 4H2O(l) ------------> MnO4^-(aq) + 8H^+(aq) + 5e

Reduction half equation:

5[VO2]^+(aq) + 10H^+(aq) + 5e --------> 5[VO]^2+(aq) + 5H2O(l)

Overall redox reaction equation:

Mn^2+(aq) + 4H2O(l) + 5[VO2]^+(aq) + 10H^+(aq) ---------->MnO4^-(aq) + 8H^+(aq) + 5[VO]^2+(aq) + 5H2O(l)

Which flow diagram best explains the energy transformations that occur within an automobile running on diesel
anyanavicka [17]
In diesel engines, the chemical energy in the fuel is changed to heat energy, causing the pistons to expand via mechanical energy. The mechanical energy is finally converted to kinetic energy, which is observed as the movement of the vehicle.
