Determine the number of molecules of water, if you have 94g MoO3. According to the following reaction: 2 MoO3 + 3 Zn + 3 H2SO4 → Mo2O3 + 3 ZnSO4 + 3 H2O

the answer

explanation:

the capillary tube was too close to the bottom of the beaker.

the ruler may have moved.

water got into the capillary tube.

the temperature was not allowed to equilibrate in the 2-4 minutes.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
