If mercury (Hg) and oxygen (O2) were reacted to form mercury oxide how many molecules of each reactant and product would be need
dimulka [17.4K]
In order to get HgO you would need 2Hg+1O2=2HgO. Since oxygen is diatomic you need two when it stands alone causing you to need two mercuries to balance out the reactants and the product I hope this helps

Complete Question

The complete question is shown on the first uploaded image  

Answer:

The density is  \rho =  8.21479 g/cm^3

Explanation:

From the question we are told that

         the lattice constant is  a =  0.295 nm = 0.295*10^{-9} = 0.295*10^{-7} cm

The density of Copper (\beta) is mathematically represented as

     \rho  =  \frac{ZM}{a^3N_A}

Where  Z is the number of units in a unit cell and  for BCC crystals  Z =2

          M is the molar mass of copper which same for Copper with a value of  

           M =  63.5  g/mol

          N_A is the Avogadro's constant with a value of  N_A =  6.022*10^{23}

Substituting values

       \rho =  \frac{2 *63.5}{(0.295*10^{-7})^3 * (6.022*10^{23})}

      \rho =  8.21479 g/cm^3
