why F-Xe-F bond angles in XeF4 are equal?

presence of phenopthilein indicator 25 ml (Na2CO3+NaHCO3) mixture solution HCL bureet reading 12.8ml and his dimention 1.04(N/10).then calculate dimention of Na2CO3 per liter

Six litres of 0.4M 3-(N-morpholino) propane sulfonic acid (MOPS) buffer of pH 7.8 are required. Available in the laboratory are 10M HCl and 10M NaOH and the zwitterionic form of MOPS (M.Wt = 210.3). The pKa for the MOPS zwitter ion is 7.2. Describe, showing the relevant calculations, the procedure for preparing the buffer . If 10ml of 10M HCl was added to 1 litre of the above buffer (question 9) what would be the resulting pH?
What would be the resulting pH if 10ml of 10M HCl were added to 1 litre of pure water?

A small bar of an unknown metal was left on the bench. The density of the metal is 11.5 g/cm3. An X-ray diffraction experiment was conducted to measures the edge of the face-centered cubic unit cell as 4.06 x 10-10 m. Find the atomic weight of this metal and tentatively identify this metal.

The atomic planes in a graphite crystal are separated by 335 pm. At what angle would you find the first-order (n = 1) diffraction of 0.154 nm X-rays from a graphite crystal? Shows the calculation steps.
