Predict the coordination number of ca2+ in cao crystal aane also its Crystal structure.

A. Anode: F2; Cathode: NaB. Anode: O2; Cathode: H2C. Anode: O2; Cathode: CaD. Anode: O2; Cathode: H2E. Anode: S; Cathode: H2F. Anode: S; Cathode: Na

Number of moles =4.5moles

C) Tertiary structure

∆Hrxn = ∆H1 + ∆H2= -635+178= -457kJ

A crystal structure is characterised by the positions of all the atoms in the unit cell, including the symmetry relations between atoms and the dimensions of the unit cell. (In...

=1.68g of CaCO3

The coordination number of Na+ is of 4. Since the charge of anion is in two times larger than for cation the coordination number of O2- must be 8. This...

1 mg (0.001g) in 1000 ml is one ppm. 2 mg Ca2+ in 500 g (500 mL) is:2 mg / 0.5 L = 4 ppm

n=m/M*2=0.675g/40*2=0.03375mol c=n/V*1000=0.03375/1.925l*1000=17.5mEq/L

Solution:Parts Per Million (ppm) is a measurement of the concentration of dilute solution.In weight/weight (w/w) terms 1 ppm = 1 mg solute / 1 kg solution.Convert the mass of the...
