There are ionizing energy values and a radius of several particles:
al3+ - 11570 (kj/mol), 53 (pm).
mg2+- 7732 (kj/mol), 72 (pm).
na+-4565 (kj/mol), 99 (pm).
ne-2080 (kj/mol), 128 (pm).
a. (i) explain what is the difference in the radius of the particles.
(ii) explain what is the difference in ionizing energy of the given ions.
b. calculate the wavelength of the electromagnetic radiation needed to extract
an electron from the magnesium ion and give the electrons the maximum speed that equals to one thousandth
from the speed of light. show calculations.
a mixture of magnesium oxalate (mgc2o4) and calcium carbonate (caco3) was gradually heated up to
900° c in a closed vessel flattened 0.500 liters while measuring the mass of the solid.
at 400 ° c a reaction occurs:
mgc2o4(s) --> mgo(s) + co(g) + co2(g)
while in the temperature of 700 ° c there is another reaction:
caco3(s) --> cao (s) + co2 (g)
in the experiment, the mass of mgo(s) at 500 ° c was found to be 0.936 gr and the solid mass
which was measured at 900 °c and was 2.03 gr.
c.(i) calculate the partial pressure of carbon monoxide in the 500 ° c tool.
(ii) calculate the partial pressure of carbon dioxide in the 900° c tool.
