Copper=54.1%, oxygen=20.1% and the balance sulfur. Could this also be the molecular formula? What other data is needed?
Explain relative electronegativities An analysis of relative electronegativities would suggest that, because C is slightly more electronegative than H, a important amount of th
Q. Reactions with metals? Ans. Halogens commonly undergo reactions with metals. Halogens react with the alkali metal family, Group IA in the periodic table. For example,
When NaCl is dissolved in water, the sodium ion become
The uncertainty in momentum of an electron is 1 x 10 -5 kgm/ s . The uncertainity in its position will be( h= 6.63 x 10 -34 Js) : (1) 5.28 x 10 -30 m
Q. Explain about Atomic Radius? The atomic size decreases with increase in atomic number along any period in the long form of the periodic table due to increase in effective n
