when a 0.800g sample of CaCl2 is dissolved in 9.85g of water in a microscale calorimeter the temperature of the solution rose from 23.4 degrees celcius to 35.8 degrees celcius.calc
Low grade oxide, sulphide and carbonate ores of copper are treated with dilute sulphuric acid in the existence of oxygen: CuO+ H 2 SO 4 ------------------> CuSO 4 + H 2 O CuC
Mostly compounds of d block elements exibitcolour dueto d-d transistions between partially filled eg and t2gbut the reason for colour of KmnO4 and K2Cr2O7 is due to partial chanrge transfer between central atom and oxygen which causes colour
