The explosion of an atomic bomb in the atmosphere releases many radioactive isotopes into the environment. one of the isotopes is 90sr. via a relatively short food chain, it can enter the human body. considering the position of strontium in the periodic table, explain why it is particularly harmful to humans.

Draw metallic bonding if two copper

When 13.3 g koh is dissolved in 102.7 g of water in a coffee-cup calorimeter, the temperature rises from 21.4 °c to 31.53 °c. what is the enthalpy change per gram of koh (j/g) dissolved in the water? * take the density of water as 1.00 g/ml. * assume that the solution has a specific heat capacity of 4.18 j/g*k. enter to 1 decimal place. do not forget the appropriate sign /(+). canvas may auto-delete the (+) sign
