up 25 % of all chlorine,
Show your calculation for the AVG. Atomic Mass of
chlorine:

Which atom or ion is the largest? a. k b. k+ c. ca d. ca2+ e. li

How are isotopes of the same chemical element alike? how are they different?

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
