2h is a loosely bound isotope of hydrogen, called deuterium or heavy hydrogen. it is stable but relatively rare — it form only 0.015% of natural hydrogen. note that deuterium has z = n, which should tend to make it more tightly bound, but both are odd numbers.

What is a metal replacement reaction

Acompound has a molecular weight of 12.124 atomic mass units and the empirical formula c3h40. what is the molecular formula of the compound?

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
