KOH + H2CO3 → K2CO3 + H2O

#2
CaCO3 + 2HCOOH → (HCOO)2Ca + H2O + CO2

#3

#4
H+ + OH− → H2O

What will most likely happen when two bromine atoms bond together?

4. propanol and isopropanol are isomers. this means that they have a) the same molecular formula but different chemical properties. b) different molecular formulas but the same chemical properties. c) the same molecular formula and the same chemical properties. d) the same molecular formula but represent different states of the compound

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.
