The following equilibrium is formed when copper and bromide ions are placed in a solution: heat + Cu(H2O)6 ^+2 (blue) + 4Br- → 6H2O + CuBr4^-2 (green)

Answer the following questions when KBr is added to the solution:

a. What will happen to the equilibrium?
b. What will be the color of the solution?
c. Will the solution be hotter or cooler? Explain.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
