When iodide ions (I-) are added to a solution of iron(III) ions (Fe3+), an equilibrium mixture is formed. a) State a colour change you would expect to see when aqueous iodide ions, I- (aq), are mixed with aqueous iron(III) ions, Fe3+(aq)?

b) What ions are present in the equilibrium mixture?

c) Describe a simple chemical test you could carry out to show the presence of iodide ions, I- (aq), in the equilibrium mixture?

If you have 5.25 grams of methane (ch4), how many grams of co2 will you produce ?

Why does the sun appear to be the brightest star in the sky? a- its apparent brightness is much greater than other stars. b- it burns more gas, making it brighter than any other star. c- it is the largest star in the galaxy, so it is the brightest star. d- its relative distance to earth is closer than the other stars.

Ammonia and oxygen react to form nitrogen monoxide and water, like this: 4nh3 (g) + 5o2 (g) → 4no (g) + 6h2o (g) also, a chemist finds that at a certain temperature the equilibrium mixture of ammonia, oxygen, nitrogen monoxide, and water has the following composition: compound pressure at equilibrium nh3 65.1atm o2 31.3atm no 62.7atm h2o 65.8atm compound pressure at equilibrium nh3 65.3 atm o2 7.79 atm no 12.1 atm h2o 65.8 atm calculate the value of the equilibrium constant kp for this reaction. round your answer to 2 significant
