HURRY 1. When aqueous solutions of lead(II) nitrate (Pb(NO3)2) and sulfuric acid
(H2SO4) react, lead(II) sulfate forms as a precipitate. Identify the spectator
ions and write a balanced net ionic equation for this reaction.

The ions Pb2+ and SO42- combine to form the precipitate.

Which two ions are spectator ions?

The net ionic reaction is Pb2+ + SO42...

How many atoms are in 2 moles of phosphorus?

Calcium carbonate decomposes at high temperatures to give calcium oxide and carbon dioxide as shown below. caco3(s) cao(s) + co2(g) the kp for this reaction is 1.16 at 800°c. a 5.00 l vessel containing 10.0 g of caco3(s) was evacuated to remove the air, sealed, and then heated to 800°c. ignoring the volume occupied by the solid, what will be the mass of the solid in the vessel once equilibrium is reached?

Alice did an experiment to find the relationship between the angle at which a ray of light strikes a mirror and the angle at which the mirror reflects the light. she placed a ray box in front of a mirror. she changed the angle at which the light from the ray box struck the mirror and noted the corresponding angle at which the mirror reflected the light. which of the following is the dependent variable in this experiment? the mirror used to reflect the light the ray box used as the source of light angle at which the light from the ray box strikes the mirror angle at which the mirror reflects the light from the ray box
