Vehicle emissions devices incorporate a chemical reaction to control carbon monoxide pollution: 2co+ o2-> 2co2
what effect does adding a catalyst have for this reaction?
•it produces more carbon monoxide.
•it converts carbon monoxide faster.
•it keeps carbon monoxide from teacting.
•it keeps carbon dioxide from reacting.

Drag each number to the correct location on the equation. each number can be used more than once, but not all numbers will be used. balance the equation with the coefficients. 2 3 4 5 kclo3 -> kcl + o2

1. combine iron and copper (ii) sulfate solution. (hint: iron will form the iron (iii) ion) fe + cuso4 → 2. combine lead (ii) nitrate and potassium iodide solutions. pb(no3)2+ kl → 3. combine magnesium metal and hydrochloric acid solution. mg + hcl → 4. electrolysis (splitting) of water. h2o → 5. burning magnesium. mg + o2 →

Use the periodic table to determine the electron configuration of dysprosium (dy) and americium (am) in noble-gas notation.
