Write the balanced chemical equation for the following reaction. Phases are optional.
Solid iron(III) oxide reacts with hydrogen gas to form solid iron and liquid water.
anhydrous lead (II) nitrate decomposes at 400 degrees celcius to yield nitrogen dioxide, lead oxide and oxygen gas
Lead can be prepared from galena [lead (II) sulfide] by firstroasting the galena in oxygen gas to form lead(II) oxide and sulfurdioxide. Heating the metal oxide with more galena forms the moltenmetal and more sulfur dioxide.a) Write a balanced equation for each step, including the state ofeach chemical. (1) (2)b) Write an overall balanced equation for the process, includingthe state of each chemical.(c)How many metric tons of sulfur dioxide form every metric ton oflead obtained.
