Question

Write a balanced chemical equation for each of the following reactions. Check your work by balancing backwards.

 

a. Calcium phosphide reacts with water to form calcium hydroxide and phosphorous trihydride.

b. Arsenic(III) sulfide reacts with mercury(II) oxide to form arsenic(III) oxide and mercury(II) sulfide

c. Iron(II) oxide reacts with iron(III) sulfide to yield iron(III) oxide and iron(II) sulfide

Answer 1

Ca3P2 + 6 H2O --> 3 Ca(OH)2 + 2 PH3

 

As2S3 + 3 HgO --> As2O3 + 3 HgS

 

3 FeO + Fe2S3 --> Fe2O3 + 3 FeS
