Write the rate expression for following the single step reaction H2S (aq) + Cl2  S (s) + 2 HCl (aq)?

Answer 1

IF you know that the reaction occurs in a single step, then the rate expression is derived directly from the balanced equation.

For this reaction, it would be:

rate=-k[H2S][Cl2]

Answer 2

2 HCl (Acid) + Ca(OH)2 (Base) ---> 2 H2O (Water) + CaCl2 (Salt) Acid-Base neutralization reaction >> producing>> water and salt Salt as defined in Chemistry, no longer continuously table salt
