A common method for producing a gaseous hydride is totreat a salt containing the anion of the volatile hydride with astrong acid.(a) Write an equation for each of the following examples: (1) theproduction of HF from CaF₂; (2) the production of HCl from NaCl; (3) the production of H₂S from FeS.(b) In some cases even a weak acid such as water will suffice ifthe anion of the salt has a sufficiently strong attraction for pro-tons. An example is the production of PH₃ from Ca₃P₂ and wa-ter. Write the equation for this reaction.(c) By analogy, predict the products and write the equation forthe reaction of Al₄C₃ with water
