In an experiment, 45g of silicon tetrachloride are treated with 45ml of water. what is the theoretical yield in grams of hcl

Consider the heating curve of h2o and line segments a, b, and c. several changes are taking place at a, b, and c. all but one would be an appropriate description as e move through segments a, b and then c.
