mass of element is 0.5g. What is the
equivalent mass of the
element

2) 40 g/eq
3) 80 g/eq
4) None of the above​

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.
