triangle PQR was transformed to create the congruent triangle PQR. which describes how triangle PQR could have been transformed

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.

The correct answer would be b) volume versus temperature, because they are also directly proportional.
