1. 1.

   While exploring an ancient orbital laboratory, an engineer inspects a shimmering alloy sample salvaged from a deactivated reactor core. Diagnostic scans reveal that the sample has a density of 3.4 g/cm³, melts into a silvery liquid at 412 °C, deforms smoothly into thin foil under mechanical pressure, and reacts vigorously with dilute hydrochloric acid to release gas. Which of these evaluated characteristics describes a chemical property of the alloy?

   • A) Its capacity to deform smoothly into thin foil under mechanical pressure
   • B) Its tendency to react vigorously with dilute hydrochloric acid to release gas
   • C) Its sharp phase transition from a solid into a liquid at 412 °C
   • D) Its characteristic mass-to-volume ratio of 3.4 g/cm³
