An element X reacts with oxygen to form XO2 and with chlorineto form XCl4. XO2 is a white solid that melts at high temperatures(above 1000 °C). Under usual conditions, XCl4 is acolorless liquid with a boiling point of 58 °C. (a) XCl4 reactswith water to form XO2 and another product. What is thelikely identity of the other product? (b) Do you think thatelement X is a metal, nonmetal, or metalloid? (c) By using asourcebook such as the CRC Handbook of Chemistry and Physics,try to determine the identity of element X.
