Consider these statements about an element E in Group 4A: • The most important modern use of E is as an ultrapure semiconductor used to make microelectronic chips. . E has two main allotropes: a shiny silvery-white metal at room temperature, and a brittle gray powdery form at colder temperatures. • Although E is not a common element on the Earth's crust, deposits of the mineral EO₂ are widely found, and this ore can be reduced to E with moderate heating and charcoal. • Under standard conditions, E is a metal. Are all of these statements true about the same Group 4A element? If you said yes, what is E? Enter its chemical symbol: yes O no 0 X

The amount of sodium hypochlorite in a bleach solution can be determined by using a given volume of bleach to oxidize excess iodide ion to iodine; ClO- is reduced to Cl-. The amount of iodine produced by the redox reaction is determined by titration with sodium thiosulfate, Na2S2O3; I2 is reduced to I-. The sodium thiosulfate is oxidized to sodium tetrathionate, Na2S4O6. In this analysis, potassium iodide was added in excess to 5.00 mL of bleach (d=1.00g/cm3) . If 25.00 mL of 0.0700 M Na2S2O3 was required to reduce all the iodine produced by the bleach back to iodide, what is the mass percent of NaClO in the bleach?
