Identify the substance in this table that is a liquid at STP.

Allow 1 credit for Br₂ or bromine.

Base your answers to questions 3 on the information below and on your knowledge of chemistry.

The enclosed cabin of a submarine has a volume of 2.4 × 10⁵ liters, a temperature of 312 K, and a pressure of 116 kPa. As people in the cabin breathe, carbon dioxide gas, CO₂(g), can build up to unsafe levels. Air in the cabin becomes unsafe to breathe when the mass of CO₂(g) in this cabin exceeds 2156 grams.

Convert the original air pressure in the cabin of the submarine to atmospheres.

Allow 1 credit for 1.15 atm or any value from 1.14 atm to 1.16 atm, inclusive.
