Which of the following lists all of the physical properties of phosphorous atom only? I. It is a yellow solid at room temperature. II. It is soluble in carbon disulfide. III. It reacts with hydrogen when heated. IV. Its density is 2.97g/cubic centimeter V. It melts at 112^circ C

The correct answer is:<br /><br />II. It is soluble in carbon disulfide.<br />III. It reacts with hydrogen when heated.<br />IV. Its density is $2.97g/cubic$ centimeter<br />V. It melts at $112^{\circ }C$<br /><br />Explanation:<br />I. Phosphorus is not a solid at room temperature; it exists as a gas.<br />II. Phosphorus is soluble in carbon disulfide.<br />III. Phosphorus reacts with hydrogen when heated.<br />IV. The density of phosphorus is $2.97g/cubic$ centimeter.<br />V. Phosphorus melts at $112^{\circ }C$.
