Question
Indicates which of the following would be considered physical properties (P) and which would be considered chemical properties (C) of iron. (a) Iron reacts with oxygen to form iron oxides. (b) Iron melts at 1535 oC (c) When iron is immersed in 1M HCl solution, hydrogen gas is produced. (d) Iron can be polished to a high luster. The mass of 10.00 mL of carbon tetrachloride was measured to be 15.94 g. What is the density of carbon tetrachloride? (a) The density of water is 1.00 g/mL. Carbon tetrachloride is insoluble in water. Would carbon tetrachloride float on water or sink beneath water when they are combined? (b) Hexane has a density of 0.66 g/mL and is also insoluble in water. Would hexane float on water or sink beneath water when mixed with water? A student determined that an unknown liquid was soluble in an equal volume of water, had a density of approximately 0.80 g/mL and a boiling temperature of 55.5 oC. Consult Table 1 and identify the liquid The liquid is: _________Explanation / Answer
2]
Physical properties
Iron melts at 1535 degree Celsius
Iron can be polished to a high luster
Chemical properties
Iron reacts with oxygen to form iron oxides
When iron is immersed in 1M HCl solution hydrogen gas is produced
b]
The mass of 10.00 ml of carbon tetrachloride was measured to be 15.94 g. what is the density of carbon tetrachloride?
Density = Mass/Volume
D =15.94g/10mL
D =1.594g/mL
