Concept Introduction:
Physical properties:
The properties which are measured or observed without change in composition of matter are said to be physical properties. These includes appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity and so on.
Chemical properties:
The properties that are observed when a substance undergoes any
Qualitative properties:
The measure of the quality of something rather than its quantity is said to qualitative observation. It includes size, appearance, value and so on.
Quantitative properties:
The measure of the quantity of something rather than its quality is said to be quantitative observation. Quantity of the substance is indicated in numerical values.

Chemistry: The Molecular Science
- The molecular liquid chloroform (CHCl3) has a density of 1.48 g/mL, while the molecular liquid bromoform (CHBr3) has a density of 2.89 g/mL.(a) When 44.0 mL of CHCl3 and 39.2 mL of CHBr3 are mixed, a clear liquid solution forms. Is this a chemical or a physical change?arrow_forwardWhich piece of equipment would you use to measure 7.10 mL of CuSO4 (aq)?arrow_forwardWhat is the volume, in cubic centimeters (cm^3) of 1.00 kilograms of gold?arrow_forward
- Butane (C4H10) plus Oxygen yields carbon dioxide plus water. b. Balance the chemical equation. 2C4H10(g) + 13O2(g)→ 8CO2(g) + 10 H2O(g) c. What type of chemical reaction is it? d. Is this a physical or a chemical reaction? Please justify your answer by providing evidence from the chemical equation.arrow_forwardIodine was contaminated with salt. When the mixture was heated the iodine vapourized and the violet vapor was cooled to give solid crystals of iodine. The pure iodine was mixed with magnesium powder and heated to give a white powder. Identify all the physical and chemical changes in these proceduresarrow_forwardGive an example of a mixture in which solute is solid and solvent is liquid.arrow_forward
