Question
Chapter 3, Problem 95E
Interpretation Introduction
Interpretation:
To determine the unit for heat of fusion, if heat is measured in calories
Concept introduction:
The scope of the measurement depends upon the context and event. Measurement is commonly used as an international system of unit as a comparison framework. Two variables such as mass (m) and volume (V) can be described as directly proportional one on other by the expression m α V. Besides, the term density is the mass of the given substance per unit volume. Moreover, slope is the ratio of the change in the value of ‘y’ with respect to change in the value of ‘x’.

Read the descriptions below of two substances and an experiment on each. Decide whether the result of the experiment tells you the substance is a
pure substance or a mixture, if you can.
●
Sample A is 100. g of a coarse grey powder with a faint unpleasant smell. 15. mg of the powder are put into a very thin tube and heated. The
powder begins melting at 66.2 °C. The temperature continues to rise as the powder slowly melts, and the last of the powder becomes liquid at
76.0 °C.
Sample B is a solid yellow cube with a total mass of 50.0 g. The cube is put into a beaker filled with 250. mL of water. The cube collapses into
a small pile of orange powder at the bottom of the beaker. When this powder is filtered out, dried and weighed, it has a total mass of 29.9 g. If
the experiment is repeated with 500. mL of water, the powder that's left over has a mass of 30.0 g.
Is sample A made from a pure substance or a mixture?

- A Solution is formed when two or more substances combine to yield a mixture that is homogeneous at the molecular level. Is a container filled with water (H,O) and some beach sand (SiO2) a solution? O Yes, because SIO, dissolves completely in water to form Si(aq) and O (aq) solvated ions. O No, because water is not capable of forming homogeneous solutions. O No, because SiO, is a nonpolar covalent molecule that does not dissolve completely in water to form solvated ions. O Yes, because water reacts violently with beach sand to form H2SIO3, Metasilicic Acid, a diprotic strong acid.arrow_forwardGive the balanced chemical equation (including phases) that describes the combustion of butene, C4 H8 (g).
