What is the main difference in the physical properties of metals and non-metals? Which of these sets of minerals is not an example of polymorphs? (a) Gold and silver (b) Diamond and graphite (c) Calcite and aragonite. What are the two...
Describe how the properties of the different types of elements (metals, nonmetals, metalloids) differ. Why atoms in the same group on the periodic table act similar chemically to one another? Why does a material containing n--->pi^* transitions make a poor dye? Why do different ...
States of Matter:Matter may exist in three fundamental states in the physical sciences: solid, liquid, and gas. These states are the outcome of particle arrangement and motion at the molecular or atomic level. Matter may change between these states by varying the temperature and pressu...
A physical property of a chemical species is a property that does not relate to its change in composition. Some examples of physical properties include density, boiling point, freezing point, physical state of the matter at room temperature, hardness, and conductivity. Other examples of ph...
Describe briefly why the study of electromagnetic radiation has been important for an understanding of the arrangement of electrons in atoms. Why is a salt bridge necessary in galvanic cells? A battery is made of two half cells that have a combined E0 of 1.8 volts. Is the voltage ...
The hydrogen atoms in H2 were created during the Big Bang. In the early universe, only hydrogen atoms existed. It was only later when gravity pooled the hydrogen to create stars that heavier elements were created.Answer and Explanation: Two physical properties of hydrogen (H2) are: ...
