What is Chemistry? Chemistry is the study of matter and energy and the interactions between them. This is also the definition for physics‚ by the way. Chemistry and physics are specializations of physical science. Chemistry tends to focus on the properties of substances and the interactions between different types of matter‚ particularly reactions that involve electrons. Physics tends to focus more on the nuclear part of the atom‚ as well as the subatomic realm. Really‚ they are two sides of the

Leading zeros are not significant. Example: 0.000045 (2 sig. figs.) 5. Measured values that have trailing zeros only to the left of the decimal point are ambiguous and should be expressed in scientific notation. We must take note that the chemistry textbook (Silberberg 6e) states that placing a decimal point to the right of some trailing zeros (example: 300.) will make the zeros significant. However in General Chemistry‚ we do not follow this rule. If we want to write a whole number with trailing

A. Role of Chemistry in Society Applications of chemical science have contributed significantly to the advancement of human civilization (1‚ 2‚ 3). With a growing understanding and ability to manipulate chemical molecules‚ the post-World War II chemist was considered a societal problem solver. They synthesized crop-enhancing agricultural chemicals to ensure a constant and viable food supply. They played a significant role in the eradication of deadly diseases by developing life-saving pharmaceuticals
