Discover the molar mass for compounds such as Strontium Hydroxide Dinitrogen Trioxide Sodium Chlorate and Chromium(III) Oxide. A concise guide to understanding molar masses and their real-world applications.

Understand the fundamental distinctions between pure substances and mixtures. Unpack the definitions and real-world examples of elements, compounds, homogeneous, and heterogeneous mixtures.

The scenario involves an archaeologist analyzing iron in an old building containing nickel-63, which has a known half-life of 92 years. With only 0.78% of the original nickel-63 remaining, the goal is to estimate the year when this discovery was made. We delve into the calculations and principles of first-order decay reactions.

Explore how to determine the oxidation states of Chlorine in various ions using fundamental rules in chemistry. Learn the importance of oxidation numbers in understanding chemical reactions and the art of balancing chemical equations.

Discover the differences between physical and chemical changes using common examples. Understand how sugar reacts in various scenarios, and how metals undergo changes, either maintaining their substance or forming new compounds.
