Combustion, or drag and drop answer here, is an example of one of the most familiar chemical changes. Melting of ice, likewise, is one of the most
common examples of physical changes. When a piece of coal burns, drag and drop answer here combines with the carbon in the coal The products are
carbon dioxide gas, water vapor, and a lot of ash. After careful measurements are taken, the drag and drop answer here of the reactants (coal and
oxygen) is drag and drop answer here to the mass of the products (carbon dioxide, water vapor, and ash). During the drag and drop the reaction,
the quantity of matter is unchanged. Similarly, when 10 grams of ice drag and drop answerda drag and dreamwe hare grams of water is obtained.
Mass is ding and drop w here in this drag and did answer change as well
