Chlorine has less valence electrons than bromine, and, therefore, needs to bond with another atom to become more stable .
The rate of change of the temperature of the Earth's surface is given to,
90°F/mile
To determine the temperature x miles away from the surface, we multiply the depth by the given rate. This will give us the answer of,
T = (90°F/mile)(90 mile)
= 8100°F
Thus, the temperature 90 miles deep in the Earth's surface is equal to 8100°F.
Physicalchange. Lighting a match and letting is burn is an example of a chemical change. Chemical reactions cause chemicalchanges. In a chemical reactiontwo or more substances, called the reactants, form different substances called products.
