Answer:
The Great Lakes were formed by a retreating glacier that dug out large basins. Then as the glacier melted, the water filled in those basins
D, the rate increases as concentrations increase.
Typically, reaction rates decrease with time because reactant concentrations decrease as reactions are converted to products. Reaction rates generally increase when reactant concentrations are increased.
Temperature <span>is a measure of the average kinetic energy of particles, not just gas. </span>
H2O+Fe⇒Fe2O3+H2
When it is balanced it would be:
3H2O+2Fe⇒Fe2O3+3H2
When balancing equations, you have to make sure that all elements are equal on each side.
