A new neighborhood is built close to an old, abandoned landfill that is no longer in use. What impact could this have on the land near the neighborhood? Ash from burning trash may wash into local waterways. Residents are exposed to asbestos, cadmium, or lead. Leachate that leaks underground can release into the air. Residents are exposed to lead gas through contact with soil.

Gucchi:

Imagine you are in a laboratory. You are exploring the following reaction: A + B → C When the product C is created, bubbles form. When 10mL of A is added to 10mL of B, the reaction takes twenty seconds. Your teacher gives you three unknown substances (X, Y, and Z), one of which is a catalyst for the reaction. Design an experiment to test substances X, Y, and Z to determine which one is a catalyst for the reaction.

Gucchi:

??

Aqual:

i would say it would be either a or c bc those are the land impacts

Aqual:

the others are about the residents

Aqual:

it would be c bc they wont be burning trash at an abandoned landfill
