Chemistry in Action!

Question 1:
What type of reaction is 1a? Double Replacement
What type of reaction is 1b? Corrosion
What do you think reaction 2 and 3 are? Double Replacement, Neutralization, Single Replacement


Question 2:
What is hypoxia? family of conditions characterized by a lack of oxygen in the body's tissues


When does hypoxia reach its highest levels in Long Island Sound and the Gulf of Mexico? Hypoxia reaches its highest levels in the long island sound and in the Gulf of Mexico when high levels oh phytoplankton are present.


What are the causes of hypoxia? Pollution and eutrophication in which plant nutrients enter a river, lake, or ocean, and phytoplankton blooms are reproductive, occur in the absence of pollutants.


Research the sources of high levels of nitrate ion in water bodies. Some sources of high levels of nitrate ion in water bodies are natural runoffs and septic waste. 


What are "safe levels" of nitrate in drinking water and what are the effects on humans of drinking water with high levels of nitrate ion? The “safe level” of nitrate in drinking water is 10 mg of nitrate per liter of water. The effects on humans of drinking water with high levels of nitrate ions are methemoglobinemia or blue baby syndrome. Blue baby syndrome is an illness that arises when an infant’s blood is unable to carry enough oxygen to body cells and tissue.
