Nitrogen
Most of the nitrogen gas in our atmosphere is in this form.
What is N2?
A substance dissolved in water that forms a solution with a pH > 7.
What is a base?
All organic compounds contain this element.
These are two examples of indicators we look at when we measure the overall quality of water.
Answers Vary: (have two)
What is... microbial indicators, aquatic invertebrates, fish, pH, dissolved oxygen, heavy metals, plant nutrients, pesticides, and salt levels
This macronutrient carries our genetic information.
What are nucleic acids?
This is a result of excess nitrogen in water.
What are algae blooms?
This substance will turn a blue litmus paper into red.
What is an acid?
What is a micronutrient?
This is the process wherein which harmful substances moving up the food chain.
What is bioaccumulation?
This is the process by which water moves from a low solute concentration to an area of high solute concentration.
What is osmosis?
This is the thing we do that contributes to nitrogen in the atmosphere, resulting in acid rain.
What is burning fossil fuels?
This is what you should add to neutralize an acid.
What is a base?
This macronutrient provides energy and some cellular structure.
What are carbohydrates?
This is the parts per million you would have if you have 20g of salt in a solution of 25kg of water.
What is 800 ppm?
This macronutrient is the building blocks of cells and everything inside them.
What are proteins/amino acids?
These are the three ways that nitrogen fixation occurs.
What is nitrogen fixing bacteria, volcanoes, and lightning storms?
This is the process of adding an acid and a base together, resulting in water and salt.
What is neutralization?
This macronutrient provides energy storage an insulation.
What are lipids/fats?
This is the parts per billion when you have 0.0005g of carbon monoxide in 100g of air.
What is 5000 ppb?
Water vapour, carbon dioxide, methane, and nitrogen are known as this type of substance.
What are greenhouse gases?
These are reasons why nitrogen is important for both plants and animals. (list one reason for plants and one for animals that we've discussed in class.)
What is chlorophyll and amino acids/enzymes?
A solution with a pH of 2 is this many times more acidic than a solution with a pH of 5.
What is 1000 times more acidic?
These are compounds that contain carbon but are considered to be inorganic.
What is CO, CO2, and CN?
Or what is carbon monoxide, carbon dioxide, and cyanide?
This is what would happen to the amount of dissolved oxygen and the pH of the water if warm water was introduced.
What is a decrease in dissolved oxygen and an increase in acidity?
Copper, mercury, and lead are examples of this type of toxin.
What are heavy metals?
