Answer:
to balance this equation, your going to put a 2 in front of the "Ca" then that makes the equation look like this "2Ca + N2 ⟶ Ca3 + N2" since the "Ca" had one atom, we added two more atoms
as we all know 1 + 2 = 3
then that gives us 3 "Ca's" on both sides
hoped this help and good luck on your test! :D

How do you think the presence of farms will affect the oxygen concentration in the ponds? im in sixth grade so i can't really comprehend to much of words lik algae or my teacher will ask me how i got educated on the topic
Answer:
The more farms the less the oxygen concentration levels. Farmers use fertilizers to increase crop growth. When algae die, bacteria break down their remains, using up the dissolved oxygen in the water. The rapid loss of oxygen, or eutrophication, can kill fish and other wildlife living in the pond or stream.

How does the temperature of water affect its ability to hold oxygen?
Answer:The solubility of oxygen and other gases will decrease as temperature increases 9. This means that colder lakes and streams can hold more dissolved oxygen than warmer waters. If water is too warm, it will not hold enough oxygen for aquatic organisms to survive.

What are some advantages and disadvantages to the acid rain management techniques?
Acid rain management techniques include protect plants from acid rain on falling on them.
What is acid rain?Rain formed when sulfur dioxide and nitrogen oxide react with chemicals in the atmosphere like water,oxygen and carbon dioxide to form sulfuric acid and nitric acid and then falling to ground containing these acids is called acid rain.
Acid rain alters the environment the environment tremendously by damaging plants and aquatic ecosystems.Plants require a specific pH of soil for their optimum growth and nutrition.
Due to acid rain, the acidity of soil increases rendering it unfit for plant growth.Similarly, pH of water also increases which affects the survival of aquatic ecosystems.
It also damages the the monuments made of metals, marbles .Taj Mahal made up of white marble has turned yellowish due to acid rain.

What evidence exists to support the idea that the composition of ocean water includes dissolved oxygen?
Answer:
The evidence that exists to support the idea that the composition of ocean water includes dissolved oxygen is that all water has oxygen in it.
Explanation:
Answer:
Fish get oxygen from water through their gills - they require oxygen to survive, so they have to be getting it from the water.
Explanation:
The concentration of dissolved oxygen and carbon dioxide are very important for marine life forms. Although both oxygen and carbon dioxide are a gas when outside the water, they dissolve to a certain extent in liquid seawater. Dissolved oxygen is what animals with gills use for respiration (their gills extract the dissolved oxygen from the water flowing over the gill filaments).
