Answer:

Kinetic energy decreases as temperature decreases.

Explanation:

From the description that the system at 80°C has longer arrows, or move faster than the system at 20°C, having shorter actors indicating a slower motion, we can conclude that the kinetic energy of a body depends on its temperature.

If the system at 80°C shows a greater kinetic energy (faster motion of particles) than the system at 20°C, it then implies that decreasing the temperature of the body decreases its kinetic energy.

Why is the increasing amount of carbon dioxide being taken up by the oceans a cause for concern?
Anna007 [38]

Answer;

-More carbon dioxide causes an increase in carbonic acid (H2CO3) which leads to a decrease in the concentration of carbonate ion (CO32-).

Explanation;

-Carbon dioxide is added to the atmosphere whenever people burn fossil fuels. Oceans play an important role in keeping the Earth's carbon cycle in balance.

-As the amount of carbon dioxide in the atmosphere increases, the oceans absorb a lot of it. In the ocean, carbon dioxide reacts with seawater to form carbonic acid which causes the acidity of seawater to increase.

-As long as we keep putting extra carbon dioxide in the atmosphere, the acidity of the ocean will continue to increase. The effect is that; Increasing acidity makes it harder for corals to build skeletons and for shellfish to build the shells they need for protection. Corals are particularly important because they provide homes for many other sea creatures.

How does energy flow through the reef ecosystem?
Free_Kalibri [48]
Photosynthesizing plants and algae convert light energy into chemical energy, which then gets passed through the food web to plant eaters, flesh eaters, and ultimately to scavengers and decomposers.

1 Calcium carbonate breaks down on heating to produce calcium oxide and carbon dioxide gas.
Alborosie

Answer:  See below

Explanation:

1.  a)  0.15 moles calcium carbonate  (15g/100g/mole)

   b)  0.15 moles CaO  (molar ratio of CaO to CaCO3 is 1:1)

   c)   8.4 grams CaO  (0.15 moles)*(56 grams/mole)

2. a)  0.274 moles Na2O  (17g/62 grams/mole)

   b)  46.6 grams NaNO3  (2 moles NaNO3/1 mole Na2O)*(0.274 moles Na2O)*(85 g/mole NaNO3)
