Will has an aquarium with water, plants, and fish that eat the plants. It is sealed so no material can get in or out, and has gl
Aleks04 [339]

Answer:

The aquarium is covered and not in sunlight

Diminishing

Explanation:

The sun is the ultimate source of energy for all life and activities on earth. The aquarium is no exception.

Green plants manufactures food in the process of photosynthesis by combining carbon dioxide and water in the presence of sunlight.

  • This food provides all other lives with energy through the break down of energy held in carbon chains.

Is the aquarium now in sunlight or is it covered?

Here is a feeding relationship between plants and fish in a pond. The producer here is the plants. The consumer is the fish.

Using carbon dioxide and water, plants manufactures food. When the amount of carbon starts decreasing it shows that the aquarium is covered.

The source of dissolved carbon dioxide in water is the fish which gives off this gas as it respires. When the fish ceases to respire, it does not have enough food and might have died thereby decreasing carbon dioxide levels.

What is happening to the number of energy storage molecules in the plants and fish as a result?

The energy levels in both plant and fish will begin to reduce because the plant is unable to produce food which the fish depends on.

This will furnish a rapid decline in the energy available in these living organisms since the plants are not able to produce.

If a sample containing 2.00 mL of nitroglycerin (density=1.592g/mL) is detonated, how many total moles of gas are produced?
fgiga [73]

The overall balanced chemical reaction for this is:

Detonation of Nirtoglycerin <span>
4 C3H5N3O9 --> 12 CO2 + 6 N2 + O2 + 10 H2O </span>

 

Therefore:

2.00 mL x 1.592 g/mL = 3.184 g <span>
3.184 g / 227.1 /mol = 0.0140 mol nitroglycerin 
4 moles --> 12 + 6 + 1 + 10 = 29 moles of gas 
<span>0.0140 mol x (29/4) = 0.1017 moles of gases or (0.102 mol) </span></span>

What volume of CH4(g), measured at 25oC and 745 Torr, must be burned in excess oxygen to release 1.00 x 106 kJ of heat to the su
anastassius [24]

Answer:

V=27992L=28.00m^3

Explanation:

Hello,

In this case, the combustion of methane is shown below:

CH_4+2O_2\rightarrow CO_2+2H_2O

And has a heat of combustion of −890.8 kJ/mol, for which the burnt moles are:

n_{CH_4}=\frac{-1.00x10^6kJ}{-890.8kJ/mol}= 1122.6molCH_4

Whereas is consider the total released heat to the surroundings (negative as it is exiting heat) and the aforementioned heat of combustion. Then, by using the ideal gas equation, we are able to compute the volume at 25 °C (298K) and 745 torr (0.98 atm) that must be measured:

PV=nRT\\\\V=\frac{nRT}{P}=\frac{1122.6mol*0.082\frac{atm*L}{mol*K}*298K}{0.98atm}\\\\V=27992L=28.00m^3

Best regards.
