Organisms that eat cows do not obtain a great deal of energy from the cows. In fact, they get less energy than the cows obtain f

rom the plants that they eat. Why is this true? A Cows store all their energy in milk. B Cows use energy for their own metabolism. C Cows pass on most of the energy to their offspring. D Cows release all of their energy as heat.

Answer:

<em>The correct option is D) Cows release all of their energy as heat.</em>

Explanation:

Not all of the energy gets travelled from one trophic level to another. Observations have shown that only 10% of the energy travels from one trophic level to another when an organism of the upper trophic level consumes an organism of the lower trophic level. This is because most of the energy is lost by organisms as heat.

So, let's consider that there is 100% energy in plants that the cow eat. The cows will only receive 10% of the energy from the plants. The organisms that will eat the cows will only receive 1%of the energy.

An equilibrium mixture of O2, SO2 and SO3 contains equal concentrations of SO2 and SO3.
AleksAgata [21]

Answer:

[O₂(g)] = 0.0037M

Explanation:

            2SO₂(g) + O₂(g) => 2SO₃(g)

Conc:   [SO₂(g)]   [O₂(g)]     [SO₃(g)]  and  [SO₂(g)] = [SO₃(g)]

Kc =  [SO₃(g)]²/[O₂(g)][SO₂(g)]² => Kc = 1/[O₂(g)] = 270 if [SO₂(g)] = [SO₃(g)]

∴ [O₂(g)] = (1/270)M = 0.0037M

In a gas grill, 29 lbs propane C3H8 are
dimulka [17.4K]

Answer : The mass of combustion products formed are 134 lbs.

Explanation :

The balanced chemical reaction will be:

C_3H_8+5O_2\rightarrow 3CO_2+4H_2O

Given :

Mass of C_3H_8 = 29 lbs = 13154.2 g

conversion used : 1 lbs = 453.592 g

Molar mass of C_3H_8 = 44 g/mole

First we have to calculate the moles of C_3H_8.

\text{ Moles of }C_3H_8=\frac{\text{ Mass of }C_3H_8}{\text{ Molar mass of }C_3H_8}=\frac{13154.2g}{44g/mole}=298.9moles

Now we have to calculate the moles of CO_2 and H_2O.

From the balanced chemical reaction we conclude that,

As, 1 mole of C_3H_8 react to give 3 moles of CO_2

So, 298.9 mole of C_3H_8 react to give 298.9\times 3=896.7 moles of CO_2

and,

As, 1 mole of C_3H_8 react to give 4 moles of H_2O

So, 298.9 mole of C_3H_8 react to give 298.9\times 4=1195.6 moles of H_2O

Now we have to calculate the mass of CO_2 and H_2O.

Molar mass of CO_2 = 44 g/mole

Molar mass of H_2O = 18 g/mole

\text{Mass of }CO_2=\text{Moles of }CO_2\times \text{Molar mass }CO_2

\text{Mass of }CO_2=896.7mole\times 44g/mole=39454.8g=86.98lbs

and,

\text{Mass of }H_2O=\text{Moles of }H_2O\times \text{Molar mass }H_2O

\text{Mass of }H_2O=1195.6mole\times 18g/mole=21520.8g=47.44lbs

The total mass of products = Mass of CO_2 + Mass of H_2O

The total mass of products = 86.98 + 47.44 = 134.42 ≈ 134 lbs

Therefore, the mass of combustion products formed are 134 lbs.
