The Texas Hill Country ecosystem supports a variety of organisms. Animals such as owls, coyote, snakes and hawks compete for small animals for food. What might happen if the population of these predators became too large? The predators would share the prey population equally among all of the predator species. The predators would begin to eat plants rather than their usual prey. The predators would have more offspring of great size. The predators would consume the prey population faster than it could be replaced.

Answer:Sublimation is the conversion between the solid and the gaseous phases of matter, with no intermediate liquid stage. For those of us interested in the water cycle, sublimation is most often used to describe the process of snow and ice changing into water vapor in the air without first melting into water.

Answer:

22.45g of Fe will be produced

Explanation:

The balanced reaction is:

Fe₂O₃(s) + 3CO(g) → 2Fe(s) + 3CO₂(g)

Where 1 mole of Iron (III) oxide reacts with 2 moles of Iron

To solve this question we have to find the moles of iron (III) oxide. With these moles and the balanced reaction we can find the moles of iron produced and its mass:

Moles iron (III) oxide -Molar mass: 159.69g/mol-

32.1g Fe₂O₃ * (1mol / 159.69g) = 0.201 moles Fe₂O₃

Moles Iron:

0.201 moles Fe₂O₃ * (2mol Fe / 1mol Fe₂O₃) = 0.402 moles of Fe

Mass Fe -Molar mass: 55.845g/mol-

0.402 moles of Fe * (55.845g/mol) =

When methane undergoes combustion the carbon dioxide (CO₂) and water (H₂O) is formed. Therefore, option C is correct.

A chemical reaction between two or more substances, usually involving oxygen, that produces heat and light in the form of a flame is called as combustion. The reaction is as follows:

CH4(g) + 2O₂(g) → CO₂(g) + 2H₂O

Methane burns in the presence of enough oxygen to produce carbon dioxide (CO₂) and water (H₂O). When it is burned, it produces a large amount of heat, making it an excellent fuel source.

Thus, option C is correct.

Answer:

Outside air

Nose

Lungs

Bloodstream

Cell

Explanation:

We breathe in oxygen from the outside air in through our nose and it travels to our lungs. Inside our lungs, we have Avioli's that diffuse oxygen into our bloodstream and the bloodstream helps the oxygen travel into our cells.

Hope this helps :)

Respiration is the process of exchange of gases between the cell and atmosphere. The path of respiration involves Outside Air⇒  Nose⇒ Lungs⇒ Bloodstream⇒ Cell.

Respiration is the movement of oxygen from the outside environment to the cells and the removal of carbon dioxide from the cells into the outside environment.

Respiration is of two types depending upon the presence of oxygen:

1. Aerobic Respiration: This takes place in the presence of oxygen

2. Anaerobic Respiration: This takes place in the absence of oxygen.

The path of respiration includes inspiration of outside air into the nose, through the nostrils this air is passed on to the lungs. The alveoli is the site of gaseous exchange in the lungs. In the lungs, oxygen is inspired and carbon dioxide is expired.

The oxygen gas which is inspired by the lungs is dissolved in the blood. Oxygen forms a complex with the hemoglobin protein present in the blood. This blood is then circulated to all the cells and tissues of body. Thus, the oxygen is supplied to all the cells and tissues. The path includes Outside Air⇒  Nose⇒ Lungs⇒ Bloodstream⇒ Cell.

Answer:

0.124% of Cr2O3 in the sample

Explanation:

A mass percent is expressed as 100 times the ratio of the mass of analyte and the mass of the sample. For this problem, the equation is:

Mass Cr2O3(g) / Mass Mineral(g) * 100

To solve this question we must convert the mass of Cr2O3 to grams and then, compute the value in the equation:

Mass Cr2O3 in g:

0.560mg * (1g / 1000mg) = 5.6x10⁻⁴g Cr2O3

Percent of Cr2O3 is:

5.6x10⁻⁴g Cr2O3 / 0.45g * 100

Answer:

4. D

Explanation:

Matter can exist in three states namely: solid, gas and liquid. These three states are individually unique because they possess different properties or characteristics. Matter consists of particles, which behave differently in the different states.

Particles of a liquid e.g water, ethanol etc. will move freely about in the container it is placed but in close contact with one another. This means that the particles move freely while still attached to one another. This accounts for the reason liquids are said to FLOW.

Atoms

Explanation:

According to the law of conservation of matter, matter is neither created nor destroyed, so we must have the same number and kind of atoms after the chemical change as were present before the chemical change.

Answer: The slope and y-intercept values indicate characteristics of the relationship between the two variables x and y. The slope indicates the rate of change in y per unit change in x. The y-intercept indicates the y-value when the x-value is 0.

Answer:

2800 g de ácido nítrico

Explanation:

La ecuación por la oxidación de amoniaco es:

4NH₃  +  7O₂  →  4H₂O  +  2HNO₂  +  2HNO₃

Si pensamos que el oxígeno es el reactivo limitante, trabajamos con el amoniaco. Convertimos su masa a moles:

1.36 kg = 1360 g

1360 g . 1mol  /17g = 80 moles

Si 4 moles de amoniaco pueden producir 2 moles de acido nítrico

80 moles producirán, (80 . 2)/4 = 40 moles.

Convertimos los moles a gramos:

40 mol . 63g /mol = 2520 g

Si le aplicamos la pureza

2520 g . 100/90 = 2800 g

Explanation:

Turgor pressure is the pressure forced or in other words, exerted onto the cell wall of the plant. It's caused by the movement of water into the cell. This causes the water to rush and burst into the cell, which increases the pressure onto the cell wall. Due to that, cell swells up, which helping the plant to stand upright and straight.

82.59 m/s or 297.324 km/h

Explanation:

From the question,

Applying

V = √[2(P'/ρ)].................. Equation 1 ( From

Where V = Speed of the aircraft, Differential Pressure of the air craft, ρ = Density of air at an altitude of 3000 m.

Given: P' = 3100 N/m², ρ = 0.909 kg/m³

Substitute into equation 1

V = √[2(3100/0.909)]

V = √(2×3410.34)

V = √(6820.68)

V = 82.59 m/s

V = 297.324 km/h

Hence the speed of the aircraft is  82.59 m/s or 297.324 km/h

Answer:

1.3 atm

Explanation:

Apply the ideal gas law: PV = nRT

Since we need to find the pressure, solve for pressure:

P = nRT / V

Plug in our given values of n = 4.6 moles, R = 0.08206 (ideal gas law constant using atm), T = 325 K, and V = 96.8 L:

P = 4.6(0.08206)(325) / 96.8 = 1.267 atm -> 1.3 atm (two significant figures)

Vapor Information

Explanation:

Atmospheric rivers are relatively long, narrow regions in the atmosphere like rivers in the sky that transport most of the water vapor outside of the tropics. Not all atmospheric rivers cause damage, and most are weak systems that often provide beneficial rain or snow that is crucial to the water supply.
