Carrying capacity is _____.the ratio of predators to prey
the number of populations in a specific area
the number of organisms in a population
the number of organisms an ecosystem can support

Answers

Carrying capacity is the number of organisms an ecosystem can support. It is the maximum size of a population that can survive in the ecosystem. If the animals reach the carrying capacity, the population may crash. As the consequence, the number of animals will decrease due to predators or diseases.

The answer is: number of organisms an ecosystem can support.

Determine the density of CO2 gas at STP.

Answers

The ideal gas law is presented by the equation PV = nRT. n, the number of moles, is equal to mass over molar mass. And density is M/V.

PV = nRT

PV = (M/molar mass)RT

P/RT = (1/molar mass)(M/V)

M/V = D = (molar mass)(P/RT)

Molar mass of CO2 = 44 g/mol

D = (molar mass)(P/RT)

D = (44 g/mol)(1 atm)/(0.08206 L-atm/mol-K)(273K)

D = 1.964 g/L

What is c2h5oh and the difference between it and c2h6o

Answers

-Physical condition: C₂H₅OH is liquid; CH₃OCH₃ is a gas.
-Reactivity: C₂H₅ reacts with sodium (Na) metallic, releasing H₂ and forming the sodium ethoxide, Na (+) C₂H₅-O (-) (C₂H₅ONa).CH₃OCH₃ no reacts with sodium.-water solubility: C₂H₅OH dissolves in any proportionCH₃OCH₃ is poorly soluble in H₂O.
-polarity: C₂H₅OH is very polar, form hydrogen bonds.CH₃OCH₃ is little polar, doesn't have H available to form hydrogen bridge.
Write C₂H₆O may cause ambiguity because there are 2 different substances with this formula:-ethyl alcohol or ethanol = CH₃---CH₂---H
methyl ether = CH₃---O---CH₃

If you label a bottle only with C₂H₆O, will be very difficult to know if the compound is methyl ether or ethanol, which can be very dangerous in the laboratory. As only the ethanol C₂H₅OH is structured, it is convenient to use preferably this formula. For the methyl ether, it is more efficient to use the formula CH₃OCH₃.
