Which of the following statements about the carbon cycle is NOT true?

Chemistry

horsena [70]3 years ago

Answer:

plants consume carbon through transpiration.

Explanation:

<em>Transpiration is simply a process whereby plant loses water to the environment in form of moisture or vapor. It can happen via the stomata, lenticels or cuticles of plants.</em>

Transpiration has nothing to do with plant's consumption of carbon. Plants fix carbon into their system through the process of photosynthesis during which CO2 in the atmosphere is utilized to synthesize glucose.

Carbon is an important element for all living organisms, hence, plants also needs carbon to grow.

Carbon from decomposed plants is truly a source of fossil fuel. Decayed plants form combustible geologic deposits deeply buried in the soil and ends up forming coal, crude oil, natural gas and other forms of fossil fuel.

Therefore, the only untrue option is the one claiming that plants consume carbon through transpiration.

Answer:

Plants consume carbon through transpiration

Explanation:

In transpiration, plants lose water vapor through the stomata in their leaves. No carbon is involved in transpiration, which has an outbound direction. Nothing can be consumed through the stomata when vapor is going out of the plant. It´s like trying to get in through the exit.

In class we derived the Gibbs energy of mixing for a binary mixture of perfect gases. We also discussed that the same result is
GaryK [48]

Answer:

Attached below

Explanation:

Free energy of mixing = ΔGmix = Gf - Gi

attached below is the required derivation of the

<u>a) Molar Gibbs energy of mixing</u>

ΔGmix = Gf - Gi

hence : ΔGmix = ∩RT ( X1 In X1 + X2 In X2 + X3 In X3 + ------- )

<u>b) molar excess Gibbs energy of mixing</u>

Ni = chemical potential of gas

fi = Fugacity

N°i = Chemical potential of gas when Fugacity = 1

ΔG = RT In ( a2 / a1 )

What volume of a 6.67 M NaCl solution contains 3.12 mol NaCl? L
harkovskaia [24]

Answer:

0.47dm³

Explanation

Given parameters :

Molarity of NaCl = 6.67M

Number of moles = 3.12mol

Volume of NaCl =?

Volume of NaCl = number of moles/Molarity

Volume of NaCl = 3.12mol/6.67M

Volume of NaCl = 0.47dm³

Which type of reaction is represented by the generic equation ab cd right arrow. ad cb? combustion decomposition single replacem
arsen [322]

The illustration would be that of a double replacement reaction.

<h3>What are double replacement reactions?</h3>

They are reactions in which 2 ionic compounds exchange ions to form two new products.

Thus, in the reaction: ab + cd ----------> ad + cb

ab and cd are two ionic compounds. The b in ab is replaced by the d in cd while the d in cd itself is replaced by the b in ab. Hence, new products, ad and cd, are formed.

allsm [11]
<span>A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds; or through the sharing of electrons as in covalent bonds. The strength of chemical bonds varies considerably; there are "strong bonds" or "primary bond" such as metallic, covalent or ionic bonds and "weak bonds" or "secondary bond" such as Dipole-dipole interaction, the London dispersion force and hydrogen bonding.</span>
