The element carbon continuously Cycles through an ecosystem. A simplified carbon cycle showing Step I, where organic molecules (
nikitadnepr [17]

Answer:

See the answer below

Explanation:

Organic molecules in the form of carbohydrates are created during photosynthesis or chemosynthesis and these processes cause carbon to be removed from the atmosphere or other environment into the biosphere - the living organisms of the ecosystem.

During photosynthesis, atmospheric carbon dioxide is fixed as carbohydrates into green plants in a two-stage process that requires sunlight energy and water. The entire process can be summarized as an equation below:

6CO_2 + 6H_2O + sunlight --> C_6H_1_2O_6 + 6O_2

Instead of using water as a reactant, chemosynthetic organisms make use of high energy chemicals such as hydrogen sulfide to fix carbon dioxide in order to generate carbohydrates.

CO_2 + 4H_2S + O_2 -> CH_20 + 4S + 3H_2O

Both processes ensure that carbon dioxide moves from the environment into living organisms.

A sample of gas occupies a volume of 67.1 mL . As it expands, it does 135.3 J of work on its surroundings at a constant pressure
Semmy [17]

Answer:

V_2=1.363x10^{-3}m^3=1363mL

Explanation:

Hello,

In this case, since the work done at constant pressure as in isobaric process is computed by:

W= P(V_2-V_1)

Thus, given the pressure, initial volume and work, the final volume is:

V_2=V_1+\frac{W}{P}

Whereas the pressure must be expressed in Pa as the work is given in J (Pa*m³):

P=783Torr*\frac{101325Pa}{760Torr} =104394Pa

And the volumes in m³:

V_1=67.1mL*\frac{1m^3}{1x10^6mL} =6.71x10^{-5}m^3

Thus, the final volume turns out:

V_2=6.71x10^{-5}m^3+\frac{135.3Pa*m^3}{104394Pa}\\\\V_2=1.363x10^{-3}m^3=1363mL

Best regards.

5. The number of atoms in 9.2 g of Na will be: A. 6.2 x 1023 atoms B. 2.408 x 1023 atoms C. 9.2 x1023 atoms D. 23 atoms E. 9.2 a
cluponka [151]

Answer:

The answer is "Option B"

Explanation:

Formula:

Na atoms= Na atoms moles \times  NA

               = \frac{mass}{Na \ Molar\ mass} \times 6.022 \times 10^{23}\\\\= \frac{9.2}{23} \times 6.022 \times 10^{23}\\\\=0.2875 \times 6.022 \times 10^{23}\\\\=2.4 \times  10^{23}\ atoms \\\\
