Most of the carbon is put away in sedimentary carbonates and kerogens, with the rest being spread between the sea, the air, biomass, for example, plants and creatures, and petroleum products

<u>Explanation</u>:

  • The carbon cycle is the procedure where carbon goes from the surrounding into living beings and to the Earth and then again goes into the air. Plants take carbon dioxide from the air and use it for food preparation. Creatures at that point eat the nourishment and carbon is put away in their bodies or discharged as CO2 through the breath.  
  • Most of the carbon is put away in sedimentary carbonates and kerogens, with the rest being spread between the sea, the air, biomass, for example, plants and creatures, and petroleum products. This is known as carbon storage.  
  • For instance, carbon, a fundamental component in natural particles, is preserved as it is moved from inorganic carbon in a biological system to natural atoms in living life forms of the biological system and back as inorganic carbon to the earth.

Calcium nitrate reacts with sodium phosphate to form sodium nitrate and calcium phosphate. Given 96.1 grams of calcium nitrate w
Bingel [31]
Equation is:

Ca(NO3)2 + Na3PO4 —> NaNO3 + Ca3(PO4)2

Balance it out

3Ca(NO3)2 + 2Na3PO4 —> 6NaNO3 + Ca3(PO4)2

You have 96.1g of Calcium Nitrate

Moles = Mass/Molar Mass

Molar mass of Calcium Nitrate is 164.088 g/mol

96.1g / 164.088 g/mol =0.586 moles

Mole ratio is 3:1

Therefore 0.586/3 moles of calcium phosphate

Moles x molar mass = mass

0.586/3 x 310.18 g/mol = 60.6~g roughly as theoretical yield

determine the longest wavelength of light required to remove an electron from a sample of potassium metal, if the binding energy
Dafna11 [192]

Answer:

The wavelength of light is 68 nm.

Explanation:

Given data:

Binding energy of electron = 176 × 10³ Kj/ mol or   (1.76× 10⁶ j/mol)

Wavelength of light require to remove the  electron = ?

Solution:

E = hc / λ

h = planck constant (6.63×10⁻³⁴ J/s)

c = speed of light = (3×10⁸ m/s)

The energy require per electron is

1.76 × 10⁶ j / 6.02× 10²³ = 2.92 × 10⁻¹⁸ J

Now we will put the values in formula,

E = hc / λ

λ =  hc / E

λ = 6.63×10⁻³⁴ m².kg.s⁻¹ . 3×10⁸ m/s / 2.92 × 10⁻¹⁸ J

λ = 19.89×10⁻²⁶ m /2.92 × 10⁻¹⁸   (m².kg.s⁻² = J)

λ = 6.8 ×10⁻⁸ m

λ = 6.8 ×10⁻⁸ × 10⁹

λ = 68 nm

Gaseous ethane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 2.71 g of ethane is
DanielleElmas [232]

Answer:

6g

Explanation:

Step 1:

The balanced equation for the reaction between gaseous ethane and gaseous oxygen. This is given below:

2C2H6 + 7O2 —> 4CO2 + 6H2O

Step 2:

Determination of the masses of C2H6 and O2 that reacted and the mass of CO2 produced from the balanced equation. This is illustrated below:

2C2H6 + 7O2 —> 4CO2 + 6H2O

Molar Mass of C2H6 = (12x2) + (6x1) = 24 + 6 = 30g/mol

Mass of C2H6 from the balanced equation = 2 x 30 = 60g

Molar Mass of O2 = 16x2 = 32g/mol

Mass of O2 from the balanced equation = 7 x 32 = 224g

Molar Mass of CO2 = 12 + (2x16) = 12 + 32 = 44g/mol

Mass of CO2 from the balanced equation = 4 x 44 = 176g

From the balanced equation above,

60g of C2H6 reacted with 224g of O2 to produce 176g of CO2.

Step 3:

Determination of the limiting reactant.

We need to determine the limiting reactant as it will be needed to obtain the maximum mass of CO2.

From the balanced equation above,

60g of C2H6 reacted with 224g of O2.

Therefore, 2.71g of C2H6 will react with = (2.71 x 224)/60 = 10.12g of O2.

From the above calculation, we can see that a higher mass of O2 is needed to react with 2.71g of C2H6, therefore, O2 is the limiting reactant.

Step 4:

Determination of the maximum mass of CO2 produced when 2.71 g of ethane is mixed with 7.6 g of oxygen.

The limiting reactant is used to determine the maximum mass.

From the balanced equation above,

224g of O2 produce 176g of CO2.

Therefore, 7.6g of O2 will produce = (7.6 x 176)/224 = 5.97g ≈ 6g of CO2

From the calculations made above, the maximum mass of CO2 produced is 5.97 ≈ 6g

givi [52]

Answer:

The answer to your question is:  $ 35.6

Explanation:

C₆H₁₂N₂O₄Pt

Platinum = 52.5 %

Price = $1047 / troy ounce

cost of platinum = ? of 2 g

1 troy ounce = 480 grains

1 grain = 64.8 mg

Process

Get 52.5 % of 2 g

                               2 g -----------------  100 %

                               x     -----------------  52.5%

                              x = (52.5 x 2) / 100

                              x = 1.05 g

                               1 g --------------------- 1000 mg

                               1.05 g ----------------   x

                               x = 1050 mg of Pt

                               1 grain ---------------- 64.8 mg

                              x            ---------------  1050 mg

                              x = 16.2 grains

                              480 grains ---------------- 1 troy ounce

                              16.2 grains ----------------   x

                               x = (16.2 x 1) / 480

                                x = 0.034 troy ounce

                              $ 1047 ------------------  1 troy ounce

                                x        -------------------  0.034

                                x = (0,034 x 1047) / 1

                                x = $ 35.6
