Carbon moves from one storage reservoir to another through a variety of mechanisms. For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle.
make sure to paraphrase and give thanks:) good luck
Explanation:
The gas that would behave least ideally is CO
<u>Given:</u>
A → Products
[A] M Rate(M/s)
1. 0.15 0.014
2. 0.30 0.113
3. 0.60 0.905
<u>To determine:</u>
Order of the reaction
<u>Explanation:</u>
The rate of the given reaction can be expressed as:
Rate = k [A]ⁿ-----(1)
where k = rate constant
[A] = concentration of A
n = reaction order
Based on equation (1) the Rates 1 and 2 can be expressed as:
0.014 = k[0.15]ⁿ ------(3)
0.113 = k[0.30]ⁿ-------(4)
Dividing eq (4) by (3) we get:
0.113/0.014 = [0.30/0.15]ⁿ
8 = 2ⁿ
i.e. 2³ = 2ⁿ
n = 3
Ans: Thus, the order of the reaction is 3
Answer: <em>The number placed in front of a compound to balance a chemical reaction is called </em><em><u>coefficient</u></em>.
Explanation:
Assume this general form for a <em>chemical equation</em>:
- <em>a</em>A + <em>b</em>B → <em>c</em>C + <em>d</em>D
The letters <em>a, b, c, </em>and <em>d,</em> in front of each compound A, B, C, and D, are called coefficients and indicate the number of formula units (molecules or ions) that take part in the equation.
Those coefficients are needed to <em>balance the equation</em> and ensure compliance with the law of mass conservation.
This example shows it:
- Word equation: hydrogen + oxygen yields water
- Chemical equation: H₂ (g) + O₂(g) → H₂O(g)
- Balance, adding the coefficients so that the number of each kind of atoms is the same on the left and the right of the chemical equation:
H₂ (g) + 2O₂(g) → 2H₂O(g)
In that equation:
- The coefficient of H₂ (g) on the left is 1 (it is not written)
- The coefficient of O₂(g) on the left is 2
- The coefficient of H₂O(g) on the right is 2
You read it as: 1 mole of gaseous hydrogen and 2 moles of gaseous oxygen yield 2 moles of water vapor.
Answer: Bosch process
Explanation:
Bosch process is an industrial process for the manufacture of H2. This proces uses cheap raw materials( water and coke) to generate water gas which is mixed with water in the presence of a catalyst(iron(II) oxide or chromium(iii) oxide) to generate H2
