Answer:
Carbon monoxide (CO)—a colorless, odorless, tasteless, and toxic air pollutant—is produced in the incomplete combustion of carbon-containing fuels, such as gasoline, natural gas, oil, coal, and wood. The largest anthropogenic source of CO in the United States is vehicle emissions.

<h3><u>Answer;</u></h3>
B. Fewer protons are pumped across the inner mitochondrial membrane when FADH2 is the electron donor than when NADH is the electron donor.
<h3><u>Explanation</u>;</h3>
- NADH and FADH2 are two important electron carriers in the cellular respiration process.
- NADH is a high-energy electron carrier that is reduced during glycolysis, pyruvate processing, and the citric acid cycle, and which carries electrons to the electron transport system.
- The electron transport chain passes electrons from NADH and FADH2 to protein complexes and mobile electron carriers.
Answer:
first one
Explanation:
NO ..oxidisation number is +2 and it is reduced to -3 in NH3
H2 oxidisation number is 0 and its oxidized to +1 in H2O
It is important to conserve non renewable sources of energy such as coal and oil because they are running out. If we burn all the oil to generate electricity then there will be none left for other useful things we use oil for.
The number of moles left = 0.0067 moles
<h3>Further explanation</h3>
Given
0.28 g CO
2 x 10²¹ molecules removed
Required
Number of moles left
Solution
Initial mol of CO(MW=28 g/mol) :
mol = 0.28 : 28
mol = 0.01
The number of molecules in 0.01 mol :
= 0.01 x 6.02 x 10²³
= 6.02 x 10²¹
2 x 10²¹ molecules removed, so molecules left :
= 6.02 x 10²¹ - 2 x 10²¹
= 4.02 x 10²¹
moles of 4.02 x 10²¹ :
= 4.02 x 10²¹ : 6.02 x 10²³
= 0.0067 moles
