Which flow diagram best explains the energy transformations that occur within an automobile running on diesel

1 answer:

5 0

In diesel engines, the chemical energy in the fuel is changed to heat energy, causing the pistons to expand via mechanical energy. The mechanical energy is finally converted to kinetic energy, which is observed as the movement of the vehicle.

The production of NOx gases is an unwanted side reaction of the main engine combustion process that turns octane, C8H18, into CO

borishaifa [10]

Answer:

710,33 g NO2

Explanation:

2 C8H18 + 25 O2 → 16 CO2 + 18 H2O

(800 g octane) / (114.2293 g C8H18/mol x (25/2)) = 87.54 mol O2 used to combust the octane

$87.54 mol O2 x \frac{15}{85}$ = 15.44 mol O2 used to form NO2

O2 + 2NO → 2NO2

(15.44 mol O2) x (2/2) x (46.0056 g NO2/mol) = 710,33 g NO2

Question 5 of 10

lesya [120]

Chemical equation represents a redox reaction :

2Li + MgCl₂ → 2LiCl + Mg

<h3>Further explanation</h3>

The oxidation-reduction reaction or abbreviated as Redox is a chemical reaction in which there is a change in oxidation number

Reaction

2Li + MgCl₂ → 2LiCl + Mg

Oxidation is an increase in oxidation number, while reduction is a decrease in oxidation number.

Oxidation

$\tt Li\rightarrow Li^+(0~to~+1)$

Reduction

$\tt Mg^{+2}\rightarrow Mg(+2~to~0)$
