Answer:
Carbon Monoxide
Explanation:
Fossil fuels are hydrocarbons which only contain hydrogen and carbon. 
When it is burnt in air, it reacts according to this general equation:
2(CH) + 3O2 >> H2O + CO + CO2
- Carbondioxide
 - Carbon Monoxide 
 - Water
 
 
        
             
        
        
        
Kinetic energy is is the energy of mass in motion basically the kinetic energy of an object is the energy it has because of its motion an example of kinetic energy would be, well let’s say you have a ball and you let that ball fall the potential energy then converts into kinetic energy or the energy associated with the motion and there are five types of kinetic energy like (radiant and thermal and sound and electrical and mechanical! Hopefully this help!
        
                    
             
        
        
        
The nucleus consists of the protons and neutrons. It contains the most mass in the atom. 
        
                    
             
        
        
        
Taking into account the definition of molarity, the concentration of the solution is 0.855 
.
<h3>Definition of molarity</h3>
Molar concentration or molarity is a measure of the concentration of a solute in a solution and indicates the number of moles of solute that are dissolved in a given volume.
The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution:

Molarity is expressed in units 
.
<h3>Molarity of NaCl</h3>
In this case, you have:
- number of moles of NaCl= 
1.71 moles (being 58.45 g/mole the molar mass of NaCl) - volume 2 L
 
Replacing in the definition of molarity:

Solving:
Molarity= 0.855 
Finally, the concentration of the solution is 0.855 
.

Answer :  La carga nuclear efectiva (Zef) es la carga positiva neta experimentada por un electrón en un átomo polielectrónico. El término "efectiva" se usa porque el efecto pantalla de los electrones más cercanos al núcleo evita que los electrones en orbitales superiores experimenten la carga nuclear completa
