If it is incomplete or complete combustion. Normally the problems question with tell you. 
EX: 
"In the presence of plenty of oxygen" is complete combustion 
"Not enough oxygen present" is incomplete combustion
        
             
        
        
        
The term isoelectronic atoms means that if the given atoms are neutral, they would have the same number of electrons, which is relative to their sizes. Ions with positive charges are called cations, losing electrons. On the other hand, ions with negative charges are called anions, gaining electrons. The more electrons that the atoms have, the bigger it is in size. Hence, the arrangement of the radii of the atoms would have to be,
      e²⁺, d⁺, c , b⁻, a⁻
The arrangement is from smallest to largest.

Electric motors are an essential part of our daily life as many systems, applications, and services depend on them. Motors today have a long service life and require a minimum level of maintenance to make sure that they perform efficiently. In large buildings, motors have to be maintained on a regular basis because they need to be in operation all the time; one small problem could cause a great loss to the organization.
Usually in large organizations, a motor maintenance program is carried out in which the causes of motor failures are identified and some necessary steps are taken to avoid them or lower their impact. Motors need to be inspected regularly, and other maintenance activities need to be performed to ensure efficient operation. Whenever a problem occurs, it should be corrected immediately to avoid further loss.
 
        
             
        
        
        
The scientist who studies the earth constituent like solids, gas and liquid is called a geologist. Weathering and erosion are the correct blanks. 
<h3>What are weathering and erosion?</h3>
The process of the deterioration of any solid particles like minerals, soils and rocks is called weathering. It occurs due to biochemical substances, atmospheric gases and water pressure.
The process of the transportation of the rocks and mineral particles away from their original position is called erosion it is due to forceful air and water.
The rocks moved from their original place to some another due to weathering and this process of their transportation is called erosion.
Therefore, <u>weathering </u>and <u>erosion </u>are the correct blanks.
