<span>Incomplete combustion will occur when there is not enough oxygen to allow the fuel to react completely to produce carbon dioxide and water. It also happens when the combustion is quenched by a heat sink, such as a solid surface or flame trap.
The answer is C. Carbon dioxide.

Answer:
a simple covalent structure
Explanation:
its has a few non-metal atoms?
Answer: The event air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down would most likely take place over the next few minutes.
Explanation:
A process in which heat is evolved is called an exothermic process.
When hot metal plate at
is placed in air at room temperature then heat is given off by the metal plate due to which there will occur a decrease in kinetic energy of its molecules.
As a result, molecules in the metal will slow down.
Whereas heat is absorbed by the air molecules from the metal due to which kinetic energy of air molecules will increase.
Thus, we can conclude that the event air molecules that are surrounding the metal will speed up, and the molecules in the metal will slow down would most likely take place over the next few minutes.
Answer:
The energy of photon is 20.22×10⁻¹⁷ J
Explanation:
Given data:
Frequency of photon = 3.05×10¹⁷ Hz
Energy of photon = ?
Solution:
Formula:
E = hf
h = planck's constant = 6.63×10⁻³⁴ Js
Now we will put the values in formula.
E = 6.63×10⁻³⁴ Js × 3.05×10¹⁷ Hz
Hz = s⁻¹
E = 20.22×10⁻¹⁷ J
Thus, the energy of photon is 20.22×10⁻¹⁷ J
