A special type of combination is combustion. One of the key reactants in a combustion reaction must always involve an oxygen. This is the defining characteristic of combustion. When a combustible matter is burned, it reacts with the oxygen in air in the presence of heat. Moreover, one of its end products must be water. Let's take glucose as our example of a hydrocarbon.
C6H12O6(s) + 6O2(g) -----> 6CO2 (g) + H2O(g)
Therefore, when a solid glucose interacts with oxygen gas, it yields carbon dioxide and water vapor.
Since Na has a 1+ charge and O has a -2 charge, by reversing the charges and placing them as subscripts for the other atoms the formula is Na2O1 or simply Na2O.
Answer:
Their temperature is low
Explanation:
For gas atom moving slowly, their kinetic energy would be quite low. Low kinetic energy would result into lesser number of colliding particles and low heat being generated. Therefore, the temperature would be very low.
