<span>It depends on what was being combusted.
Supposing the simplest case, where carbon is being burnt:
C + O2 → CO2
(9.0 mol O2) x (1 mol CO2 / 1 mol O2) = 9.0 mol CO2
The answer would be different if the fuel contained any oxygen atoms, for example, alcohol.</span><span>

A day is added to February every four tears as a corrective measure. The Earth does not exactly revolve around the sun for 365 days. There is a small offset that is corrected by adding a day to February. This happens every four years and it is called Leap year.
To change solar energy to chemical energy is the answer!
Answer:
i.e belongs to same group because of valence electrons are same
Explanation:
so it has same chemical behaviour. and q has more energy than r ionisation energy decreases from top to bottom
Answer:
The process of dissolving can be endothermic (temperature goes down) or exothermic (temperature goes up).
When water dissolves a substance, the water molecules attract and “bond” to the particles (molecules or ions) of the substance causing the particles to separate from each other.
The “bond” that a water molecule makes is not a covalent or ionic bond. It is a strong attraction caused by water’s polarity.
It takes energy to break the bonds between the molecules or ions of the solute.
Energy is released when water molecules bond to the solute molecules or ions.
If it takes more energy to separate the particles of the solute than is released when the water molecules bond to the particles, then the temperature goes down (endothermic).
If it takes less energy to separate the particles of the solute than is released when the water molecules bond to the particles, then the temperature goes up (exothermic).
