Answer:
The reaction has a single reactant
Explanation:
Decomposition reaction is a reaction in which an insoluble single compound is heated at a high temperature and decomposes into several products.
Typically, we may see decomposition of calcium carbonate producing calcium oxide and carbon dioxide, this is represented by the following reaction:

Another example would be decomposition of ammonium nitrite. Ammonium nitrite would decompose into nitrogen and water:

Notice that the two examples above share something in common: the two decomposition reactions have a single reactant.
<u>Answer:</u> 1.2 moles of carbon dioxide is produced for the given value of oxygen.
<u>Explanation:</u>
The chemical reaction for the combustion of acetylene follows the equation:

By stoichiometry of the reaction:
5 moles of oxygen produces 4 moles of carbon dioxide.
So, 1.5 moles of oxygen will produce =
of carbon dioxide.
Hence, 1.2 moles of carbon dioxide is produced for the given value of oxygen.
The process by which ice widens and deepens cracks in rock is called Ice welding.
I believe the answer is
At the moment it is the best way of explaining our scientific knowledge.
In the categorization of tornadoes, most tornadoes (87%) are no stronger than EF1 unless 'most' is considered 55% in which case the answer is EF0.
EF0 - 65 to 85 mph {104.61 to 136.79 km/h}EF1 - 86 to 110 mph {138.40 km/h to 177 km/h}
Hence the answer would have to be C
