286.8g of carbon dioxide forms when 95.6g of propane burns. The total atomic mass of the propane is 44(g). The total mass of the carbon dioxide formed when 44g of propane is burnt is 132(g). 44 divided by 44 equals 1. 132 divided by 44 equals 3. Therefore the amount of propane to carbon dioxide is in a 1:3 ratio. Therefore, 95.6 multiplied by 3 gives you the amount of carbon dioxide formed.
The objects that could hit the atoms in the model shown are neutrons.
<h3>What is a chain reaction?</h3>
A chain reaction is a reaction that is able to sustain itself. In this case, when the neutrons collide with the fissile nucleus, more neutrons are produced which collides with more fissile nuclei thereby sustaining the reaction.
Thus, the objects that could hit the atoms in the model shown are neutrons.
