Hello!
First, we can model the chemical reaction in the following way:
nA(g) ⇄ mB(g)
Now, we can start answering the two questions:
1) D<span>etermine if the reaction is endothermic or exothermic:
The reaction is endothermic. We know that because the fraction of products is increased when the temperature is increased. According to Le Chatelier's principle, the system will move in the opposing direction of the changes to establish a new equilibrium. We can model an endothermic reaction in the following way, knowing that it needs heat to be completed
</span>nA(g) + Δ ⇄ mB(g)
So, adding heat in the left side of the reaction will displace the equilibrium in the opposing direction (the right side) increasing the fraction of products.
2) D<span>etermine which side of the equation has more molecules:
The right side of the equation has more molecules than the left side. According to Le Chatelier's Principle, in a gas phase reaction, increasing the volume results in a decrease in the internal pressure of the system, so the reaction shifts to the side with more molecules to restore the pressure of the system. As the fraction of products increases with the increase in volume, the right side will have more molecules. We can then express this reaction in the following way:
</span>nA(g) ⇄ mB(g) n<m
Have a nice day!
Decomposition is the process of degradation or break down of organic matter such as cellulose or other polysaccharide to simpler unit or monosaccharide. Usually decomposition takes place in absence of oxygen such as anaerobic decomposition. The decomposition results in evolution of carbon dioxide by degrading the C , H and O of organic matter with the help of bacterias ro microorganisms.
Thus, with decomposition, the level of carbon dioxide increases.
Steel is a homogenous mixture, therefore it is made from iron and carbon. steel is not a substance it is a mixture! hope that helped :)
Answer:
i think its a mixture because it has different things mixed with it like chocolate, marshmallows and other stuff
Explanation:
