Answer:
1514g of CO₂ reacted
Explanation:
Based on the reaction:
2CO₂ + 43.9kJ → 2CO + O₂
<em>2 moles of carbon dioxide require 43.9kJ of energy to produce 2 moles of carbon monoxide and 1 mole of oxygen</em>
<em />
To solve this question, we must convert the 755kJ of energy to moles of carbon dioxide that reacts and to find the mass as follows:
755kJ * (2 moles CO₂ / 43.9kJ) =34.4 moles of CO₂ are produced
<em>Mass CO₂: Molar mass: 44.01g/mol</em>
34.4 moles CO₂ * (44.01g / mol) =
<h3>1514g of CO₂ reacted</h3>
Answer :
(1) This reaction is a combustion reaction.
(2) This reaction is a decomposition reaction.
(3) This reaction is a combustion reaction.
(4) This reaction is a combination reaction.
(5) This reaction is a combination reaction.
Explanation :
Combination reaction : It is a type pf reaction in which the two or more molecules combine to form a larger single molecule as a product.
Decomposition reaction : It is a type of reaction in which a single larger compound decomposes to give two or more smaller molecules as a product.
Combustion reaction : It is a type of reaction in which a hydrocarbon molecule react with the oxygen molecule to give carbon dioxide and and water as a product.
