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:
synthesis/combination
Explanation:
There are 5 main types of reactions.
combination/synthesis, decomposition, single-replacement, double-replacement, and combustion
synthesis/combination - A+B → AB
Decomposition - AB → A+B
single- replacement - A + BC → AC + B
double replacement - AB + CD → AD + CB
combustion - example - C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)
