Answer:
Fluorine is much more reactive than chlorine (despite the lower electron affinity) because the energy released in other steps in its reactions more than makes up for the lower amount of energy released as electron affinity.
Explanation:
Answer:
2C₄H₁₀ + 13O₂ ⟶ 10H₂O + 8CO₂
Explanation:
2C₄H₁₀ + 13O₂ ⟶ 10H₂O + 8CO₂ . . . . . balanced combustion reaction
C₄H₁₀ + 5O₂ ⟶ 5H₂O + 4CO₂ . . . . not balanced
The two reactions involving Ca are not combustion reactions.
The formula equation is more meaningful than a word equation because the word equation only defines what the reactants and products are, whereas the formula equation defines which and how much of each element is present in the chemicals and also give some indication as to their structure.
One CC, or cubic centimeter, is equal to one mL, or milliliter.<span> </span>
