Answer:
Percent yield = 57%
Explanation:
Given data:
Number of moles of propane = 4.50 mol
Number of moles of carbon dioxide = 7.64 mol
Percent yield = ?
Solution:
Chemical equation:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
Now we will compare the moles of propane and carbon dioxide.
C₃H₈ : CO₂
1 ; 3
4.50 : 3×4.50 = 13.5 mol
Percent yield:
Percent yield = actual yield / theoretical yield × 100
Percent yield = 7.64 mol / 13.5 mol × 100
Percent yield = 0.57× 100
Percent yield = 57%
The answer is D.)The balloon-like device was not used in this trial.
Answer:
34- Solid
35-Metals form metallic bonds releasing one or more valence electrons to form a common electron reservoir which contains free mobile elactrons who will conduct electricity well.
36 When the cation is formed electrons are removed and the effective positive neuclear charge increases and it makes the remaining electrons accumulate around the neucleous making the cationic radius smaller than that of the atom
Answer:
protons=1
electrons=1
neutrons=0
Explanation:
protons and electrons are equal in their natural state when it goes under any reaction the protons of that element remain the same but the number of the element changes.
