Structure 1: 2-Butyne
Parent chain contains 4 carbons and a triple bond. So, the parent name is Butyne. Position of triple bond is written 2, as triple bond starts at carbon 2.
Structure 2: <em>cis</em>-2-Pentene
Parent chain contains 5 carbons and a double bond. So, the parent name is Pentene. Position of double bond is written 2, as double bond starts at carbon 2. As both substituents are on same side of double bond, so cis depicts the stereo.
Structure 3: <em>trans</em>-3-Decene
Parent chain contains 10 carbons and a double bond. So, the parent name is Decene. Position of double bond is written 3, as double bond starts at carbon 3. As both substituents are on opposite side of double bond, so trans depicts the stereo.
Structure 3: 1-Hexyne
Parent chain contains 6 carbons and a triple bond. So, the parent name is Hexyne. Position of triple bond is written 1, as triple bond starts at carbon 1.
Answer:
3 moles of CO are needed
Explanation:
Given data:
Number of moles of CO used = ?
Mass of Fe produced = 112 g
Solution:
Chemical equation:
Fe₂O₃ + 3CO → 2Fe + 3CO₂
Number of moles of Fe:
Number of moles = mass/ molar mass
Number of moles = 112 g/ 55.85 g/mol
Number of moles = 2.00 mol
Now we will compare the moles of iron and CO.
Fe : CO
2 : 3
Thus, 3 moles of CO are needed.
Ways to increase reaction rate:
*increase the total surface area per volume ratio
*increase the temperature
*increase the pressure
*decrease the size of particles
