Answer:
239.7 g
Explanation:
Step 1: Write the balanced equation
2 LiBr + I₂ → 2 LiI + Br₂
Step 2: Convert the molecules of iodine to moles
We have 9.033 × 10²³ particles (molecules) of iodine. In order to convert molecules to moles, we will use the <em>Avogadro's number</em>: there are 6.022 × 10²³ molecules of iodine in 1 mole of iodine.
Step 3: Calculate the moles of bromine produced
The <em>molar ratio of I₂ to Br₂</em> is 1:1. Then, the moles of bromine produced are 1.500 moles.
Step 4: Calculate the mass of bromine
The <em>molar mass of bromine</em> is 159.81 g/mol. The mass corresponding to 1.500 moles is:
Answer:
THREE<span> different isomers can be derived from ethylene if two hydrogen atoms are replaced by a fl uorine atom and a chlorine atom.
Explanation:
When two Hydrogen atoms in ethylene (C</span>₂H₄) are replaced with Fluorine and Chlorine atom then the new molecular formula is C₂H₂FCl.
Compounds having same Molecular formula but different structural formula are called as Isomers.
First Isomer of C₂H₂FCl is 1-chloro-1-fluoroethene, in which F and Cl at geminal position (attached to same Carbon atom).
Other two Isomers are Geometrical Isomers of 1-chloro-2-fluoroethene, in which F and Cl at different carbon atom and having different position is space. The one in which both F and Cl at opposite side forms (<em>trans</em>)-1-chloro-2-fluoroethene and the one in which both are in same side is called as (<em>cis</em>)-1-chloro-2-fluoroethene.
