Answer:
C.) The coefficient of iodine is 4, oxygen is 9, and the product is 2
Explanation:
An equation is balanced when there is an equal amount of each element on both sides of a reaction. If the amounts are unequal, you can modify the amount of molecules by adding coefficients.
The unbalanced reaction:
I₂ + O₂ -----> I₄O₉
<u>Reactants</u>: 2 iodine, 2 oxygen
<u>Products</u>: 4 iodine, 9 oxygen
The balanced equation:
4 I₂ + 9 O₂ -----> 2 I₄O₉
Reactants: 8 iodine, 18 oxygen
Products: 8 iodine, 18 oxygen
Remember, coefficients are the numbers placed in front of the molecular formulas. As such, the coefficient of iodine is 4, oxygen is 9, and the product is 2.
Answer:
B. Colloid
Explanation:
Colloid is a mixture that is made up of very small homogeneous particles, thus can not be separated into fractions. Its particles do not settle as other solution, but are evenly dispersed in the medium. Some examples are: liquid milk, jelly, rubber etc
Since colloid is a solution, thus it is made up of two parts; its particles and dispersing medium.
Answer:
As we are not provided with ¹H-NMR spectrum therefore we can not conclude a single result for the minor chlorination of propane with Molecular formula C₃H₆Cl₂.
Hence, we will draw all the possible isomers with molecular formula C₃H₆Cl₂ and predict the ¹H-NMR spectrum for each of them separately.
Below is the structures of possible minor products and the NMR spectrum respectively.
Possible Product A:
If the minor product formed is 2,2-Dichloropropane then it will give only one singlet peak in NMR spectrum.
Possible Product B:
If the minor product is 1,1-Dichloropropane then it will exhibit two triplets and one multiplet as shown in figure.
Possible Product C:
If the minor product is 1,2-Dichloropropane then it will give four peaks in NMR. The extra peak is formed due to two enantiomers about the chiral carbon.
Possible Product D:
If the minor product is 1,3-Dichloropropane then it will exhibit one triplet and one quintet signal as shown in figure.
