One electron has a charge of -1.6* 10^-19 c
x electrons have a charge of -0.90 c
1/x = -1.6 * 10^-19 c / - 0.9 c cancel the c's. and the - signs.
1/x = 1.6 * 10^-19 / 0.9 Cross multiply
0.9 = 1.6 * 10^-19 x Divide by 1.6 * 10^-19
0.9 / 1.6 * 10^-19 = x
x = 5.625 * 10^18 electrons.
AIR PRESSURE INCREASES AS ALTITUDE INCREASES
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.
Answer: burning paper
Explanation:
The paper burns in air to form smoke and ash. which makes it a chemical change.
