B is the correct answer 9.0122
9.75 x 10^5
A number in scientific notation has the form <em>a x 10^b</em> where
• a is the <em>coefficient</em>
• b is the <em>exponent</em>
Here are the steps to convert a number greater than 1 to scientific notation.
a) Find the coefficient
Put the decimal point after the first digit and drop the trailing zeroes
<u>9.75</u> 000
The coefficient is 9.75
.
b) Find the exponent
Count the number of digits after the first digit.
In 975 000 there are five digits after the 9. Therefore, the exponent is 5.
c) Write the number
We write 975 000 as 9.75 x 10^5.
Answer:
a) 21 bonds , and 4 bonds
b) bond angles , a < 109.5° , b ≈ 120° c < 109.5° d,e < 120° f ≈ 120° g ≈ 109.5°
c) 6 carbon atom are sp² hybridized
d) two carbon atoms are sp³ hybridized,
two oxygen atoms are sp³ hybridized
Nitrogen is not sp³ hybridized , it has sp² hybridization
e) vitamin B6 exhibit delocalized bonding, because the three double bond in ring are delocalized over 5 carbon atoms and one nitrogen atom , they are formed due to 6 p orbitals of 5 carbons and 1 Nitrogen atom. The bonding in vitamin B6 is similar to the Benzene.
