How many asymmetric centers are present in the open chain form of the aldohexose D-(-)-gulose?
bulgar [2K]

Answer:

D) 4

Explanation:

If we want to find the asymmetric centers, we must first remember that in an asymmetric center, in the carbon, we will have 4 different types of groups bonded to it.

Therefore we must look for carbons that have 4 different groups. With this in mind, we can look at each carbon.

<u>Carbon 1</u>

In this carbon, we have two bonds with the oxygen, therefore, we dont have 4 different groups. So, this is not an asymmetric center.

<u>Carbon 2</u>

In this carbon, we have an "OH" in the top, an hydrogen in the bottom a carbonyl group in the right, and a CHOH in the left. We have 4 different groups. So, this is an asymmetric center.

<u>Carbon 3</u>

In this carbon, we have an "OH" at the bottom, an hydrogen in the top, a CHOH group in the right (that is bonded to a carbonyl group), and a CHOH in the left. We have 4 different groups. So, this is an asymmetric center.

<u>Carbon 4</u>

In this carbon, we have an "OH" at the top, an hydrogen in the bottom a CHOH group in the right (that is bonded to a CHOH group), and a CHOH in the left. We have 4 different groups. So, this is an asymmetric center.

<u>Carbon 5</u>

In this carbon, we have an "OH" at the bottom, an hydrogen in the top, a CHOH group in the right (that is bonded to a CHOH), and a CH2OH in the left. We have 4 different groups. So, this is an asymmetric center.

<u>Carbon 6</u>

In this carbon, we have two bonds with hydrogens, therefore, we dont have 4 different groups. So, this is not an asymmetric center.

How many moles are in 35.6 g of H2O
klasskru [66]

Answer:

Given

mass of H2O (m) =35.6g

molarmass (mr) = H2O ), 1x2+16=18g/mol

moles of H2O (n) =?

sln

n=m/mr

n=35.6g/18g/mol

n=1.978moles

the moles of H2O are 1.978moles

HELP NOW!!
s2008m [1.1K]

Given, mass of isotope 1 = 39.06 amu

% abundance of isotope 1 = 10.00%

mass of isotope 2 =  42.14 amu

% abundance of isotope 2 = 90.00%

Average atomic mass

= [ (mass of isotope 1  x % abundance of isotope 1 ) + (mass of isotope 2 x % abundance of isotope 2 ) ]/ 100

= [(39.06 x 10) + (42.14 x 90)]/100

= (390.6 + 3792.6) / 100

= 4183.2/100

= 41.8 (to the nearest tenth)

Therefore, the weighted atomic mass of element Q is 41.8 amu.

Describe relative atomic mass​
Fynjy0 [20]
The relative atomic mass of an element is defined as the weight in grams of the number of atoms of the element contained in 12.00 g of carbon-12. To calculate the relative atomic mass of chlorine, the average mass of one atom of chlorine is found by considering 100 atoms of chlorine.


You can find the relative atomic mass by adding the number of protons to the number of neutrons for specific consideration. For example, a carbon-12 atom has 6 protons and 6 neutrons, and so has a relative atomic mass of 12.
