The S-Enantiomer of Valine is attached below.

Assigning S-Configuration:

                                            In Valine there is only one <em>chiral carbon</em> (carbon to which all bonded atoms or group of atoms attached have different masses). This carbon also known as <em>alpha carbon</em> has a tetrahedral geometry. For S-configuration, according to<em> Cahn Ingold Prelog Rules</em> the -NH₂ group is assigned with priority order of 1, The carbon of carboxylic acid is assigned the number two and the tertiary carbon is assigned with number three. These three groups are made in such a way that moving from number 1 to number 3 makes a S sign or anticlockwise rotation while keeping the hydrogen atom behind the plane.

An analogy makes a comparison between objects based on their similar qualities. Cassidy wanted to create an analogy for the moti
valkas [14]

The correct option is B.

Matters exist in three phases, which are solid, liquids and gas. These three phases behaves differently based on their structures. Solids have definite shape and volume and their particles are tightly connected, so their particles vibrate about a fixed position. Liquids have definite volume but no shape. The inter molecular force among liquid particles is not as strong as that of solid, so the particles can move around slowly. Gases has no shape and no volume. The inter molecular force in gas particles are negligible and thus, they move about freely and randomly and fill all the available spaces.

(a) 9 cm + 2.8 cm = 11.8
Elden [556K]
 <span>For addition and subtraction you round to decimal places. 
Round the number so that it has the same number of decimal places as the number in your data that has the least number of decimal places. 

9 cm + 2.8 cm = 11.8 cm 
the 9 has no decimal places so 
= 12 cm 
(this is rounded to 0 decimal places.) 
(It has 2 sig figs) </span>
