<span>Answer:
             Molecules that are optically active due to the tetrahedral arrangement of bonds around the carbon atom are often referred to as <u>Chiral Molecules</u>.

Explanation:
                   Chiral molecules have stereogenic centers. When plane polarized light is fall on these compounds they rotate the light either in clockwise or anti clockwise direction. The mirror images of chiral moleculecules are non-superimposable.  Below few examples for molecules containing chiral centers are given.</span>

Explain why the grams of the nutrient molecules in a food do not add up to the total gram weight of the food.
leva [86]

When we talk about the gram weight of any food item, it may or may not include the gram weight of its different nutrient molecules. It may have different reasons to it. One of the reasons can be because the nutrient molecule might contain a large percentage or proportion of water. Also, the nutrient molecules might be insoluble or indigestible fiber so it does not add up to the total gram weight of food.

How do you calculate the number of valence electrons in an atom?
gavmur [86]
To find<span> the </span>valence electrons in an atom<span>, identify what group the element is in. An element in group 1A has 1 </span>valence electron<span>. For example, Li is in group 1A, so that means it has one </span>valence electron. If the element is in group 2A, then it has two valence electrons<span>.</span>

If there are 40 mol of NBr3 and 48 mol of NaOH, what is the excess reactant
Vanyuwa [196]
<h3>Answer:</h3>

              Excess Reagent =  NBr₃

<h3>Solution:</h3>

The Balance Chemical Equation for the reaction of NBr₃ and NaOH is as follow,

                       2 NBr₃ + 3 NaOH   →   N₂ + 3 NaBr + 3 HBrO

Calculating the Limiting Reagent,

According to Balance equation,

               2 moles NBr₃ reacts with  =  3 moles of NaOH

So,

           40 moles of NBr₃ will react with  =  X moles of NaOH

Solving for X,

                       X  =  (40 mol × 3 mol) ÷ 2 mol

                       X  =  60 mol of NaOH

It means 40 moles of NBr₃ requires 60 moles of NaOH, while we are provided with 48 moles of NaOH which is Limited. Therefore, NaOH is the limiting reagent and will control the yield of products. And NBr₃ is in excess as some of it is left due to complete consumption of NaOH.
