Fatty acid biosynthesis occurs through a series of reactions involving fatty acid synthase (FAS), a polypeptide multienzyme comp

lex. The result of this synthesis is a saturated fatty acid with up to 16 carbon atoms (palmitic acid). Longer fatty acids and unsaturated fatty acids result from modifications to fatty acids produced by FAS activity.What saturated fatty acid gives rise to myristoleic acid, CH3(CH2)3CH=CH(CH2)7COOH? (Complete the reaction by modifying the reactant.)

Simply put, MA = Force Out / Force in. That's the way it is usually stated. The force out is normally what you need to move. The force in is what you need to supply to get the force out. Most machines will give you an MA of more than 1. Some (like your arm) will give you less than 1 and others (like this one) will give you exactly one.

This one is frictionless, otherwise it would slip into less than one if it had friction.

penicillin. an important antibiotic (antibacterial agent), was discovered accidentally by the scottish bacteriologist alexander
dmitriy555 [2]

Answer:

mass percent of carbon       = 57.78 %

mass percent of hydrogen   = 6.40 %

mass percent of nitrogen    = 8.96 %

mass percent of oxygen    = 20.49 %

mass percent of sulfur     =  10.24 %

Explanation:

Given data

Molecular formula = C₁₄H₂₀N₂O₄S

molecular mass (total mass) = 312.39 g/mol

Percentage of carbon = ?

Percentage of hydrogen = ?

Percentage of oxygen = ?

Percentage of nitrogen = ?

Percentage of sulfur = ?

Solution

1st we find out number of moles of each element from the molecular formula

  Number of moles of carbon  = 14 mol

  Number of moles of hydrogen   = 20 mol

  Number of moles of nitrogen   = 2 mol

  Number of moles of oxygen  = 4 mol

  Number of moles of sulfur   = 1 mol

Now we find out the mass of each element

as we know that

     <em>mass = number of moles × molecular mass</em>

 mass of carbon  = 14 mol × 12 g/mol

 mass of carbon  = 168 g

 mass of hydrogen   = 20 mol × 1 g/mol

 mass of hydrogen   = 20 g

 mass of nitrogen   = 2 mol × 14 g/mol

 mass of nitrogen   = 28 g

 mass of oxygen  = 4 mol × 16 g/mol

 mass of oxygen  = 64 g

 mass of sulfur   = 1 mol × 32 g/mol

 mass of sulfur   =  32 g

now we find out the mass percent of each element

<em>         mass percent = ( mass ÷ total mass ) × 100</em>

 mass percent of carbon  = ( 168 g ÷ 312.39 g/mol ) × 100

 mass percent of carbon  = 57.78 %

 mass percent of hydrogen   = ( 20 g ÷ 312.39 g/mol ) × 100

 mass percent of hydrogen   = 6.40 %

 mass percent of nitrogen   = ( 28 g ÷ 312.39 g/mol ) × 100

 mass percent of nitrogen   = 8.96 %

 mass of oxygen  =( 64 g ÷ 312.39 g/mol ) × 100

 mass percent of oxygen  = 20.49 %

 mass percent of sulfur   = ( 32 g ÷ 312.39 g/mol ) × 100

 mass percent of sulfur   =  10.24 %

A poisoned pill contains 0.00048 moles of KCN. How many molecules are in this sample?
mario62 [17]

Answer:

2.89 \times  {10}^{20}  \:  \: molecules

Explanation:

The number of molecules of KCN can be found by using the formula

<h3>N = n × L</h3>

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

N = 0.00048 × 6.02 × 10²³

We have the final answer as

2.89 \times  {10}^{20}  \:  \:  \: molecules

Hope this helps you

What elements are in NaC2HO4 and how many atoms are in each element​
JulijaS [17]

Answer:

Each molecule contains one atom of A and one atom of B. The reaction does not use all of the atoms to form compounds.

                 A + B ⟶ Product

Particles: 6      8              6

If six A atoms form six product molecules, each molecule can contain only one A atom.

The formula of the product is ABₙ.

If n = 1, we need six atoms of B.

If n = 2, we need 12 atoms of B. However, we have only eight atoms of B, so the formula of the product must be AB.

Thus, 6A + 6B ⟶ 6AB, with two B atoms left over.

Explanation:

Credit goes to @znk

Hope it helps you :))
