Which of the following is NOT a difference in the pathways by which fatty acids are degraded
and synthesized?
A. The location of the process
B. The presence or absence of a double bond
C. The molecule to which the chain being synthesized or degraded is attached
D. The number of carbons added or removed to elongate or shorten the existing fatty acid
chain

Answers

Answer 1

The presence or absence of a double bond is not a difference in the pathways by which fatty acids are degraded and synthesized. Therefore, option B is correct.

What is fatty acid ?

A fatty acid is an aliphatic carboxylic acid having a saturated or unsaturated aliphatic chain. The majority of fatty acids that are found in nature contain an unbranched chain with an even number of carbon atoms, ranging from 4 to 28.

Triglycerides, cholesterol, and other critical fatty acids—what the medical community refers to as fats that the body cannot produce on its own—store energy, keep us warm, and safeguard our vital organs. They serve as messengers, facilitating the work that proteins do.

Thus, option B is correct.

Which of the following equations follows the law of conservation of mass?

Answers

Answer:

[tex]\boxed {\boxed {\sf 2 K + Cl_2 \rightarrow 2KCl}}[/tex]

Explanation:

The law of conservation of mass states that mass cannot be created or destroyed. The mass of the reactants must equal the mass of the products. Basically, the number of atoms at the beginning is the same as the end.

Count up the atoms on the left and right sides of the arrow. Remember to account for coefficients and subscripts.

1. 2Fe+3O₂⇒Fe₂O₃

Right: 2Fe + 3O₂

2 Fe atoms and 6 O atoms (3 * 2 per molecule)

Left: Fe₂O₃

2 Fe atoms and 3 O atoms NOT balanced

2. 2H₂+ O₂ ⇒ 2H₂O₂

Right: 2H₂+O₂

Left: 2H₂O₂

4 H atoms and 4 O atoms (2*2 per molecule for both) NOT balanced

3. 2K+Cl₂⇒ 2KCl

Right: 2K + Cl₂

How many grams (g) are in 4.00 moles of Carbon (C) ?

Answers

Answer:

There are 36 grams in 4.00 moles of Carbon.

Explanation:

In order to convert from moles of a substance into grams of the same substance, we need to use the substance's molar mass.

That means that in this case we use the molar mass of Carbon:

4.00 mol * 12 g/mol = 36 g

Thus, there are 36 grams in 4.00 moles of Carbon.

Consider the reaction of tin with potassium hydroxide and water. Sn (s) 2KOH (aq) 4H2O (l) K2Sn(OH)6 (s) 2H2 (g) Determine the limiting reactant in a mixture containing 122 g of Sn, 134 g of KOH, and 63.9 g of H2O. Calculate the maximum mass (in grams) of potassium hydroxystannate, K2Sn(OH)6, that can be produced in the reaction. The limiting reactant is:

Answers

Answer:

The limiting reactant is: H₂O

265.3 g of K₂Sn(OH)₆ are formed in the reaction.

Explanation:

The reaction is:

Sn(s) + 2KOH (aq) + 4H₂O(l)  → K₂Sn(OH)₆ (s) + 2H₂ (g)

The first step to solve is to determine the moles of each reactant:

We controlled that reaction is ballanced.

122 g . 1mol / 118.71g = 1.03 moles of Sn

134g . 1mol /56.1g = 2.39 moles of KOH

63.9 g .1mol /18g = 3.55 mol of water

Stoichiometry is 1:2:4.

Sn is the lowest reactant and water, the highest, but I can see, that water is the limiting.

1 mol of Sn needs 4 moles of H₂O to react

Then, 1.03 moles of Sn may react to (1.03 . 4)/1 = 4.12 moles.

We only have 3.55 moles. It's ok.

2 moles of KOH need 4 moles of H₂O to react

Then, 2.39 moles of KOH may react to (2.39 . 4) /2 = 4.78 moles.

We only have 3.55, there's no enough water.

So 4 moles of water can produce 1 mol of potassium hydroxystannate

Then, 3.55 moles of H₂O may produce (3.55 . 1)/4 = 0.8875 moles.

We convert moles to mass: 0.08875 mol . 298.91g /1mol =265.3g

Two students come up with an idea they think will save time: We just used the fast titrations. You can stop the video when the solution turns pink. We know that when the solution turns pink, the titration is complete, so we just read the volume from the burette as soon as it turns pink. This is faster than going through all the shorter videos and works just as well. Is this method just as accurate as using the slow titrations

Answers

Answer:

Yes.

Explanation:

Yes, this method is accurate just as the slow titration because in both type of titrations we want to measure the point at which the indicator change the colour of the solution. Both fast and slow titrations are the same in their function i.e. both tell us the point or the amount at which the indicator change the colour of the solution so we can conclude from this discussion that fast titration gives the same result just as the slow titration.

Explanation:

A cylinder of compressed gas rolls off a boat and falls to the bottom of a lake. Eventually it rusts and the gas bubbles to the surface. A chemist collects a sample of the gas with the idea of trying to identify the gas. The wet gas collected occupies a volume of 283 mL at a pressure of 745 torr and temperature of 28.0oC. The vapor pressure of water at 28.0oC is 0.0372 atm. 1. Calculate the volume (L) that the gas occupies after it is dried (the water vapor removed) and stored at STP. Tries 0/99 The mass of the dry gas is 905 mg. A fragment of the tank indicates that the gas is a monoatomic element. 2. Write out the full name of the gas.

Answers

Answer:

See explanation

Explanation:

From the information given;

We convert the pressure from torr to atm as follows;

745 torr * 1 atm/760 torr = 0.98 atm

Initial pressure P1 =  0.98 atm - 0.0372 atm = 0.9428 atm

Initial volume V1=  283 mL

Initial temperature T1 = 28.0oC + 273 = 301 K

Final volume V2 = ??

Final Temperature T2 = 273 K

Final pressure P2 = 1 atm

From the general gas equation;

P1V1/T1 = P2V2/T2

P1V1T2 = P2V2T1

V2 = P1V1T2/P2T1

V2 = 0.9428 * 283 * 273/1 *  301

V2 = 241.99 mL or 0.24 L

If 1 mole of gas occupies 22.4 L

x moles of gas occupies 0.24 L

x =  1 mole  * 0.24 L/ 22.4 L

x = 0.0107 moles

But number of moles = mass/molar mass

molar mass = mass/number of moles

molar mass = 905 * 10^-3g/0.0107 moles

molar mass = 84 g/mol

The monoatomic gas is Krypton

b) For molecules with fourbr more stereocenters, the two epimers can interconvert by selected bond rotations
c) Rotation around bonds will not alter the chirality of a stereocenter )
d) A sing le rotation around each of two specific bonds of a stereocenter will alter the chirality at that stereocenter.

Answers

Answer:

Option c) is correct

Explanation:

No, it is not possible to convert one sugar to the other without breaking covalent bonds as rotation around bonds will not alter the chirality of a stereocenter.

(A stereocenter refers to any point in a molecule that consists of various substituents, such that as two substituents are interchanged, it results in a stereoisomer.)

Therefore,

The subscript 1 stands for the initial conditions and 2 for the final conditions.

In this case:

P₁ = ?V₁ = 300.0 mLP₂ = 30.0 mm HgV₂ = 100.0 mL

Precipitation is defined as any liquid or frozen water which forms in the atmosphere and then gets received on Earth.It is one of the most important steps of the water cycle.

Precipitation takes place in form of clouds when water vapor gets accumulated in clouds and they get bigger and heavy, when the clouds become heavy enough they fall to the land in the form of rain.f a cloud is present at higher altitudes , the water present in the clouds freezes and fall to the ground in form of snow,hail.

Precipitation occurs always in case of fresh water because the sea salt does not evaporate with the water.The different types of precipitation are rain, drizzle,snow,snow hail,etc.

What volume (in mL) of concentrated HCl (12 M) is needed to make 1500 mL of a 3.5 M solution?

Answers

Answer:

437.5 mL

Explanation:

Concentration (c) = Moles (n) / Volume of solution (liters)

C = n / V

rearrange the formula to find out how many moles you need in the final solution.

n (moles) = concentration (c)   x   Volume (V)   ( in liters)

Convert your mL into L.  1500mL is 1.5L

n = 3.5 moles/liter  x  1.5 liters  (the liters cancel each other out)

n = 5.25 moles

Now use the same formula to calculate the volume you need to make the final solution based on the concentration of the original.

c = n/V  or   V = n / c

V = 5.25 moles / 12 moles/liter     here the moles cancel out

V = 0.4375 L

convert back to mL

V = 437.5 mL
