Valine is an essential amino acid, which means that it cannot be manufactured in the body and must be obtained through dietary s

ources. It is a branched-chain amino acid that works with the other two BCAAs (isoleucine & leucine) to promote normal growth, repair tissues, regulate blood sugar, and provide the body with energy.

Answer:

As for what is written, I think that your wording is incomplete, since valine (abbreviated Val or V) is one of the twenty amino acids encoded by DNA on Earth, whose chemical formula is HO2CCH (NH2) CH (CH3) 2. In messenger RNA, it is encoded by GUA, GUG, GUU or GUC. Nutritionally, in humans, it is one of the essential amino acids.

Explanation:

Being an essential amino acid, it speaks of the fact that the organism does not synthesize it, therefore it must be ingested in the daily diet as well as in foods rich in proteins: red meat, chicken, fish, eggs, grains and nuts.

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
igomit [66]

Answer:

0.228 L is the volume that the gas occupies after it is driedand stored at STP.

Explanation:

Pressure of the wet gas = P=695 Torr=\frac{695}{760}atm=0.914 atm

1 atm = 760 Torr

Pressure of water vapor = p = 0.0372 atm

Pressure of gas = P_1=P-p=0.914 atm-0.0372 atm = 0.8768 atm

Volume of wet gas = V_1=287 mL=0.287 L

1 mL = 0.001 L

Temperature of the wet gas = T_1=28.0^oC=28.0+273 K=301 K

Pressure of dry gas at STP = P_2=1 atm

Temperature of the dry gas at STP ,T_2= 273 K

Volume of dry gas at STP = V_2

Using combined gas law:

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

\frac{0.8768 atm\times 0.287 L}{301 K}=\frac{1 atm\times V_2}{273 K}

V_2=0.228 L =228 mL

0.228 L is the volume that the gas occupies after it is driedand stored at STP.

Which reactant is limiting?<br><br><br>Show work
fenix001 [56]

Answer:

  • 1. Iodine is the limiting reactant

  • 2. 6molAlI_3

Explanation:

<u>1. Balanced chemcial equation:</u>

      2Al+3I_2\rightarrow 2AlI_3

<u>2. Theoretical mole ratio</u>

It is the ratio of the coefficients of the reactants in the balanced chemical equation:

           \dfrac{2molAl}{3molI_2}

<u>3. Actual ratio</u>

<u />

It is ratio of the moles available to reat:

       \dfrac{9molAl}{9molI_2}

<u>4. Comparison</u>

            \dfrac{9molAl}{9molI_2}>\dfrac{2molAl}{3molI_2}

Then, there are more aluminum available than what is needed to react with the 9 moles of iodine, meaning that the aluminum is in excess and the iodine will react completely, being the latter the limiting reactant.

Conclusion: iodine is the limiting reactant.

<u>5. How much aluminum iodide will be produced?</u>

Use the theoretical mole ratio of aluminum iodide to iodide:

       \dfrac{2molAlI_3}{3molI_2}\times 9molI_2=6molAlI_3\leftarrow answer

Please help 35 points
stealth61 [152]
First one is balanced because all of the elements in reactant and product have equal number of atoms.

second one is not balanced therefore you need to add coefficient to balance it. so its CaCl2 + 2NaHCO3 = CO2 + CaCO3 + H2O + 2NaCl

both of them seem double replacement reaction

Hope it helps!

Explain why some people use the term decimal system as a synonym for the metric system?
Luda [366]

Answer:

The term Decimal is coined from the word Decimus. Decimus is a Latin word which means ‘tenth’.

The Decimal system is a system of numbering that is based on multiples of tens. It is flexible and easy to convert from one metric to another.

The preference of the term over the Metric System is because the word Metric is related more to the measurement of lengths if we looked at the origin of the word which is French.

Cheers!
