which bonds maintain the primary structure of a protein? question 7 options: ionic bonds hydrogen bonds peptide bonds disulfide
Mariulka [41]

Proteins have four structures primary, secondary,m tertiary, and quaternary. The primary structure of the protein has been known to have peptide bonds. Thus, option C is correct.

<h3>What are peptide bonds?</h3>

Peptide bonds are the chemical bonds that are involved in protein polymer formation by linking the amino acid chains. They are also called amide bonds that are present between the nitrogen and the carbonyl atom.

The primary structure of the proteins includes the amino linked by the peptide bonds that make them look like linear structures. The secondary structures have hydrogen bonds and the tertiary have ionic and hydrophilic hydrogen bonds.

Therefore, option C. the primary structure of the protein contains peptide bonds.

6.00 g of a certain Compound X, known to be made of carbon, hydrogen and perhaps oxygen, and to have a molecular molar mass of 2
Fiesta28 [93]

Answer:

C2H2

Explanation:

Mass of Carbon in CO2= (12/44) (20.31) grams = 5.54 gram

Mass of hydrogen in H2O = (2/18)(4.26) grams = 0.46 gram

We will calculate the % of C and H in the sample  

% C = (5.54/6) * 100 = 92%

% H = (0.46/6)*100 = 7.7%

Number of mole of C = 92/12 = 7.69

Number of mole of H = 7.67/1 = 7.67

Fractional share of  C = 7.69/7.67 = 1

Fractional share of  H = 7.67/7.67 = 1

Empirical Formula = CH

Empirical Mass = 12+1 = 13

Molecular mass = 26

Molecular Formula – CHn  

N = 26/13 = 2

Molecular Formula = C2H2

Calculate the percent yield of LiHCO3 if 58.0 g of CO2 produces 79.3 g of LiHCO3
Aneli [31]

On a Space shuttle, LiOH Is used to absorb CO2 to produce LiHCO3

LiOH + CO2 === LiHCO3

Now

58g of CO2 produces 79.3g of LiHCO3

This is the Actual Yield.

Recall

% Yield = Actual yield/Theoretical yield x100

NOW

We have to find the theoretical yield

From the equation of reaction

Now 58g of CO2 reacted

Converting to Moles

mole = Mass/Molar Mass

Molar mass of CO2=44g/mol

Mole = 58/44

=1.318moles of CO2

From the equation Of Reaction.

1 mole of CO2 reacts and Produces 1 mole of LiHCO3

Since their Mole ratio is 1:1

An Equal amount of LiHCO3 will be produced.

So 1.318moles of LiHCO3 will be produced.

Convert this mole to Mass

Mole =Mass/Molar Mass

Mass = Mole x Molar Mas

Molar Mass of LiHCO3 =68g/mol

Mass = 1.318 x 68

Mass = 89.62g.

This is the theoretical Yield.

% yield = 79.3/89.62 x 100

= 88.48%.
