Answer:

Sequence

Explanation:

Physical properties of the proteins are foundation of biological function of them.

A protein molecule is made up from the long chain of the amino acids. Each amino acid is linked to its neighbor by covalent peptide bond. Thus, proteins are also called as polypeptides.

Each protein has unique sequence of the amino acids, exactly same from one molecule to next. Different proteins has its own particular sequence of amino acid. This sequence is responsible for folding and binding of the protein and also its physical characteristics.

Utilizing dimensional analysis find the number of inches in a kilometer given that 1 inch equals 2.54 cm
hodyreva [135]
To solve this problem, separate it into chunks that you know. You know that there are 2.54 centimeters in 1 inch. You know that there are 100 centimeters in 1 meter. You know that there are 1000 meters in a kilometer. Therefore, we'll convert in this order: 1) from kilometers to meters, 2) from meters to centimeters, and 3) from centimeters to inches.
1) 1km × 1000m/1km
= 1000m
2) 1000m × 100cm/1m
= 100000cm
3) 100000cm × 1in/2.54cm
≈ 39370in
So, there are approximately 39370 inches in a kilometer.

If the edge length of the unit cell is 705.2 pm, what is the density of KI in g/cm3.
Kipish [7]

The density  is 3.144 g / cm^3.

<u>Explanation</u>:

If effective number of atom in NaCl type structure, z = 4

a = 705.2 pm ⇒ In centimeter = 705.2 \times 10^-10

Na = 6.023 \times 10^23

density = (molecular weight) (z) / (Na) (a^3)

where molecular weight of KI is 166 g,

           Z represents the atomic number

density = (molecular weight) (z) / (Na) (a^3)              

             = (166 \times 4) / (6.023 \times 10^23) \times (705.2 \times 10^-10)

density = 3.144 g / cm^3.

Which of the following factors affects the amount of heat absorbed by a substance?
Ilia_Sergeevich [38]

Answer:

\boxed{\text{Specific heat capacity of the substance}}

Explanation:

The formula for the amount of heat absorbed by a substance is

q = mCΔT

Thus, the three factors are the

  • mass
  • specific heat capacity
  • temperature change

The only factor that is on your list is

\boxed{\textbf{Specific heat capacity of the substance}}

The shape of the substance has no effect, nor do its melting and boiling points.

The combustion of ethane ( C 2 H 6 ) (C2H6) produces carbon dioxide and steam. 2 C 2 H 6 ( g ) + 7 O 2 ( g ) ⟶ 4 CO 2 ( g ) + 6
REY [17]

Answer:

There is a production of 11.6 moles of CO₂

Explanation:

The reaction is this:

2C₂H₆(g)  +  7O₂(g)  ⟶  4CO₂(g)  +  6H₂O(g)

2 moles of ethane reacts with 7 moles of oxygen, to make 4 mol of dioxide and 6 moles of water vapor.

If the oxygen is in excess, we make the calculate with the ethane (limiting reactant)

2 moles of ethane produce 4 moles of dioxide

5.8 moles of ethane produce (5.8  .4)/2 = 11.6 moles
