res. If the initial temperature of the gas was 305 K, what was the final temperature? Note: As long as the units for pressure and volume are the same on both sides of the equation, they will cancel. Temperature, however, must be in units of kelvin. Be sure to use the proper number of signifi A diesel engine's piston compresses 16 cm3 of fuel-air mixture into 1 cm3.

<span>Answer is: 
the final temperature was 915 K.

p₁ = 1 atm.
T₁ = 305 K.
V₁ = 16 cm³

p₂ = 48 atm.
V₂ = 1 cm³.
T₂ = ?

Ideal law gas:
p₁V₁ / T₁ = p₂V₂ / T₂.
1 atm · 16 cm³ / 305 K = 48 atm · 1 cm³ / T₂.
T₂ = 305 K · 48 atm·cm³ ÷  16 atm·cm³.
T₂ = 915 K.
p - pressure.of fuel air
T - temperature of fuel air.
V - volume of fuel air.</span>

Ethylene (C2H4) is the starting material for the preparation of polyethylene. Although typically made during the processing of p
Solnce55 [7]

Answer:

1.17 grams

Explanation:

Let's consider the balanced equation for the combustion of ethylene.

C₂H₄(g) + 3 O₂(g) → 2 CO₂(g) + 2 H₂O(l)

We can establish the following relations:

  • 1411 kJ are released (-1411 kJ) when 1 mole of C₂H₄ burns.
  • The molar mass of C₂H₄ is 28.05 g/mol.

The grams of C₂H₄ burned to give 59.0 kJ of heat (q = -59.0 kJ) is:

-59.0kJ.\frac{1molC_{2}H_{4}}{-1411kJ} .\frac{28.05gC_{2}H_{4}}{1molC_{2}H_{4}} =1.17gC_{2}H_{4}

The terms motif (fold) and domain describe levels of protein organization more complicated than primary or secondary structure.
posledela

Answer:

Each specific property of motif and domain is explained.

Explanation:

Domain;

  • May retain a 3D structure when separated from rest of the protein.          
  • Unit of tertiary structure because alpha helix and beta sheets are units of secondary structure.
  • Stable globular units like pyruvate kinase
  • May be distinct functional units in a protein

Motif;

  • Repetetive supersecondary structure because they contain cluster of secondary structure.
  • Beta Alpha Beta unit is an example of motif
  • Clusters of secondary structure

Both Motif and Domain;

  • Stabilized by hydrophobic interactions like hydrogen bonding stabilize the both.
  • Depends on primary structure like the arrangement of amino acid in polypeptide chain determine the secondary and tertiary structure of proteins.

The concept of resonance describes molecular structures Question 17 options: that have several different geometric arrangements.
kipiarov [429]

Answer:

that are formed from hybridized orbitals

Explanation:

The chemical concept of resonance is when a change in the position of the electrons occurs, without changing the position of the atoms.  

The structure obtained in the resonance will not be any of the previous ones, but a hybrid of resonance between those structures.
