, then east 4 miles, and then south 6 miles. The green car traveled south 4 miles and then east 4 miles. Both cars ended at the same location. Which best compares the motion of the cars? The red car traveled a shorter distance, but the displacement of the cars was equal. The green car traveled a shorter distance, but the displacement of the cars was equal. The green car had a shorter displacement, but the distance traveled by the cars was equal. The red car had a shorter displacement, but the distance traveled by the cars was equal.

Polypeptides and proteins must fold properly to be functional. Hydrogen bonds between the oxygen and nitrogen atoms of the pepti
Lubov Fominskaja [6]

Answer:

Secondary structure

Explanation:

Stricture of proteins can be categories into 4

Primary structure, secondary structure, tertiary structure and quaternary structure.

Primary structure are polypeptide chains. The polypeptide chains are formed by amino acids held together by peptide bonds.

Secondary structure refers to the folding of polypeptides chains. Two most common secondary structures are alpha helix and beta pleated structure. These folding occurs because of hydrogen bonding between the oxygen of the carbonyl of one amino acid and the hydrogen of another amino acid.

Therefore, hydrogen bonding is crucial for secondary structure of the protein.

A 0.500 g sample of phosphorous vapor exerts a pressure of 550. torr in a 73.1 mL container at 489∘C. What is the molar mass?
Korolek [52]

Answer:

Molar mass= 78.8gmol-1

Explanation:

P= 550torr, V= 0.0732dm3, m= 0.5g , R= 8.314, T= 273+489= 762K

Applying

PV= m/Mm×(R×T)

Substitute and Simplify

Mm= 78.8gmol-1

The formula B+ O2_ B2O3 is balanced as
julsineya [31]

Hey there!

B + O₂ → B₂O₃

Balance O.

2 on the left, 3 on the right. Add a coefficient of 3 in front of O₂ and a coefficient of 2 in front of B₂O₃.

B + 3O₂ → 2B₂O₃

Balance B.

1 on the left, 4 on the right. Add a coefficient of 4 in front of B.

4B + 3O₂ → 2B₂O₃

Our final balanced equation: 4B + 3O₂ → 2B₂O₃

Hope this helps!
