Answer:

2.41 Litres

Explanation:

Using the combined gas law equation as follows;

P1V1/T1 = P2V2/T2

Where;

P1 = initial pressure (atm)

P2 = final pressure (atm)

V1 = initial volume (L)

V2 = final volume (L)

T1 = initial temperature (K)

T2 = final temperature (K)

According to the information provided in this question;

P1 = 1 atm

P2 = 0.65 atm

V1 = 1.75 liters

V2 = ?

T1 = 21°C = 21 + 273 = 294 K

T2 = -10°C = -10 + 273 = 263 K

Using P1V1/T1 = P2V2/T2

1 × 1.75/294 = 0.65 × V2/263

1.75/294 = 0.65V2/263

Cross multiply

294 × 0.65V2 = 1.75 × 263

191.1 V2 = 460.25

V2 = 460.25 ÷ 191.1

V2 = 2.41 L

Most protein enzymes catalyze only one specific chemical reaction effectively. What feature of protein structure is most directl
babunello [35]

Answer;

d. the specific geometry and types of amino acids in the active site

Explanation;

-Enzymes are highly selective catalysts, meaning that each enzyme only speeds up a specific reaction. The molecules that an enzyme works with are called substrates. The substrates bind to a region on the enzyme called the active site.

-For a substrate to bind to the active site of an enzyme it must fit in the active site and be chemically attracted to it. The shape of an enzyme determines how it works. Enzymes have active sites that substrate molecules (the substances involved in the chemical reaction) fit into when a reaction happens.

What is the mass of water that results from combining 2.0 g of hydrogen with 16.0 g of oxygen?
astraxan [27]
The formula for water is H2O so there would have to be two Hyrdogens and one oxygen. Therefore it would be 4g of Hydrogen and 16g of Oxygen leaving you with 20g.
The answer is D.
