A gas has a volume of 62.65 L at STP. At what temperature (in oC) would the volume of the gas be 78.31 L at a pressure of 612.0

masha68 [24]

Answer:

1.788 C DEGREES

Explanation:

STP is 1 atm at 273.15 K

P1V1/T1 = P2V2/T2

(1)(62.65) / (273.15) = (612/760)(78.31)/T2

T2 = 274.93 K = 1.788 C

The turnover number is defined as the maximum number of substrate molecules that can be converted into product molecules per uni

hjlf

Answer:

Turnover number = 113182s⁻¹

Explanation:

Turnover number is a concept used to know the activity of an enzyme. The higher turnover number, the higher activity of the enzime.

Turnover number is defined as:

Turnover number = Rmax / [E]t

As Rmax is 249 μmol⋅L⁻¹⋅s⁻¹ and [E]t is 2.20 nmol⋅L⁻¹

As 1μmol = 1000nmol, Rmax = 249000 nmol⋅L⁻¹⋅s⁻¹. Replacing:

Turnover number = 249000 nmol⋅L⁻¹⋅s⁻¹ / 2.20 nmol⋅L⁻¹

<h3>Turnover number = 113182s⁻¹</h3>

I don't know how to transcribe the following DNA sequecne too rna

Llana [10]

Answer:

There is only one change when transcribing from a DNA sequence to a RNA sequence.

Explanation:

The change when transcribing is that instead of thymine (T) in a DNA sequence, you have Uracil (U) in a RNA sequence. The rest will stay the same. So, DNA has ATCG, whereas RNA has UACG. There should be NO thymine (T) in your RNA sequence–– it should only include the four of the following: UACG.

[FORMAT]: DNA is to RNA

A is to U (IMPORTANT, NO "T") –– Think as Apples Under the Tree

T is to A –– Think as Trees have Apples

C is to G –– Think as Car in the Garage

G is to C –– Think as Inside the Garage are Cars
