18.2L of gas at 95°C and 760 torr is placed in a 15L container at 80 degrees * C ; what is the new pressure ?
romanna [79]

Answer:

884.56 torr

Explanation:

Formula: \frac{P_{1}V_{1} }{T_{1}} = \frac{P_{2}V_{2} }{T_{2}}

P = Pressure

V = Volume

T = Temperature in kelvin (Celsius + 273.15)

\frac{(760)(18.2) }{368.15} = \frac{P(15) }{353.15}

P = \frac{(760)(18.2)(353.15) }{(368.15)(15)}

P = 884.56169

Hi everyone can anyone help with this, the question and diagram is in the pic thx!
seraphim [82]

Answer:

QP

Explanation:

P has 9 electrons.

Electronic Configuration : 2, 7

Valence electrons : 7

P needs 1 electron to get stable electronic configuration.

Q has 3 electrons.

Electronic Configuration : 2, 1

Valence electrons : 1

P needs to loose 1 electron to get stable electronic configuration.

Q donates 1 electron,

Q -----> Q+ + 1 e-

P gains 1 electron,

P + 1 e- -----> P-

Q+ + P- -----> QP

This is an ionic compound.

DNA transcription-to-translation # 1 Homework Unanswered Due in 4 days Given the following sequence of the coding strand, writte
uysha [10]

Explanation:

Translation is the process by which a polypeptide is polymerized from genetic information.

Firstly we have to make a transcription from the coding DNA strand to a single RNA strand (mRNA). RNA pol reads from 5' to 3' of the template strand and nucleotides are added by complementarity ( Adenine with Uracil, Thymine with Adenine and Cytosine with Guanine, Guanine with Cytosine).

DNA:  5'-  CGTTATGTGGACTCTCTGGTATGACTCACCTTAT -3'

mRNA: 5'-GCAAUACACCUGAGAGACCAUACUGAGUGGAAUA -3'

mRNA goes to the ribosomes where translation takes place. The enzyme will read every three letters (codon) starting at the start codon sequence (TAC in DNA, AUG in mRNA). According to codons tRNA carrying the amino acids will place it (by complementary to their anticodon) and the enzyme will join it to the nascent polypeptide or protein.

In order to do this we need to look up the genetic code and assign the proper amino acids.

Unfortunately the given strand does not have a start codon TAC codifying for initial methionine.
