Answer:

The estimate is N  =  1936

Explanation:

From the question we are told that

The molecular weight of the protein is MW_p    =   213 kD   =  213 *10^{3} \  D

Generally the average molecular weight of amino acid is MW_a  =   110 \ D

Generally the number of amino acids in the protein is mathematically represented as

N  = \frac{MW_p}{MW_a}

         N  = \frac}{213 *10^{3}{110}

=> N  =  1936

goldenfox [79]

Answer:

It's a solid.

Explanation:

Solids never change their shape as opposed to gases and liquids. This is because their molecules are tightly packed together. Since all solids have a definite shape, it's volume will also be definite.

How much heat (in kj) is evolved in converting 1.00 mol of steam at 130.0 ∘c to ice at -55.0 ∘c? the heat capacity of steam is 2
nevsk [136]

The heat will be evolved in following process:

1) cooling steam from 130^{0}C to 100^{0}C = Q1

2) conversion of steam to water =Q2

3) Cooling of water to 0^{0}C[/tex=Q3]4) conversion of water to ice=Q45) cooling of ice from [tex]0^{0}C to -55^{0}C=Q5

Let us calculate each energy one by one:

1) Q1:

Mass of water vapour = moles X molar mass = 1mol X 18 = 18 grams

heat capacity of steam is 2.01\frac{J}{g^{0}C }

Q_{1}=massXheat capacityXchangeintemperature=18X2.01X(130-100)=-1085.4J

2) Q2:

for this we need heat of vaporisation of water = -40.7kJ/mol

so the heat evolved in conversion of stem to water is -40.7kJ

3) Q3

the specific heat of water is 4.18\frac{J}{g^{0}C }

heat evolved in cooling of water will be Q_{3}=massXspecific.heatXchange.in.temperature=18X4.184X100=7531.2J=7.531kJ

4)Q4:

The heat of conversion of ice to water (melting) is 6.02kJ/mol

5) Q5

The cooling of ice will require

Q_{5}=massXspecificheatXchangeintemperature=18X2.09X(-55)=-2069.1J=-2.069kJ

The total energy released is

Q_{total}=Q1+Q2+Q3+Q4+Q5=1.085+40.7+7.531+6.02+2.069=59.474kJ

The heat released will be 59.474 kJ
