A mixture of propane and butane is fed into a furnace where it is mixed with air. the furnace exhaust leaves the furnace at 305°

c, 763.0 mmhg and contains only n2, o2, co2, and h2o. the partial pressure of o2 in the exhaust is 100.7 mmhg and the partial pressure of co2 in the exhaust is 33.57 mmhg.

In this item, I supposed, that we are determine the molar fraction of oxygen and carbon dioxide in the sample. This can be done by dividing their respective partial pressures by the total pressure of the sample.

   O2 : mole fraction = (100.7 mmHg) / (763.00 mmHg)  = 0.13

   CO2 : mole fraction = (33.57 mmHg) / (763.00 mmHg) = 0.044

Answers: O2 = 0.13
               CO2 = 0.044

How many moles are in 25 g KMnO4
Ronch [10]

Answer:

0.158 moles KMnO4

Explanation:

According to the Periodic Table,

K = 39.10 g/mol

Mn = 54.94 g/mol

O = 16.00 g/mol

KMnO4 = 39.10 g/mol + 54.94 g/mol + 4(16.00 g/mol) = 158.04 g/mol

25.0 grams KMnO4              1 mole

-----------------------------  x --------------------------  = 0.158 moles KMnO4

                                          158.04 grams

Use a Punnett square. In rabbits, black fur is dominant over white fur. What percentage of offspring will be white if a heterozy
blsea [12.9K]
<h2>Answer 1:</h2>

Option D is correct: 0%

Percentage of offspring will be 0% white if a heterozygous male and homozygous dominant female have offspring.

<h2>Answer 2:</h2>

Option A is correct: 75%

Two parents who are heterozygous are expecting a child. the percentage that the child will have free ear lobes will be 75%.

<h2>Answer 3:</h2>

Option A is correct: 25%

Two parents who are heterozygous are expecting a child. 25 is the percentage that the child be homozygous dominant.

<h2>Answer 4:</h2>

Option D is correct: 25%

If a homozyous recessive and a heterozygous plant have offspring. 25 will percentage will have smooth seeds.

<h2>Answer 5:</h2>

Option D is correct: 0%

If a homozyous recessive and a heterozygous plant have offspring. There will 0% chances that offsprings will be homozygous dominant.

<h2>Answer 6:</h2>

Option D is correct: substitution

In this question one of base thymine at 7 number is substituted with another base Adenine.

<h2>Answer 7:</h2>

Option A is correct: Incomplete dominance

Incomplete dominance is a form of intermediate inheritance in which one allele for a specific trait is not completely expressed over its paired allele. This results in a third phenotype in which the expressed physical trait is a combination of the phenotypes of both alleles.

<h2>Answer 8:</h2>

Option A is correct: T T C G A A T C T G T A T G A C

After the insertion of a new base thymine the new sequence will be of option A.

<h2>Answer 9:</h2>

True

Yes this is true that "Environmental influences and genetics can determine a person's phenotype".

<h2>Answer 10:</h2>

Option B is correct: selective breeding

Humans have been choosing desired traits of livestock and pets for centuries by breeding organisms that they choose with the traits they desire. This process is called selective breeding.

<h2>Answer 11:</h2>

homologous chromosomes

karyotyping is a test that evaluates the number and structure of a person's chromosomes in order to detect abnormalities. Chromosomes are thread-like structures within each cell nucleus and contain the body's genetic blueprint.
