Answer:

The pH of a solution is simply a measure of the concentration of hydrogen ions,  

H

+

, which you'll often see referred to as hydronium cations,  

H

3

O

+

.

More specifically, the pH of the solution is calculated using the negative log base  

10

of the concentration of the hydronium cations.

Now, we use the negative log base  

10

because the concentration of hydronium cations is usually significantly smaller than  

1

.

As you know, every increase in the value of a log function corresponds to one order of magnitude.

. How many grams of Na2SO4 are required to make 2700 mL of a 2.0 M solution?
ratelena [41]

Answer:

Explanation:

From the net ionic equation

Ba2+(aq) + SO42-(aq) ==> BaSO4(s) we see that 1 mole Ba2+ reacts with 1 mole SO42- to -> 1 mol BaSO4

Find moles of Ba2+ used: 0.250 moles/L x 0.0323 L = 0.008075 moles Ba2+

Find moles SO42- present: 0.008075 moles Ba2+ x 1 mol SO42-/1 mol Ba2+ = 0.008075 mol SO42-

Find mass of Na2SO4 present: 0.008075 mol SO42- x 1 mol Na2SO4/1 mol SO42- x 142.04 Na2SO4/mole = 1.14698 g = 1.15 g Na2SO4 (to 3 significant figures)

C12H22011+1202-->12CO2+11H20
kogti [31]

Answer:

0.185moles

Explanation:

Given parameters:

Volume of O₂  = 49.8L

Unknown:

Number of moles of sucrose required  = ?

Solution:

We can assume that the reaction takes place at standard temperature and pressure.

From this, we can find the number of moles of oxygen that reacted and extrapolate to that of sucrose.

Chemical equation;

           C₁₂H₂₂0₁₁  +  120₂   →   12CO₂   +   11H₂0

Number moles  = \frac{volume of gas}{22.4}   at STP

Number of moles of oxygen gas = \frac{49.8}{22.4}   = 2.22moles

           12 moles of oxygen gas combines with  1 mole of sucrose

       2.22 moles of oxygen gas will combine with \frac{2.22}{12}   = 0.185moles

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.
