The most controversial ethical issue surrounding modifying human DNA is, according to the text, is that it will lead to the creation of designer children with improvements in intelligence or physical performance.
What is DNA?Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid.
The DNA of an individual can be found in almost all of their cells.
The majority of DNA is found in the cell nucleus (where it is known as nuclear DNA), but there is also a small quantity of DNA in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Other ethical issues include the possibility of an identity crisis for a person born with genes from three different people as well as the danger of making mistakes in the human genome that could lead to the spread of genetic illnesses in the population.
Thus, it can be concluded that there are various ethical issues of editing human DNA.

D. 2Cl2 + 2NaBr--> Br2 + NaCl2
E. Cl2 + 2NaBr-> Br2 + 2NaCl.
Answer:
E. Cl2 + 2NaBr ----> Br2 + 2NaCl
Explanation:
Number of Cl molecules is 2 on the reactant and product side of the equation.
Number of Na molecules is 2 on the reactant and product side of the equation.
Number of Br molecules is 2 on the reactant and the product side of the equation.
As the reactant side is equal to the product side, the equation is balanced.

Calculemos la formula empirica y molecular de carbonato de hierro Fe2(co3)3.Fe.38.3%C.12.3%.0.4 92% masa 292g
Respuesta:
292 g / mol;
Por favor, consulte la explicación.
Explicación:
El número de átomos de cada elemento en el compuesto: Fe2 (co3) 3.
Fe = 2; C = 3; 0 = 3 * 3 = 9
Fe2 = 112 g / mol
C = 12 g / mol
O = 16 g /
Masa molecular = ((112 + (12 * 3) + (16 * 9)
= (112 + 36 + 144)
= 292 g / mol.
Total = 2 + 3 + 9 = 14
Fe2 = 112/292 * 100% = 38,356%
C = 36/292 * 100% = 12,328 * '
O = (16 * 9) / 292 * 100% = 49,32%
The pressure in a tire is 101 kPa at 10.0°C, what will be the pressure of a tire at 45.0°C?
Answer:
P₂ = 113.49 kPa
Explanation:
Given that,
Initial pressure, P₁ = 101 kPa
Initial temperature, T₁ = 10.0°C = 283 K
Final temperature, T₂ = 45°C = 318 K
The relation between pressure and temperature is given by :
[tex]\dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}[/tex]
Where
P₂ is the new pressure
So,
[tex]P_2=\dfrac{P_1T_2}{T_1}\\\\P_2=\dfrac{101 \times 318}{283 }\\\\P_2=113.49\ kPa[/tex]
So, the new pressure is equal to 113.49 kPa.

How does snow sometimes appear blue?
Answer: So, why is the snow and ice blue? Similar to water, snow absorbs red and yellow light, leaving blue light behind to give it that bluish appearance. If snow is only a few inches deep, none of the light will be left behind, making the snow appear white. The deeper the snow, the more blue light is left behind.

40 g of NaCl is added to 1500 g of water. What is the molality of the resulting
solution?
Molality = moles of solute/mass (in kg) of solvent
The solute here is NaCl, of which you have 40 g or 40/58.4428 = 0.6844 moles NaCl.
The solvent here is water, of which you have 1500 g or 1.500 kg H2O.
The molality of the resulting solution would thus be 0.6844 moles NaCl/1.500 kg H2O = 0.4562 mol/kg.
If you have to consider sig figs, then your final answer would have one sig fig (40 g has one sig fig). In that case, your final answer would be 0.5 mol/kg.
If you produce 10 g of water in the reaction from 20 g of O2 what is your percent yield? 2H2+O2>2H2O
Answer:
44.4%
Explanation:
The balanced chemical equation for the reaction is:
2 H₂(g) + O₂(g) → 2 H₂O(g)
According to the equation, 1 mol of O₂ produces 2 moles of water (H₂O). We convert the moles to grams by using the molecular weight (Mw) of each compound:
Mw(O₂) = 2 x 16 g/mol O = 32 g/mol
mass O₂ = 1 mol x 32 g/mol = 32 g O₂
Mw(H₂O) = (2 x 1 g/mol H) + 16 g/mol O = 18 g/mol
mass H₂O = 2 mol x 18 g/mol = 36 g H₂O
Thus, from 32 grams of O₂, 36 g of H₂O are produced (stoichiometric ratio= 36 g H₂O/32 g O₂). We calculate the amount of H₂O that would be produced from 20 grams of O₂ by multiplying the stoichiometric ratio by the mass of O₂, as follows:
36 g H₂O/32 g O₂ x 20 g O₂ = 22.5 g H₂O
The theoretical yield of H₂O is 22.5 g, and the actual amount produced is 10 g. So, we calculate the percent yield as follows:
Percent yield = actual yield/ theoretical yield x 100
= (10 g)/(22.5 g) x 100
= 44.4%
Can i titrate a solution of unknown concentration with another solution of unknown concentration and still get a meaningful answer
Answer:
No, I don't think so at least
Explanation:
In chemistry, you do calculations to find the concentration of a solution with another solution of KNOWN concentration. Without concentrations of either solution, were would you get values from? Where would you start? :3
You can not titrate a solution of unknown concentration with another solution of unknown concentration and still get a meaningful answer.
Titration involves the standardization of unknown solution using a standard solution. By this definition, titration must involve a standard solution.
Since the two unknown solutions are not standardized, we can never get a meaningful answer because we can not be able to perform any calculation unless we have a standard solution.

Fluorine-21 has a half life of approximately 12 seconds. What fraction of the original nuclei would remain after 1 minute?
Answer:
The correct answer would be = 1/32.
Explanation:
The half-life is the time required for a quantity to reduce to half of the initial value of an object or element.
it is given that Fluorine-21 has a half-life time = 12 seconds
then in a minute the number of half-lives,
12 seconds = 12/60 of a minute or 1/5 of a minute
This means in 1 minute we will half the sample 5 times.
(1/2)^5 = 1/32 is the fractional remainder
Thus, the correct answer would be 1/32.
What is the molarity of a solution when 2.75 g of NaCl is dissolved in 1100 mL of solution?
0.043 M
0.25 M
0.43 M
4.27 M
Answer:
Explanation:
0.25 M
The molarity of a solution will be 4.27M .
What is molarity?Molarity (M), often known as molar concentration, is the concentration of a solution expressed in moles of solute per liter of solution.
What is solution?Solution can be considered as a mixture of more than one component. It may be homogeneous solution as well as heterogeneous solution.
Gram to mole conversion:
[tex]=\;2.75\;g.\;\frac{1\;mol}{58.44g} \\=\;0.0470 \;mol[/tex]
Molarity of the solution can be calculated by using the following formula:
It is calculated that, moles of solute = 0.0470 mol, volume of the solution = 1100 mL.
Now, put the value of given data in molarity formula:
[tex]Molarity=\frac{Moles\;of\;the\;solute}{Volume \;of\; the\; solution} \\=\frac{0.0470\;mol}{1100 \;mL} \\=\;4.27\;mol/mL\\=\;4.27\; M[/tex]
Therefore, the molarity of a solution will be 4.27M.

Calculate the heat (in calories) released when 115 g of CHCl3 changes from a liquid to a solid at
its freezing point.
Answer: 8855 Joules energy is released when 115 g of [tex]CHCl_3[/tex] changes from a liquid to a solid at its freezing point.
Explanation:
Latent heat of freezing is the amount of heat released to convert 1 mole of liquid to solid at atmospheric pressure.
Amount of heat released to freeze 1 gram of [tex]CHCl_3[/tex] = 77 J/g
Mass of [tex]CHCl_3[/tex] given = 115 gram
Heat released when 1 g of [tex]CHCl_3[/tex] is freezed = 77 J
Thus Heat released when 115 g of [tex]CHCl_3[/tex] is freezed =[tex]\frac{77}{1}\times 115=8855J[/tex]
Thus 8855 Joules energy is released when 115 g of [tex]CHCl_3[/tex] changes from a liquid to a solid at its freezing point.
How many moles are in 297g of nh3?
Please show work, will give brainliest.
Answer:
17.5moles
Explanation:
The number of moles in a substance can be calculated by using the formula;
Number of moles (n) = mass (m) ÷ molar mass (MM)
According to this question, mass of ammonia (NH3) = 297g
Molar Mass of NH3 = 14 + 1(3)
= 17g/mol
n = 297/17
n = 17.47
Number of moles of NH3 = 17.5moles

how many moles is 130g of cocl2
Answer:
1.3142 mol CoCl2
Explanation:
Well, to answer this we need to find out how many grams are in a single mole of CoCl2. Two find that we need to get the molar mass of CoCl2
Co = 28.0101 g Co per mole
Cl = 35.453 * g Cl per mole
28.0101 + 2 * 35.453 = 98.9161 g CoCl2 per mole
Now, we divide:
130/98.9161 = 1.3142 mol CoCl2
There are 1.31 moles in 130grams of cobalt chloride (CoCl2). Details about how to convert mass to moles can be found below.
