The letter R indicates round seeds that are dominant over the wrinkled variety, represented by r. Create a Punnett square by selecting the genetic makeup of the parents. You can make the parents both homozygous, both heterozygous, or a combination. Show the possible outcomes of the traits in their offspring.
Answers
Answer and Explanation:
Let's just make it easy and have both parents be heterozygous. This means that they each have 1 dominant allele (R) and 1 recessive allele (r). Make a Punnett Square (see attachment).
The possible outcomes are RR (one of it), Rr (two of it), and rr (one of it). That means that phenotypically, 3 of the offspring will be round and 1 will be wrinkled.
Answer:
Rr, RR, rr

What is the volume of a 0.120 M solution that contains 9.35 g of HCI?
Answers
Answer:
2.13L
Explanation:
first you must find the amount(mols) of HCl in the solution. then you can use that to find the volume of the solution.
we know the:
mass m = 9.35g
molar mass M = 1 + 35.5=36.5 g/mol ( check periodic table )
concentration c = 0.120 mol/L
amount ( mols) of HCl:
n= m/M
n(HCl) = 9.35/36.5
= 0.2561644 mol
concentration of HCl in solution:
n= cV
V(HCl) = n/c
= 0.2561644/0.120
= 2.1347
= 2.13 L (3sf)
Final answer:
To find the volume of the solution, we can use the equation C₁V₁ = C₂V₂, where C₁ and V₁ are the concentration and volume of the stock solution, and C₂ and V₂ are the desired concentration and volume of the diluted solution.
Explanation:
To find the volume of the solution, we can use the equation:
C₁V₁ = C₂V₂
Where C₁ and V₁ are the concentration and volume of the stock solution, and C₂ and V₂ are the desired concentration and volume of the diluted solution. Rearranging the equation to find V₂:
V₂ = (C₁V₁) / C₂
Plugging in the given values, we have:
V₂ = (0.120 M * V₁) / 0.120 M
V₂ = V₁
a gas has a volume of 6 liters and a pressure of 1.5 atm. if the container is compressed to a volume of 2 liters, what will the pressure of the gas be?
Answers
Answer:
The pressure will be 4, 5 atm
Explanation:
We use Boyle Mariotte's formula: for a given mass of gas at constant temperature, the pressure and volume vary inversely proportionally:
P1xV1=P2xV2
P2= (P1xV1)/V2 = (1,5 atm x 6 L)/2 L=4,5 atm

iron, Fe?
Answers
Answer:
126g
Explanation:
Data obtained from the question include:
Mole of Fe = 2.5moles
Molar Mass of Fe = 56g/mol
Mass of Fe =?
Number of mole = Mass/Molar Mass
Mass = number of mole x molar Mass
Mass of Fe = 2.25 x 56
Mass of Fe = 126g
Therefore, the mass in 2.25mol of Fe is 126g
Answer: 126g
Explanation:
No of moles = mass given/molar mass
No of moles given=2.25mol
Molar mass of Fe= 56
Mass =?
Substitute the values into the formula
No of moles = mass given/molar mass
2.25= mass/56
Mass= 56×2.25
Mass = 126g
Mass of Fe in 2.25mols is 126g
Calculate the (H+), and indicate whether it is an acid, base, or neutral for a
solution with a concentration of [OH-] = 8.8 x 10^-9 M.*
Answers
Answer:
As the pH value is less than 7, (in this case 5,94) it corresponds to an acidic substance.
Explanation:
The pH indicates the acidity or basicity of a substance. pH values between 0 and less than 7 indicate acidic solutions, 7 neutral and higher than 7 to 14 basic. It is calculated as: pH = -log (H 30+)
First we calculate the concentration of H 30+:
Both pH and pOH have a relationship to belonging to the same aqueous solution: the expression of the Kwater (ionic product of the water Kw) is used:
(H3O +) x (OH -) = 1x10 ^ -14
(H3O +) x (8.8 x 10^-9)= 1x10 ^ -14
(H30+)= 1x10 ^ -14/(8.8 x 10^-9)
(H30+)= 1,14 x 10^-6 M
pH= -log (H30+)
pH= -log (1,14 x 10^-6)
pH=5,94 As the pH value is less than 7, it corresponds to an acidic substance.
What is the Molarity of the Sulfate ion in a 2M K2SO4 solution?
Answers
Answer: The Molarity of the sulphate ion in a 2M [tex]K_2SO_4[/tex] solution is 2M
Explanation:
Molarity is defined as the number of moles of solute dissolved per liter of the solution.
[tex]Molarity=\frac{n\times 1000}{V_s}[/tex]
where,
n= moles of solute
[tex]V_s[/tex] = volume of solution in ml
[tex]K_2SO_4\rightarrow 2K^{+}+SO_4^{2-}[/tex]
Now as 1 mole of [tex]K_2SO_4[/tex] gives = 1 mole of [tex]SO_4^{2-}[/tex]
2 moles of [tex]K_2SO_4[/tex] gives =[tex]\frac{1}{1}\times 2=2[/tex] moles of [tex]SO_4^{2-}[/tex]
Thus Molarity of the sulphate ion in a 2M [tex]K_2SO_4[/tex] solution is 2 M

Answers
Answer:
endothermic reaction.
Explanation:
An increase in the temperature of a system at equilibrium favors the backward or reversible reaction.
What is equilibrium law?According to the equilibrium law, when any external stress is applied at the equilibrium state then the equilibrium will shift to that side which decreases the external affect.
Suppose a chemical reaction which is exothermic in nature will be represented as:
A + B ⇄ C + D
If we increases the temperature then reaction will shift to the left side to overcome the effect of increased temperature.
Hence reversible reaction proceeds on increasing the temperature.

Determine the molarity of a solution prepared by dissolving 141.6 g of citric acid, C3H5O(COOH)3, in 3500.0 mL of water ?
Answers
Answer:
0.21M of C3H5O(COOH)3
Explanation:
Molarity = no of mole/ volume of solution
Molar mass of C3H5O (COOH)3 = 192.12g
No of mole of C3H5O (COOH)3 = 141.6/192.12 = 0.74mol
1000mL = 1L
3500mL = 3.5L
Molarity = 0.74/ 3.5 = 0.21M of C3H5O (COOH)3
Answer:
0.2M
Explanation:
The molarity of a solution is given by;
M = number of moles / volume
Number of moles = mass/molar mass
Mass of Citric acid = 141.6g
Molar mass of citric acid = (6×12)+(8×1)+(7×16)
= 72+8+112=192g/mol
Number of moles of citric acid=141.6/192=0.74mol
Volume = 3500.0 mL = (3500/1000)L=3.5L
Molarity of the solution = 0.74mol/3.5L=0.2mol/L
Therefore, 0.2mol/L or 0.2M concentration is prepared by dissolving 141.6 g of citric acid, C3H5O(COOH)3, in 3500.0 mL of water

What is the total number of oxygen atoms represented in the formula na2c03.10h2o?
Answers
As per the given chemical formula- Na2CO3.10H2O, one mole of the chemical compound contains 13 moles of oxygen atoms. Hence
Number of moles of oxygen atoms in one mole of Na2CO3.10H2O = 13
number of moles of oxygen atoms in 0.2 moles of Na2CO3.10H2O = 13 X 0.2 = 2.6
Now, one mole of a substance contains 6.022 X 10^23 particles of the substance. Thus
number of atoms of oxygen in one mole of oxygen atom = 6.022 X 10^23
number of moles of oxygen atoms in 2.6 moles of oxygen atoms = 2.6 X 6.022 X 10^23 = 15.657 X 10^23
= 1.566 X 10^24
Thus, there are 1.566 X 10^24 atoms of oxygen in 0.2 moles of Na2CO3.10H2O.
