Given what we know, we can confirm that the term used to describe an offspring that possesses the same trait for both genes is homzygous.
What does it mean to be homzygous?This is as indicated in the question, it refers to organisms that have inherited the same allele for a gene from both parents. Meaning that both variations of said gene in this individual are the same and therefore, there is no possibility of a distinct expression.
Therefore, we can confirm that the term used to describe an offspring when it possesses the same trait for both genes is homzygous.

Using the formula M1V1 = M2V2 , how many milliliters of a 2.50 M hydrochloric acid solution is required to make 100.0 mL of a 0.750 M solution?
30mL
1.88
300mL
333mL
Answer:
30mL is required
30ml of a 2.50 M hydrochloric acid solution is required to make 100.0 mL of a 0.750 M solution.
What is HCl?HCl is an acid which is made up of hydrogen and chlorine gas.
By the formula of dilution
M1V1 = M2V2
where V1 = 2.50 m
M2 = 100.0
V2 = 0.750 m
M1 × 2.50 m = 100.0 × 0.750 m
M1 = 30 ml
Thus, the M1 is 30 ml option a is correct.

12. Why does a water molecule have a bent shape?
A. The protons in the nucleus of the hydrogen atoms repel the protons in the nucleus of the oxygen
atom.
B. The oxygen atom has lone pairs of
electrons.
C. The hydrogen atoms repel each other.
D. It has two covalent bonds.
Answer:
A water molecule consists of two hydrogen atoms bonded to an oxygen atom, and its overall structure is bent. This is because the oxygen atom, in addition to forming bonds with the hydrogen atoms, also carries two pairs of unshared electrons. All of the electron pairs—shared and unshared—repel each other.

Why do you feel the force of Earth's gravity?
•Why do you feel the force of Earth's gravity?
Answer:
•Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. That's what gives you weight. And if you were on a planet with less mass than Earth, you would weigh less than you do here.

1.) Given the % composition of each element in the following compound. Calculate and determine the empirical formula. Name the formula as well.
1.6% H 22.2% N 76.2% O.
Hint, assume a 100 g sample, then you will have 1.6 g H, 22.2 g N and 76.2 g O
2. A sample of a compound is broken down into its constituent elements and yields 13.0 g of lead, 1.77 g of nitrogen and 4.03 g of oxygen. What is the empirical formula for this compound?
3.) If 4.04g of N combine with 11.46g O to produce a compound with a molar mass of 108.0 g/mol, what is the molecular formula of this compound?
1. The empirical formula of the compound is HNO₃. The name of the compound is trioxonitrate (v)
2. The empirical formula of the compound is PbN₂O₄ or Pb(NO₂)₂
3. The molecular formula of the compound is N₂O₅
1. How to determine the empirical formula Hydrogen (H) = 1.6 gNitrogen (N) = 22.2 gOxygen (O) = 76.2 gEmpirical formula =?Divide by their molar mass
H = 1.6 / 1 = 1.6
N = 22.2 / 14 = 1.586
O = 76.2 / 16 = 4.7625
Divide by the smallest
H = 1.6 / 1.586 = 1
N = 1.586 / 1.586 = 1
O = 4.7625 / 1.586 = 3
Thus, the empirical formula of the compound is HNO₃ and the name of the compound is trioxonitrate (v)
2. How to determine the empirical formula Lead (Pb) = 13 gNitrogen (N) = 1.77 gOxygen (O) = 4.03 gEmpirical formula =?Divide by their molar mass
Pb =13 / 207 = 0.0628
N = 1.77 / 14 = 0.1264
O = 4.03 / 16 = 0.2519
Divide by the smallest
Pb = 0.0628 / 0.0628 = 1
N = 0.1264 / 0.0628 = 2
O = 0.2519 / 0.0628 = 4
Thus, the empirical formula of the compound is PbN₂O₄ or Pb(NO₂)₂
3. How to determine the molecular formulaWe'll begin by determining the empirical formula of the compound. This can be obtained as follow:
Nitrogen (N) = 4.04 gOxygen (O) = 11.46 gEmpirical formula =?Divide by their molar mass
N = 4.04 / 14 = 0.2886
O = 11.46 / 16 = 0.71625
Divide by the smallest
N = 0.2886 / 0.2886 = 1
O = 0.71625 / 0.2886 = 2.5
Multiply by 2 to express in whole number
N = 1 × 2 = 2
O = 2.5 × 2 = 5
Thus, the empirical formula of the compound is N₂O₅
Finally, we shall determine the molecular formula of the compound. This can be obtained as follow:
Empirical formula = N₂O₅Molar mass of compound = 108 g/mol Molecular formula =?Molecular formula = empirical × n = molar mass
[N₂O₅]n = 108
[(2×14) + (16×5]n = 108
[28 + 80]n = 108
108n = 108
Divide both side by 108
n = 108 / 108
n = 1
Molecular formula = [N₂O₅]n
Molecular formula = [N₂O₅] × 1
Molecular formula = N₂O₅

Explanation:
Compare the location of bonding electrons in a polar covalent bond with those in a nonpolar covalent bond!!?????!????? I NEED HELPPPP
Answer:
A polar covalent bond will have the electrons shifted more towards one side or the other; a nonpolar bond will have evenly distributed electrons.
Explanation:
The basis for a polar bond is that the electrons are shared unevenly. Some elements are more electronegative than others; that is, they pull harder on the electrons and tend to have more electrons around them. Following the periodic trends, Fluorine is the most electronegative element, so it will likely have the most dense area of electrons in a molecule. All this means that in a polar molecule, the electrons will be spread out unevenly along the lengths of the bonds as some elements will pull on them more than others will.
Nonpolar molecules do not have to worry about differences in electronegativity, and so the electron density will be pretty evenly distributed along the entire molecule.

A blue fish and a yellow fish mate and have green offspring. What type of inheritance is this an example of?
The type of inheritance displayed by the illustration is incomplete dominance.
Incomplete dominanceIt is a kind of inheritance in which one of the two alleles of a gene exerts incomplete influence on the other allele.
For example, a cross of white and red flower plants yielding a plant with pink flowers. It means that the dominance of the red or pink allele is incomplete.
The same is applicable to a blue fish mating with a yellow fish to produce green offspring. A blend of the two colors occurred.

Distillation:
is the process in which we separate two liquids on the basis of their difference in boiling points.How it works:
Since chloroform has less boiling point, it will evaporate and collected first and benzene will follow it after sometime.

Why is it important to balance the redox equation for the electrolysis of water?.
Electrolysis is a process, which allows us to break down a chemical compound into its elements, completing the balance by adjusting the number of atoms on both sides of the reaction is important because the number of electrons given up during oxidation must be the same as the number of electrons gained during the reduction.
What is electrolysis of water?It is a process of oxidation and reduction of one or more elements that, through the induction of electric current, breaks down the water molecule (H2O), thus producing gaseous hydrogen and oxygen.
Oxidation and reduction processes occur simultaneously and never in isolation, which is why they are called redox reactions.
Therefore, we can conclude that electrolysis is a process where electrical energy will change to chemical energy where it is important that the number of electrons given up during oxidation is the same as the number of electrons gained during reduction.

a maximum a person on earth can lift is about 270kg. On mars a person could lift is about 440kg. Explain why?
The discrepancy in how much a person can lift on Earth and in Mars is due to the difference in the acceleration due to gravity in both planets.
Dependence of Weight on the Acceleration due to GravityAlthough, the physical Quantity, mass is always constant as it is a measure of the quantity of matter in a body. The weight on the other hand is a function of the acceleration due to gravity and hence is different in different planets.
