Telophase because it is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.

How does a balanced chemical equation demonstrate conservation of mass?
Answer:
A balanced chemical equation will demonstrate the law of conservation of mass because the amount of elements on one side (reactants) will equal the amount of elements on the other side (products).

Reactants:
1 C
4 H

Number of neutrons :
Argon=22
Boron=6
Further explanationThere are two components that accompany an element, the mass number and atomic number
Atoms are composed of 3 types of basic particles (subatomic particles): protons, electrons, and neutrons
The Atomic Number (Z) indicates the number of protons and electrons in an atom of an element.
Atomic number = number of protons = number of electrons ⇒ neutral number
Atomic mass is the sum of protons and neutrons
Atomic Number (Z) = Atomic mass (A) - Number of Neutrons
Argon has an atomic number of 18 and a mass number of 39,948
number of neutrons =
[tex]\tt 39.948-18=21,948\approx 22[/tex]
Boron has an atomic number of 5 and a mass number of 10,811
number of neutrons =
[tex]\tt 10.811-5=5.811\approx 6[/tex]

Cobalt-60 has a half-life of 5.3 years. A sample measures 0.95g of cobalt-
60. If the sample originally had 5.2g of colbalt-60, determine its age in
years or the time elapsed in years. Round up answer in the nearest whole
number and no additional text or unit. *
Answer:
13 years
Explanation:
From;
0.693/t1/2 = 2.303/t log (No/N)
Where;
t1/12 = half-life of Cobalt-60 = 5.3 years
t = time taken = the unknown
No = mass of radioactive material originally present = 5.2 g
N = mass of radioactive material at time t = 0.95 g
Substituting values;
0.693/5.3 = 2.303/t log (5.2/0.95)
0.131 = 2.303/t(0.738)
0.131 = 1.6996/t
t = 1.6996/0.131
t = 12.97 years
t = 13 years(to the nearest whole number)
Isopentyl acetate is the molecule largely responsible for the aroma and taste of bananas. It is made up of carbon, hydrogen, and oxygen. Combustion of a 3.256-g sample of isopentyl acetate produces 7.706 g CO2 and 3.156 g H2O. Using these results, what is the correct empirical formula for isopentyl acetate?
Answer:
Explanation:
7.706 g of CO₂ will contain 12 x 7.706 / 44 g of C
= 2.1 g of C .
This will be contained in 3.256 g of isopentyl acetate
3.156 g of H₂O will contain 2 x 3.156 / 18 g of H
= .351 g of H
This will be contained in 3.256 g of isopentyl acetate
Rest will be oxygen
amount of oxygen in 3.256 g of isopentyl acetate
= 3.256 - ( 2.1 + .351 )
= .805 g
ratio of C , H , O in isopentyl acetate
= 2.1 g : .351 g : .805 g
2.1 / 12 : .351 / 1 : 0.805 / 16 ratio of moles
= .175 : .351 : .05 ratio of moles
= 3.5 : 7.02: 1
= 7 : 14 : 2
empirical formula of isopentyl acetate
= C₇ H₁₄ O₂ .
Meiosis occurs in
embryo cells
plant cells
reproductive cells
animal cell
Answer:
Meiosis is a type of cell division - like mitosis, but it results in four haploid cells with one-half the number of chromosomes as the original diploid cell. Meiosis occurs in plants only during sexual reproduction in specialized cells to produce a haploid egg cell.
Answer:
reproductive cells!
Explanation:
source: oddesyware:"So,how are egg and sperm cells created? The process of cell division in REPRODUCTIVE CELLS IS CALLED MEIOSIS." Hope this helps!
Tendency of an object to float
Answer:
Buoyancy is the ability or tendency of an object to float in a fluid: a liquid or a gas. This happens because fluid pressure increases with depth. According to Archimedes' Principle, the buoyant force on a submerged object is equal to the weight of the liquid displaced by the object.

1 Select the correct answer! Which statement best explains the octet rule? A. Atoms gain, lose, or share electrons to achieve a full valence shell. D B. Compounds always consist of eight electrons. oa. |||||Molecules always consist of eight atoms. OD. All atoms require eight electrons to form bonds. Reset Next Entum. All rights reserved.
Answer:
A. Atoms gain, lose, or share electrons to achieve a full valence shell
Explanation:
The octet rule is best explained as the process in which atoms lose or gain or share electrons to achieve a full valence shell.
In this process bonds are formed when there is an attraction between the two substances. For electrovalent compounds, an atom will lose electrons or gain electron to form an ion, the electrostatic attraction causes the bond formation. Covalent compounds, form by sharing of electrons.Therefore, the octet rule is attained when atoms gain full valence configuration.

A Student notes that a chunk of wood is much lighter after it has been burned. He concludes that burning a substance destroyed some of the mass in that substance. Doi you agree or disagree explain why or why not.
Answer:
No.
Explanation:
When mass is destroyed, it has to have been transformed into something else. Otherwise that would violate the Law of Conversion of Mass. In this case, the wood converted some of its mass in chemical energy to thermal (or heat) energy.

Write the general formula of an alkane and use this to predict the 97th member
of the alkane series.
Explanation:
The general formula of an alkane is given as;
CₙH₂ₙ₊₂
n is the number of the member;
For the 97th member in the series;
n = 97;
2n + 2 = 2(97) + 2 = 196
So, the 97th member is;
C₉₇H₁₉₆
This is how to apply the formula of alkanes which are saturated hydrocarbons to find any member of the series.

To what pressure must a gas be compressed in order to get into a 3.00 cubic foot
tank the entire weight of a gas that occupies 400.0 cu. ft. at standard pressure?
Answer:
133.3atm
Explanation:
Given parameters:
Initial volume = 400ft³
Final volume = 3ft³
Initial pressure = 1atm
Unknown:
Final pressure = ?
Solution:
To solve this problem, we apply Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".
Mathematically;
P₁V₁ = P₂V₂
P and V are pressure and volume
1 and 2 are initial and final states;
Insert parameters and solve;
1 x 400 = P₂ x 3
P₂ = 133.3atm
