After mitosis, it is expected that the daughter cells of a fruit fly with 8 chromosomes should have 8 chromosomes.
MITOSIS:
Mitosis is the kind of cell division in which a single cell produces two daughter cells that are genetically identical to the parent cell. Mitosis results in daughter cells that possess the same number of chromosomes as the parent cell, hence, it is called duplication division. This means that mitotic division maintains the chromosome number of parents in the daughter cells. For example, a fruit fly with 8 chromosomes will produce daughter cells with 8 chromosomes each. Therefore, after mitosis, it is expected that the daughter cells of a fruit fly with 8 chromosomes should have 8 chromosomes.Learn more at: https://brainly.com/question/3327479?referrer=searchResults

Iron (II) Bromide contains one iron atom and two Bromine atoms. Replacing the anion
with oxygen would require more or less oxygen atoms? Why?
Answer:
Atoms are electrically neutral because the number of protons, which carry a 1+ charge, in the nucleus of an atom is equal to the number of electrons, which carry a 1- charge, in the atom. The result is that the total positive charge of the protons cancels out the total negative charge of the electrons so that the net charge of the atom is zero. Most atoms, however, can either gain or lose electrons; when they do so, the number of electrons becomes different from the number of protons in the nucleus. The resulting charged species is called an ion.
Cations and anions
When a neutral atom loses one or more electrons, the total number of electrons decreases while the number of protons in the nucleus remains the same. The result is that the atom becomes a cation—an ion with a net positive charge.
The opposite process can also occur. When a neutral atom gains one or more electrons, the number of electrons increases while the number of protons in the nucleus remains the same. The result is that the atom becomes an anion—an ion with a net negative charge. We can illustrate this by examining some very simple cations and anions, those formed when a single hydrogen atom loses or gains an electron.
Note: Hydrogen is actually somewhat unusual in that it readily forms both cations and anions. Most elements much prefer to form only one or the other. In terms of its electron configuration, can you explain why hydrogen can form both cations and anions? Feel free to post in the comments at the end of the article!

What volume (in L) of carbon dioxide will
be produced from the reaction of 11.8L
of ethane (C2Ho)?
2C2H6(g) + 702(g) + 4CO2(g) + 6H2O(g)
The volume of carbon dioxide produced from 11.8 L ethane at STP is 22.4 L.
What is STP?The STP can be given as the standard temperature and pressure. The standard temperature is 25° C and 1 atm.
It is known that, 22.4 L of gas at STP is equivalent to 1 mole.
Thereby, concentration of ethane is:
22.4 L = 1 mole
11.8 L = 1/22.4 * 11.8 moles
11.8 L = 0.5 moles
From the balanced chemical equation:
2 moles ethane produce = 4 moles carbon dioxide
0.5 moles ethane produce = 4/ 2* 0.5 moles carbon dioxide
0.5 moles ethane produce = 1 moles carbon dioxide
The volume of 1 mole of gas at STP is 22.4 L. Therefore, 11.8 L ethane produces 22.4 L carbon dioxide.

Answer:
ions
Explanation:
When an atom gains or loses an electron, it becomes an ion. Ions formed by the loss of an electron have a positive charge, and those formed by gaining an electron have a negative charge. Positive ions are called cations, and negative ions are called anions. Cations and anions are attracted to each other.

Answer:
The correct option is D
Explanation:
The major raw material used in making cement clinker is limestone. This limestone is usually mixed and heated with clay and can sometimes be mixed, in addition to the clay, with fly ash, black ash, bauxite, iron ore and gypsum. However, the product cement clinker contains different calcium silicates and/or aluminates such as Ca₃SiO₅, Ca₃Al₂O₆, Ca₂(Al,Fe)₂O₅ and Ca₂SiO₄. Thus, the correct option is D.

As the elements in Period 2 are considered in order from lithium to fluorine, there is an increase in the effective nuclear charge and increase in the ionization enthalpy.
What is effective nuclear charge?Effective nuclear charge of an atom is the attraction force of positive charge of protons present inside the nucleus acts as an valence electrons.
The effective nuclear charge is alway slower than the total number of protons of the nucleus because of shielding effect. Where Z is the atomic number and S is the number of shielding electrons.
Therefore, the elements in Period 2 are considered in order from lithium to fluorine, there is an increase in the effective nuclear charge and increase in the ionization enthalpy.

Which statement about quantum numbers is NOT
correct?
a
Two or more electrons in an atom can
have the same set of quantum numbers.
b
Quantum numbers describe the orbitals
of an atom.
с
Quantum numbers describe the location
of each electron in an atom.
d
Quantum numbers describe the energy
of each electron in an atom.
The statement that is not correct here is two or more electrons in an atom can have the same set of quantum numbers. The correct option is a.
What are quantum numbers?To describe the location of an electron in an associated atom, we use a series of specific numbers known as quantum numbers.
Quantum numbers describe the properties of atomic orbitals and the electrons within them. The state of an electron in an atom or ion is described by four quantum numbers.
The primary quantum number, denoted by n, represents the electron's primary energy level. Energy levels are fixed distances from an atom's nucleus.
According to the Pauli Exclusion Principle, no two electrons in an atom or molecule can have the same four electronic quantum numbers.
Because an orbital can only hold a maximum of two electrons, the electrons must have opposing spins.
Thus, the correct option is A.
