Explanation:
Strontium-90 is a byproduct in nuclear reactors fueled by the radioisotope uranium-235. The half-life of strontium-90 is 28.8 yr. What percentage of a strontium-90 sample remains after 115.2 yr?
The half-life of a radioisotope is the amount of time it takes for half of the atoms in a sample to decay. For strontium-90, the half-life is 28.8 years.
To determine the percentage of a sample that remains after 115.2 years, we can use the formula:
Percentage remaining = (1/2)^(time in years / half-life) x 100
Plugging in the values, we get:
Percentage remaining = (1/2)^(115.2 / 28.8) x 100
Percentage remaining = (1/2)^4 x 100
Percentage remaining = (1/16) x 100
Percentage remaining = 6.25%
So, after 115.2 years, 6.25% of a strontium-90 sample remains.

To determine the order of the reaction with respect to reactant A, we can perform experiments at different concentrations of A while keeping the concentration of B constant.
What are reactants?
A reactant is a substance that is consumed in a chemical reaction. In a balanced chemical equation, all reactants are listed on the left side of the equation and are consumed as the reaction proceeds. The reactant that is used up first in a reaction is called the limiting reactant or limiting reagent.
From the data provided, we see that when [A] is 1.5 M and [B] is 1.5 M, the rate of the reaction is 3.2 x 10^-1 M/s. When [A] is 3.0 M and [B] is 1.5 M, the rate of the reaction is 6.4 x 10^-1 M/s.
Since the rate of the reaction is directly proportional to the concentration of A, we can say that the order of the reaction with respect to A is 1.
To determine the order of the reaction with respect to reactant B, we can perform experiments at different concentrations of B while keeping the concentration of A constant. From the data provided, we see that when [A] is 1.5 M and [B] is 1.5 M, the rate of the reaction is 3.2 x 10^-1 M/s. When [A] is 1.5 M and [B] is 2.5 M, the rate of the reaction is 3.2 x 10^-1 M/s.
Since the rate of the reaction does not change with the concentration of B, we can say that the order of the reaction with respect to B is 0.
The overall reaction order is the sum of the order with respect to each reactant. So the overall reaction order for this reaction is 1 + 0 = 1.
Therefore, the order of the reaction with respect to reactant A is 1, the order of the reaction with respect to B is 0, and the overall reaction order is 1.

How many grams of calcium nitride (Ca3N2) are produced when 4.00 g of nitrogen reacts with an excess of calcium?
3Ca + N2 → Ca3N2
a
21.2 g of Ca3N2
b
0.756 g of Ca3N2
c
0.378 g of Ca3N2
The correct answer is c. 0.378 g of Ca3N2
The balanced chemical equation for the reaction is:
3Ca + N2 → Ca3N2
We can see that for every 3 moles of calcium, 1 mole of nitrogen is used. Using the molar mass of calcium (40.08 g/mol) and nitrogen (28.02 g/mol) we can calculate how many moles of each reactant we have.
4.00 g of nitrogen is equal to 4.00 g / 28.02 g/mol = 0.1428 mol of nitrogen
We know that we have an excess of calcium, so we only need to consider the amount of nitrogen present.
We can use the stoichiometry of the reaction to calculate how many grams of Ca3N2 are produced.
1 mole of nitrogen reacts with 3 moles of calcium to produce 1 mole of Ca3N2
0.1428 mol N2 x (1 mole Ca3N2 / 3 mole N2) = 0.04760 mole of Ca3N2
We can convert this number of moles to grams using the molar mass of Ca3N2 (128.09 g/mol)
0.04760 mole of Ca3N2 x 128.09 g/mol = 0.378 g of Ca3N2

The difference between atom a and atom b is that atom b has lost some of its inner electrons.
What is the electrons?
Electrons are subatomic particles that are part of the atomic structure. They carry a negative electrical charge and are found in the shells or orbitals of an atom. Electrons are the fundamental particles of electricity and are responsible for a variety of electrical and magnetic phenomena. These particles are also the main components of electric and magnetic fields. In addition, electrons are the building blocks of atoms, as they are arranged in shells of varying sizes and numbers depending on the element. Electrons are the main constituents of all matter, and they are responsible for the bonds that form between atoms and molecules.
This is because the outer electron of atom b has moved to a higher energy state, which is the 5s orbital, while the outer electron of atom a is in the 3s orbital. This means that atom b has fewer electrons in its inner shells, giving it a different electron arrangement and consequently a different chemical behavior.

Which of the following best describes the expected product of the reaction H3O+below? A) An epoxide B) A secondary alcohol C) A primary alcohol D) A tertiary alcohol
The expected product of the reaction H3O+ is: C) A primary alcohol
H3O+ is a protonated water molecule, also known as a hydronium ion. When an alcohol molecule is treated with H3O+, it can undergo an acid-catalyzed reaction called an "alcohol dehydration" which results in the removal of a molecule of water and the formation of an alkene. The H3O+ acts as an acid, donating a proton (H+) to the alcohol molecule, which results in the formation of an alkyloxonium ion intermediate. This intermediate then loses a molecule of water to form an alkene.The product of the reaction is affected by the type of alcohol that is present in the reaction. In the case of a primary alcohol, it will lose water to form an alkene and a primary alcohol will lose water to form an alkene with one less carbon atom than the alcohol. A secondary alcohol and a tertiary alcohol will lose water differently and will not form an alkene, instead, they will form a carbocation intermediate which is not a stable species and will react further with other reagents to form other products.An epoxide is a cyclic ether and it is not formed from the reaction of an alcohol with H3O+.

A backyard pond has 2.5 M3 of water what is the volume in cubic inches?
The volume in cubic inches 1.5x10^5in3 if A backyard pond has 2.5 M3 of water.
What is volume formula?Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height. How you refer to the different dimensions does not change the calculation: you may, for example, use 'depth' instead of 'height'.
What is volume of a liquid?Measuring the Volume of a Liquid At its most basic level, volume is simply a measure of space. When measuring the volume of a liquid, sometimes referred to as capacity, the units liters (L) and milliliters (mL) are used. Devices used for this measurement include graduated cylinders, beakers, and Erlenmeyer flasks.

aluminum is the element that is best represented by the six successive ionization energies listed because
Because it only needs to lose one electron in order to create the next valence electron shell, the stable 3s shell.
What is an ionization energies?Ionization energy is the least amount of energy required to release the loosely bound electron from an isolated gaseous atom, positive ion, or molecule.Ionization energy is a measure of the difficulty of removing an electron from an atom or ion or the propensity of an atom or ion to give up an electron. Typically, when a chemical species is in its ground state, an electron is lost.The amount of energy required to remove an electron from an atom is referred to as ionization energy. As we move along a group, the ionization energy diminishes.One isolated, gaseous atom in the ground electronic state must absorb a certain amount of energy in order to discharge an electron and produce a cation. This energy is known as the ionization energy. The amount of energy required for each atom in a mole to lose one electron is measured in kJ/mole, or kJ/mol.To learn more about ionization energies refer to:

which of the following best represents how a single gene can encode more than one type of protein? choose 1 answer: choose 1 answer:
Splicing represents how a single gene can encode more than one type of protein.
What is Splicing?
Splicing is the process of removing introns from a gene and joining the exons together. This process is necessary for the production of a functional protein. In eukaryotic organisms, genes are composed of both exons (the coding regions) and introns (non-coding regions). During splicing, the introns are removed and the exons are connected. The resulting mRNA molecule is then ready for translation into a functional protein. Splicing can be either intron-mediated or trans-splicing, depending on the type of organism and the type of gene. Intron-mediated splicing occurs in eukaryotes, while trans-splicing occurs in prokaryotes.
It is a post-transcriptional modification that allows a single gene to code for multiple proteins. In eukaryotes, gene splicing occurs prior to mRNA translation by the differential inclusion or exclusion of pre-mRNA regions. Splicing of genes is a significant source of protein diversity.
Therefore, Splicing is the correct answer.

A single gene can encode more than one type of protein through several different mechanisms, including:
How a single gene can encode more than one type of protein? Alternative splicing: This is a process in which different parts of the RNA transcribed from a gene are selectively included or excluded, resulting in the production of multiple different protein isoforms from the same gene.Post-transcriptional modifications: These are changes that occur to the RNA after it has been transcribed from the gene. For example, RNA can be edited, which can change the sequence of the encoded protein.Translation initiation: Different proteins can be produced from the same gene by starting translation at different locations.Ribosomal frame shifting: This occurs when the ribosome "slips" during translation, resulting in a different reading frame and the production of a different protein.Proteolytic cleavage: Proteins can be produced by cleaving a precursor protein into multiple functional proteins.In summary, a single gene can encode multiple proteins through alternative splicing, post-transcriptional modifications, translation initiation, ribosomal frame shifting, and proteolytic cleavage.To learn more about single gene refer:
