The percent by mass of each compound in the mixture is 24.04% NaBr and 75.96% Na₂SO₄.
Percentage by mass, mass %, is a measure of concentration that indicates the mass of solute per mass of solution. In other words, the mass percent of a component in the solution is defined as the ratio of the mass of the component to the mass of the solution, expressed as a percentage.
mass % = (mass of solute / mass of solution) x 100
In the case of a mixture of NaBr and Na₂SO₄ that contains 29.96% Na by mass, assume 100 g of the mixture.
Let x = mass of NaBr
100 - x = mass of Na₂SO₄
29.96 g = mass of Na in NaBr + mass of Na in Na₂SO₄
29.96 g = (mass of NaBr)(mass % Na in NaBr/100) + (mass of Na₂SO₄)(mass % Na in Na₂SO₄/100)
29.96 g = (x)(22.989769/102.893769) + (100 - x)(2 · 22.989769/142.040538)
29.96 g = 0.2234320817x + (100 - x)(0.3237071518)
29.96 g = 0.2234320817x + 32.37071518 - 0.3237071518x
0.3237071518x - 0.2234320817x = 32.37071518 - 29.96
x = 24.04102213
100 - x = 100 - 24.04102213 = 75.95897787
mass % NaBr = (mass of NaBr / mass of mixture) x 100
mass % NaBr = (24.04102213 / 100) x 100
mass % NaBr = 24.04102213
mass % Na₂SO₄ = (mass of Na₂SO₄ / mass of mixture) x 100
mass % Na₂SO₄ = (75.95897787 / 100) x 100
mass % Na₂SO₄ = 75.95897787
Hence, the mass % of each compound is 24.04% NaBr and 75.96% Na₂SO₄.

Which type of isomers are o-xylene, m-xylene, and p-xylene?
structural isomers
optical isomers
geometric isomers
o-xylene, m-xylene, and p-xylene are structural isomers.
o-xylene, m-xylene, and p-xylene are examples of aromatic isomers, also known as ortho-, meta-, and para-xylene, respectively. These isomers are classified as aromatic because they are part of a family of compounds known as aromatic hydrocarbons, which contain a ring of six carbon atoms bonded to each other in a specific way.
o-xylene, m-xylene, and p-xylene are also examples of structural isomers. Structural isomers are compounds that have the same molecular formula but differ in the arrangement of their atoms. In the case of o-xylene, m-xylene, and p-xylene, the atoms are arranged differently around the ring of six carbon atoms.
o-xylene, m-xylene, and p-xylene are not optical isomers, which are also known as enantiomers. Optical isomers are compounds that are mirror images of each other but are not superimposable. Optical isomers are important in medicinal chemistry because they can have different biological properties even though they have the same molecular formula and structure.
o-xylene, m-xylene, and p-xylene are also not geometric isomers. Geometric isomers are compounds that have the same molecular formula and the same arrangement of atoms, but differ in the orientation of their atoms or groups of atoms in space. Geometric isomers are often found in compounds with cis-trans double bonds or ring structures.

when 2.16g of h2 reacts with excess o2 by the following equation, 258kj of heat are released. the change of enthalpy associated with the reaction of 1.00mol of hydrogen gas is -241 KJ
Molar mass of H2 = 2.016 g/mol,mass(H2)= 2.16 g
use:number of mol of H2,n = mass of H2/molar mass of H2=(2.16 g)/(2.016 g/mol) = 1.071 mol
For 1.071 mol of H2, heat released = 258 KJ So,
for 1 mol, heat released = 258/1.071 KJ = 241 KJ
Since this is heat released, sign will be negative
Answer: -241 KJ. The amount of energy progressed or subsumed in a reaction at constant pressure is referred to as enthalpy change. It is represented by the symbol ΔH, read as "delta H". It should be noted that the term "enthalpy change" only pertains to reactions performed at constant pressure.

The apple farmer is able to obtain 8,034.6 oranges by trading 0.64 of his orchard.
How to determine how many oranges he is able to obtain by trading 0.64 of his orchard?
A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation
First, let's find the total number of apples produced by the orchard:
20 trees × 418 apples/tree = 8,360 apples
Now, let's find the number of apples that the apple farmer is able to trade: 8,360 apples × 0.64 = 5,350.4 apples
Since the apple farmer wants to trade 3 oranges for every 2 apples, he will be able to obtain:
3 oranges / 2 apples × 5,350.4 apples = 8,025.6 oranges.

How specifically is kinetic energy lost during a car crash?
Answer + Explanation:
During a car crash, kinetic energy is lost through various forms of deformation of the vehicle and the generation of heat.
When a car collides with another object, the force of the impact causes the vehicle's body and structure to deform. This deformation absorbs some of the kinetic energy and converts it into other forms of energy, such as heat and sound.
In addition, friction between the moving parts of the car and between the car and the road can also generate heat, which absorbs some of the kinetic energy.
The amount of kinetic energy lost during a car crash depends on the mass of the vehicle, the speed at which it was traveling, and the type and severity of the collision. In general, higher speeds and more severe collisions result in greater kinetic energy loss.
Look at the equation.

We then have that;
Number of moles of the ethylene = 55.0 grams/28 g/mol

If one form of a gene can mask the appearance of another form, that form is considered dominant over the other form. Option B.
What are dominant alleles?According to Mendel, genes are usually made up of 2 alleles. These alleles can be the same or different. When the alleles are the same, the gene is said to be homozygous. If the alleles are different, the gene is said to be heterozygous.
When the two alleles that make up a gene are different, one will be dominant and the other will be recessive. The dominant gene masks the effect of the recessive gene. In other words, the recessive gene cannot be expressed as long as it coexists with the dominant gene. In order for it to be expressed, it has to be in two copies or a homozygous recessive form.
For the dominant allele, however, only one copy is needed for it to be expressed.

What does aerobic decomposition produce?
Compost, water (both liquid leachate and gaseous vapor), and volatilized gases are all products of aerobic composting (ammonia, carbon dioxide and, occasionally, gases perceived as odors). Digestate and biogas are created during anaerobic digestion.
Is aerobic decomposition faster than anaerobic?
You can get finished compost sooner if there is enough air available because aerobic decomposers function faster and more effectively than their anaerobic cousins.
The aerobic composting produces water vapor, carbon dioxide and a black organic material.To know more about aerobic decomposition:

Nuclear Fission include used in nuclear power plants and byproducts have long half-lives, Nuclear fusion includes occurs on the sun and needs very high temperatures, while Nuclear fission and Nuclear fusion includes release lots of energy.
What are Nuclear fission nuclear and Nuclear fusion?Nuclear fission is a physico chemical process caused when an atom divides into two smaller atoms, which released important amounts of energy and it is used to generate electricity in nuclear power plants.
Conversely, Nuclear fusion occurs when smaller atoms such as hydrogen fuse to form larger atoms, which is able to generate much more energy when compares to Nuclear fusion, and this process fuel energy in the sun.
Therefore, with this data, we can see that fission nuclear and fusion nuclear are very different processes in terms of the division of fusion of atoms and they release differential amounts of energy.
