Which form of emission is commonly not written in nuclear equations because they do not affect charges, atomic numbers, or mass numbers?
alpha particle
beta particle
gamma ray
Answer: It is Gamma ray
Answer:
C. gamma ray
(Photo for proof at the bottom.)
Explanation:
A gamma ray is a type of radiation that occurs when an unstable nucleus emits a photon, the smallest unit of light. A photon has no mass or charge. Atomic and mass numbers are written based on the mass of the atom. But since no mass is lost when a photon is emitted, writing the emission of it isn't necessary.

How do gas particles respond to an increase in volume?
When the volume of a gas is increased, the gas particles respond by spreading out and occupying a larger space. This results in a decrease in the density of the gas and a decrease in the frequency of collisions between the gas particles.
How do gas particles respond to an increase in volume?As the gas particles spread out, the pressure exerted by the gas decreases.
This is because the pressure of a gas is directly proportional to the number of collisions per unit area of the container walls. When the volume increases, the same number of gas particles are distributed over a larger area, reducing the frequency of collisions and thus decreasing the pressure.
In summary, an increase in volume causes gas particles to spread out, resulting in a decrease in density and a decrease in pressure.

How does the composition of the nucleus change during fission, fusion, and radioactive decay?
The composition and mass of the nucleus changes during fission, fusion and nuclear decay process. During fission the nuclei breaks to light nuclei and in fusion the mass of nuclei formed is increased and in radioactive decay, the nuclear mass decreases.
What is nuclear fission?Nuclear fission is the process of breaking of a heavy nucleus into light nuclei with the release of energy. Hence, fission changes the identity of the atomic nuclei and form to light nucleus.
In nuclear fusion, two light nuclei fused up to form a heavy nucleus. Hence, the new composition changes the identity of the product. The number of protons, neutrons or electrons are differed in both fusion or fission.
Radioactive elements undergo nuclear decay by the emission of charged particles and it will reduce the atomic number or mass number or both based on the type of decay.

A blue light is shined on objects X and Y. Object X appears to be blue, and object Y appears to be black when Object X reflects blue light, and object Y absorbs blue light. Hence option B is correct.
What is light ?Visible light spectrum is nothing but the range of wavelength of radiation from 4000 angstrom to 7000 angstrom(Violet to Red). light is a energy packet. Every Photon having different wavelength travels with same velocity c (velocity of light). When we focus numbers of colors from visible spectrum to a point, that point appears as a white light. hence white light is composed of numbers of Colors in it.
When we pass white light through a prism, as white light enters in the prism all the colors having different wavelength travels with different velocity in the prism due to that there is separation of colors from the white light. Therefore we get different colors of white light in the prism this phenomenon is know as dispersion of light.
Light can be reflected, absorbed, transmitted diffracted and scattered etc.
α + β + ν = 1 where α, β, ν are coefficient of absorption, reflection and transmission.
When any object appears to be black it means that radiation has been absorbed by that body, it has high absorption coefficient. and when a body appears to be colored, it means that object has reflected the particular color, it having high reflection coefficient.
Hence option B is correct.

3. 7moles of Ba(NO3)2 is dissolved in 75kg of distilled water.
What is the boiling point of this solution? Hint: Find molality first.
Answer:
100.14°C
Explanation:
The boling point elevation is a colligative property that describes the increasing in boiling point of a solution regard to the boiling point of the pure solvent. The equation is:
ΔT = Kf*m*i
Where ΔT is boiling point elevation
Kf is boiling point elevation (0.51°C/m for water)
m is molality of the solution (7moles Ba(NO3)2 / 75kg = 0.09333m
i is Van't Hoff factor = 3 for Ba(NO3)2 (Because its dissolution produce 3 ions = Ba²⁺ and 2 NO₃⁻
Replacing:
ΔT = 0.51°C/m*0.09333m*3
ΔT = 0.14°C is the boiling point elevation
As the boiling point of water is 100°C, the boiling point of the solution is:
100°C + 0.14°C =
100.14°C

Glycerol has a molar mass of 92.09g/mol. Its percent composition is: 39.12% C, 8.75% H,
and 51.12% O. What is the molecular formula for glycerol?
Answer:
Molecular formula => C₃H₈O₃
Explanation:
From the question given above, the following data were obtained:
Carbon (C) = 39.12%
Hydrogen (H) = 8.75%
Oxygen (O) = 51.12%
Molar mass of compound = 92.09 g/mol
Molecular formula =?
Next, we shall determine the empirical formula of the compound. This can be obtained as follow:
C = 39.12%
H = 8.75%
O = 51.12%
Divide by their molar mass
C = 39.12 / 12 = 3.26
H = 8.75 / 1 = 8.75
O = 51.12 / 16 = 3.195
Divide by the smallest
C = 3.26 / 3.195 = 1
H = 8.75 / 3.195 = 2.7
O = 3.195 / 3.195 = 1
Thus, the empirical formula is CH₂.₇O
Finally, we shall determine the molecular formula of the compound. This can be obtained as follow:
Empirical formula = CH₂.₇O
Molar mass of compound = 92.09 g/mol
Molecular formula =?
Molecular formula = Empirical formula × n
Molecular formula = [CH₂.₇O]ₙ
92.09 = [12 + (2.7×1) + 16] × n
92.09 = 30.7n
Divide both side by 30.7
n = 92.09 / 30.7
n = 3
Molecular formula = [CH₂.₇O]ₙ
Molecular formula = [CH₂.₇O]₃
Molecular formula = C₃H₈O₃

Consider the chemical equation. 2NBr3 + 3NaOH Right arrow. N2 + 3NaBr + 3HOBr If there are 40 mol of NBr3 and 48 mol of NaOH, what is the excess reactant?
Answer:
NBr₃ is the excess reactant.
Explanation:
2NBr₃ + 3NaOH → N₂ + 3NaBr + 3HOBrWe can solve this problem by calculating how many moles of NaOH would react completely with 40 moles of NBr₃, using the stoichiometric coefficients of the reaction:
40 mol NBr₃ * [tex]\frac{3molNaOH}{2molNBr_3}[/tex] =60 moles NaOHAs the required number of NaOH moles is higher than the available number (60 required vs 48 available), NaOH is the limiting reactant.
As such, the excess reactant is NBr₃.
