Accelerants are flammable solvents such as kerosine, turpentine, gasoline etc. Therefore, the accelerant obtained from the crime scene here, is gasoline.

Accelerants are substances that can combine, blending, or disturb another substance, causing the speed of a natural or artificial chemical process to increase. Accelerants are important in chemistry because they can speed up most chemical reactions.

Accelerants change a chemical bond, accelerate a chemical process, or restore organisms to homeostasis. Accelerants are not always catalysts because they can be consumed by the process.

Flammable gases or solvents such as gasoline, diesel, butane gas, kerosine, turpentine etc are examples of accelerants. Therefore, among the given substances , gasoline is the accelerant.

Answer:   Germanium has a cubic closest packed structure as a solid. Assuming that germanium has an atomic radius of 159 pm, calculate the density of solid germanium. __________ g/cm3 b.) Germanium has a face-centered cubic unit cell. The density of germanium is 5.32 g/cm3. Calculate a value for the atomic radius of germanium. ___________pm c.) You are given a small bar of an unknown metal X. You find the density of the metal to be 12.0 g/cm3. An X-ray diffraction experiment measures the edge of the face-centered cubic unit cell as 3.89 â„« (1 â„« = 1 ✕ 10−10 m). Identify X.

Explanation:

The density of Germanium is equal to 5.30g/cm^3

Data Given;

For a cubic closest packed = 4r

[tex]4r = \sqrt{2a} \\ a = \frac{4}{\sqrt{2} }r\\ a = \frac{4}{2}*159*10^-^1^0\\ a = 4.50*10^-^8cm[/tex]

The density of the cube is given as the ratio between the mass and volume. But in this case, we have a formula

[tex]d = \frac{Zm}{Na^3}\\ d = \frac{4*72.64}{6.023*10^2^3*9.09*10^-^2^3}\\ d = 5.30 g/cm^3[/tex]

NB;

The density of the cube is equal to 5.30g/cm^3

Answer:

Explanation:

The collision theory explains why reactions occur between atoms, ions, and molecules. With the increase in temperature, there is an increase in the number of collisions. Increasing the concentration of a reactant increases the frequency of collisions between reactants and will, therefore, increase the reaction rate.

Answer:

Un par solitario o par de electrones no compartidos es un par de electrones de valencia que no se encuentra formando un enlace, ni compartido con otros átomos. Cuando un átomo se agrupa con otros para formar una molécula, sus electrones más externos -también conocidos como electrones de capa de valencia- dejan de pertenecer únicamente al átomo del que provienen, pasando a pertenecer a la molécula formada. Los orbitales atómicos de valencia dejan de existir como tales y pasan a formar orbitales moleculares con características diferentes a las originales. Como los pares solitarios se encuentran en la capa más externa de los átomos, cuando estos átomos forman moléculas pasan a formar parte del conjunto de electrones de valencia de la molécula. De esto se deduce que los pares solitarios son, de hecho, un subconjunto de los electrones de valencia de la molécula a la que pertenecen.

Explanation:

Hydrogen bonding occurs only in molecules where hydrogen is covalently bonded to one of three elements: fluorine, oxygen, or nitrogen.

Hydrogen bonding occurs only in molecules where hydrogen is covalently bonded to one of three elements: fluorine, oxygen, or nitrogen. These three elements are so electronegative that they withdraw the majority of the electron density in the covalent bond with hydrogen, leaving the H atom very electron-deficient. The H atom nearly acts as a bare proton, leaving it very attracted to lone pair electrons on a nearby atom.

2. Concentration of reactants and products are the same.

Answer:

All of the elements in a period have the same number of atomic orbitals. For example, every element in the top row (the first period) has one orbital for its electrons. All of the elements in the second row (the second period) have two orbitals for their electrons.

Explanation:

Elements in the same period are those that are in a single horizontal line from left to right. They do not share the same type of chemical reactivity as seen in groups. They only real thing that these elements share in common is the same principal quantum number, or main energy shell.

The cart accelerated at a constant rate of approximately 0.8 m/s². Option (B) is correct.

Option B is the best description based on the graphed position data during the 7-second time interval. The cart's acceleration can be determined by analyzing the shape of the position-time graph.

If the cart was stationary, the position-time graph would be a horizontal line (option C). If the cart moved at a constant velocity, the graph would be a straight line inclined at a constant angle (option D).

However, the graph likely shows a curved line, indicating changing position over time. This suggests that the cart experienced acceleration. To further confirm, calculate the acceleration:

Acceleration (a) = Δv / Δt,

where Δv is the change in velocity and Δt is the change in time.

Given the time interval is 7 seconds, and the initial and final velocities are likely different, you can calculate the average acceleration. If the average acceleration is approximately 0.8 m/s², then option B is correct.

The graphed data aligns with the scenario of constant acceleration, supporting option B.
