what do you do if you add a bit too much solvent when filling the volumetric flask to the mark
If excess solvent is added, discard the entire solution and begin the process of preparing the solution afresh.
It is common to prepare solutions using a standard volumetric flask. In this method, the required amount of solid or liquid is added to the volumetric flask and made up to mark with solvent.
Sometimes, it is possible to mistakenly exceed the mark as the solvent is added. In such cases, you must discard the entire solution and begin the process of preparing the solution afresh.

What do all atoms in a period (horizontal rows) have in common?
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.
hope this helps
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.
for a molecule to exhibit hydrogen bonding the h must be covalently bonded to a?
Answer:
: fluorine, oxygen, or nitrogen.
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.

What could be a reason for the difference between the theoretical and experimental heats of reaction
Answer:
Theoretical value is the value a scientist expects from an equation, assuming perfect or near-perfect conditions. Experimental value, on the other hand, is what is actually measured from an experiment. Rarely (in fact never) are these numbers the same.
Take the area of a sheet of paper. I know that the area of a rectangle can be found by multiplying the lengths of both sides together. I can assume an 8.5x11 sheet, so I calculate exactly 93.5 square inches. This is my theoretical value. When I actually do the measurements on my paper, it turns out my paper has been slightly cut on one end, or I’m measuring with a shoddy ruler. Therefore, I might measure only 92.8 square inches. This is my experimental value. See thats it’s close, but not exact.
Expanding on this concept, quantum mechanics is so widely accepted in the scientific community because many theoretical values calculated by mathmaticians concurred with experimental values to many, many decimal places. These would be constants such as Plank’s Constant, energy levels of harmonic potentials, and energy levels of the hydrogen atom.
Explanation:
Theoretical result is based on information and mathematics. Trials or experiments are the foundation of experimental result. What ought to occur is theoretical probability. What actually occurs is experimental probability.
What is difference between theoretical and experimental result ?The definition of theoretical probability. It is not necessary to do the experiment and then analyze the findings for theoretical probability. The theoretical probability, however, represents what you anticipate will occur in an experimnet.
In experimental probability, information is gathered via repeated experimentation. In theoretical probability, data is gathered without doing the experiment by taking into account every possibility that has a chance of occurring.
Thus, difference between the theoretical and experimental heats of reaction the incomplete combustion may result in the formation of carbon and carbon monoxide instead of carbon dioxide and water.

how does the molecular geometry change if you replace a bond with a lone pair?
Answer:
The overall molecular shape (the molecule geometry) changes because of the lone pairs repulsion, but the electron geometry does not change because whether an atom or a lone pair is added there's still two electrons being added.

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.

A student graphed the position of a cart during a 7-second time interval.
Which statement best describes the cart?
A.
The cart was stationary except for a short burst of acceleration of 0.5 m/s².
B.
The cart accelerated at a constant rate of approximately 0.8 m/s².
C.
The cart was stationary with a velocity of 0 m/s for the entire 7 seconds.
D.
The cart moved at a constant velocity of 0.5 m/s for the entire 7 seconds.
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.

Answer:
With the friction on, the minimum height I can place the skater so that he makes it all the way around the loop is 6 meters. This is about a meter higher than if the friction were turned off. The “lost” energy is going towards thermal energy. This means in real life that heat is being created due to the friction.

Can someone help me with this chemistry question?
Answer:
B no. is the answer because
Explanation:
acids increase the hydrogen ion concentration, which provides more ionsan acid comes in contact with a metal, the acid steals free electrons away. That loosens the bonds holding metal atoms in place, so the metal dissolves. That's a chemical change, so the ability of acids to dissolve metals is a chemical propertyWhen a strong acid is neutralized by a strong base there are no excess hydrogen ions left in the solution. The solution is said to be neutral as it is neither acidic nor alkaline. The pH of such a solution is close to a value of 7; the exact pH value is dependent on the temperature of the solution.So this can probably be the the answer

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