A sample of gas has a volume of 3.50 L and a pressure of
125 mm Hg. What will the new pressure be when the volume
is decreased to 2.75 L? The temperature stays the same.
Answer:
159.09 mmHgExplanation:
The new pressure can be found by using the formula for Boyle's law which is
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question we have
[tex]P_2 = \frac{125\times3.50 }{2.75} = \frac{437.5}{2.75} \\ = 159.090909...[/tex]
We have the final answer as
159.09 mmHgHope this helps you

What is covalent bond?
Covalent bond is defined as a type of bond which is formed by the mutual sharing of electrons to form electron pairs between the two atoms.These electron pairs are called as bonding pairs or shared pair of electrons.
Due to the sharing of valence electrons , the atoms are able to achieve a stable electronic configuration . Covalent bonding involves many types of interactions like σ bonding,π bonding ,metal-to-metal bonding ,etc.
Sigma bonds are the strongest covalent bonds while the pi bonds are weaker covalent bonds .Covalent bonds are affected by electronegativities of the atoms present in the molecules.Compounds having covalent bonds have lower melting points as compared to those with ionic bonds.

¿Qué relación existe entre la teoría del octeto de Lewis con los enlaces iónicos y
covalentes?
Por definición de enlace iónico, covalente y regla del octeto, la relación existente entre la teoría del octeto de Lewis con los enlaces iónicos y covalentes es que dichos enlaces se producen con el objetivo de completar la última capa de electrones y adquirir estabilidad.
Enlace iónicoPor un lado, se produce un enlace iónico entre átomos metálicos y no metálicos, donde los electrones se transfieren completamente de un átomo a otro. Durante este proceso, un átomo pierde electrones y otro los gana, formando iones. Por lo general, el metal cede sus electrones formando un catión al elemento no metálico, que forma un anión.
Enlace covalentePor otro lado, el enlace covalente es el enlace químico entre átomos donde los electrones se comparten, formando una molécula. Se establecen enlaces covalentes entre elementos no metálicos. El par de electrones compartidos es común a los dos átomos y los mantiene unidos.
Regla del octetoEn ambos casos se cumple con la regla del octeto, que establece que los átomos de los elementos se enlazan unos a otros en el intento de completar su capa de valencia con ocho electrones. Es decir que los átomos van a tender a ceder o compartir electrones para completar ocho electrones en la capa de valencia mediante un enlace iónico, covalente o metálico.
En otras palabras, el objetivo es tener la configuración electrónica del gas noble más cercano, teniendo así la última capa de electrones completa y adquiriendo estabilidad.
En resumenEn resumen, la relación existente entre la teoría del octeto de Lewis con los enlaces iónicos y covalentes es que dichos enlaces se producen con el objetivo de completar la última capa de electrones y adquirir estabilidad.

Explanation:
methane is called an organic compound why
Answer:
Explanation:
1) Organic compounds always contain only p-block elements (Groups III-VII), at least one of which must be carbon. 2) Organic compounds almost always contain one or more C-H bonds. ... Thus, all bonds are typically covalent in organic compounds. Methane (CH4) is the prototypical organic molecule.
Methane contains carbon, forming covalent bonds, and is found in living organisms, making it an organic compound.
Methane (CH₄) is considered an organic compound due to its molecular structure and occurrence in living organisms. Organic compounds are primarily composed of carbon atoms covalently bonded to hydrogen and often other elements like oxygen, nitrogen, sulfur, and more.
Methane consists of one carbon atom bonded to four hydrogen atoms through covalent bonds. Carbon's unique ability to form stable covalent bonds with other elements, including itself, leads to the vast diversity of organic molecules found in living organisms.
Methane is a crucial component of natural gas and is produced by various biological and geological processes. It is present in the digestive systems of animals, formed during decomposition, and plays a role in carbon and energy cycles.
Its prevalence in living systems and its molecular structure classify methane as an organic compound, reflecting the foundational principles of organic chemistry.

What is oxidation state?
Answer:
a number assigned to an element in chemical combination which represents the number of electrons lost (or gained, if the number is negative), by an atom of that element in the compound
Explanation:
sodium, magnesium, iron is zero.
The definition of oxidation state is as follows: Oxidation state is a number given to the atom of an element when participating in a chemical reaction.
OXIDATION STATE:The atoms of elements are not always neutral i.e. carry no charge. They sometimes carry either positive or negative charges to become ions. Ions can either be cations (positively charged) or anions (negatively charged). The amount of charges are represented by numbers placed as a superscript in front of the element involved. These superscript charge assigned to a corresponding element during a chemical reaction is called oxidation state. The oxidation state of an element portrays the number of electrons gained or lost during the reaction.Therefore, oxidation state can be defined as a number given to the atom of an element when participating in a chemical reaction.

Answer: 3-nitropyridine
Explanation:
the proton concentrations of three solutions at 25 °c are given. classify the solutions as acidic, basic, or neutral.
This problem is giving information about the proton concentrations of three solutions at 25 °C. Despite they are not numerically given, we can propose three scenarios to see how to approach the question.
Let the following solutions to come up:
[H⁺] = 2.63x10⁻³ M
[H⁺] = 1.00x10⁻⁷ M
[H⁺] = 4.511x10⁻⁹ M
The first step, will be the calculation of the pH for each solution via:
pH = -log([H⁺])
So that they turn out to be:
pH = -log(2.63x10⁻³ M) = 2.580
pH = -log(1.00x10⁻⁷ M) = 7.000
pH = -log(4.511x10⁻⁹ M) = 8.3457
In such a way, since acidic solutions have a pH below 7, neutral have a pH equal to 7 and basic have it above 7, we infer the first one is acidic, second one is neutral and third one is basic.
Thus, you can reproduce this methodology with the proton concentrations you are given.
