Option C: Neutron is the subatomic particles that could be changed without changing the identity of the atom.

The number of protons in an atom is indicated by the atomic number. As a result, when the amount of protons changes, the atomic number also changes, changing the element's identity. An element's atomic mass changes when its neutron count is altered, but its identity is preserved. An element's charge changes as its electrons are lost or acquired, but its identity is unaffected. Thus, option C is the correct choice.

Protons, neutrons, and electrons are the three subatomic particles that make up an atom. Neutrons are neutrally charged particles, whereas protons are positively charged. The opposite of this is true of electrons, which have a negative charge. Protons and neutrons are found in the nucleus of an atom. An element's atomic number allows it to be recognised from other elements.

The answer is not provided, as the amount of nitric oxide produced depends on the amount of ammonia used in the reaction.

Nitric oxide (NO) is a colorless and odorless gas that acts as a signaling molecule in the human body. It is produced within the cells of many organisms, including humans, and plays an important role in many physiological and pathological processes. It is a key component of the cardiovascular system, where it is responsible for regulating blood pressure, dilating arteries, and preventing platelet aggregation. NO also acts as a neurotransmitter in the nervous system, where it is involved in learning, memory, and pain modulation. In addition, it has anti-inflammatory and anti-tumor properties and is involved in wound healing and immune functioning. NO also plays a role in the regulation of cell metabolism and growth.

Colorless and odorless, monoxide (CO) seems to be a gas. It is emitted by a number of combustion, including as cars, electric utilities, wildfires, and incinerators, and it is caused by the fuel burning of carbon-containing fuels like oil and gas, gasoline, etc wood.

A substance called carbon cyanide is created when shale gas or other carbon-containing materials are burned partially. This includes production emissions, fires, malfunctioning heaters, and exhaust.

Intermolecular forces operate between molecules. In contrast, intramolecular pressures are produced by molecules themselves. Intermolecular forces are less powerful than intramolecular forces. Intermolecular forces include the Interatomic force, particle contact, ion-dipole involvement, and interactions by van der Waals to name a few.

The two primary categories of intermolecular interactions are attracting forces as well as repulsive forces. Electrostatic forces are principally responsible for the attraction. The connection between four or more material elements, nevertheless, could also be caused by other factors.

The pressure of the gas can be determined using ideal gas equation. The pressure of neon in the tank is 9.7 atm.

Ideal gas equations states the relation between volume, pressure, temperature and number of moles of gas as written below:

PV = nRT.

Where R is the universal gas constant equal to 0.082 L atm/K mol.

Given the volume of the tank  V = 10 L

number of moles n = 4 moles

temperature  = 22 ° C = 295 k

Then pressure P = nRT/V.

Pressure of neon gas = 4 moles × 295 K× 0.082 L atm/K mol /(10 L)

P = 9.7 atm.

Al2O3 does not use Greek prefixes since it is an ionic compound, while N2O3 does use Greek prefixes since it is a molecular compound.

A molecular compound is a chemical compound consisting of two or more atoms held together by covalent bonds. Covalent bonds are formed when atoms share one or more of their electrons with another atom in order to complete their outer electron shell.

The main difference between Al2O3 (aluminum oxide) and N2O3 (dinitrogen trioxide) is that Al2O3 is an ionic compound (made up of charged ions) and N2O3 is a molecular compound (made up of covalently bonded molecules). Therefore, the naming conventions for these two types of compounds are different. For ionic compounds, the name includes the names of the cation and anion (aluminum and oxide, respectively) and their charges (Al2+ and O3-). For molecular compounds, the prefixes are taken from the Greek language to indicate the number of atoms of each element in the molecule (di- for two nitrogen atoms and tri- for three oxygen atoms). Therefore, Al2O3 does not use Greek prefixes since it is an ionic compound, while N2O3 does use Greek prefixes since it is a molecular compound.

The appropriate law for this problem is Graham's Law of Effusion and Diffusion.

Appropriate law is the legal framework and regulations that are established to ensure fairness and justice within a society. It defines the rights and responsibilities of individuals, businesses, and governments, and helps to promote the public good.

Graham's Law states that the rate of effusion or diffusion of a gas is inversely proportional to the square root of its molecular weight. This means that the lighter the gas, the faster the rate of effusion or diffusion. In this case, u-235 has an atomic mass of 235 g/mol, while u-238 has an atomic mass of 238 g/mol. This makes u-235 the lighter gas, so it will diffuse faster than u-238. Therefore, the answers to the questions are:

u-235 diffused 1.01 times faster than u-238

u-235 effused 1.01 times slower than u-238

A million (1.0 ×10^6) vanadium atoms are present in 1.510 ×10^13 g of vanadium(v) oxide (v2o5).

Vanadium atom count: 1,000 to 10^^9 atoms

Step 2: Determine the V2O5 molecules with 1.000× 10^9 V atoms.

V2O5 molecules contain 2 V atoms each.

0.5000× 10^9 molecule V2O5 = 1.000 109 atom V (1 molecule V2O5/2 atom V)

Step 3: Determine the number of moles that equate to 0.5000× 10^9 molecules of V2O5.

We shall utilize Avogadro's number: 6.022 x 10^23 molecules of V2O5 make up 1 mole of the substance.

1 mol/6.022 10^23 molecules divided by 0.5000 109 molecules equals 8.303 10^16 molecules.

Aqueous phase is a term used to describe a solution in which water is the solvent. This type of solution is commonly used in chemistry, as water is an excellent solvent for many different types of compounds. In an aqueous solution, the molecules of the solute are dissolved into the water molecules and are then evenly distributed throughout the solution. This process is driven by the strong intermolecular forces between water molecules, which allows them to attract and form strong bonds with other molecules.

To balance the redox reaction in basic solution between cyanide and silver, first write the unbalanced equation containing all the reactants and products of the chemical reaction.

Ag(s) + CN-(aq) + O2(aq) → Ag(CN)2- + OH-(aq)

Subsequently, the redox reaction is divided into partial reactions, that is, the oxidation and reduction reactions are indicated, determining the oxidation numbers of each atom that appears in the reaction.

Ag0 + C+2N-3- + O02 → Ag+1(C+2N-3)2- + O-2H+1-

The redox pairs of all atoms that have been oxidized and all atoms that have been reduced are then identified.

Subsequently, the redox couples combine in two partial reactions: one oxidation and one reduction.

Then the atoms in the partial equations are balanced by adding the appropriate coefficient in front of the formula.

Ag0 + 2CN- → Ag+1(C+2N-3)2- + e-

Next, the number of electrons lost and received is equalized, we will multiply the two equations by the factor that will give the least common multiplier.

Add the partial equations so that on one side are all the products and on the other are all the reactants.

4Ag0 + O02 + 8CN- + 4e- + 4H2O → 4Ag+1(C+2N-3)2- + 2H+12O-2 + 4e- + 4OH-

Answer:

Explanation:

15.0 mL of vinegar is equivalent to 15.0 g of vinegar, since the density of vinegar is 1.0 g/mL. Vinegar is composed of mostly acetic acid (CH3COOH) and water. The density of acetic acid is 1.05 g/mL, so 15.0 mL of vinegar is equivalent to approximately 14.3 g of acetic acid.

The balanced equation for the reaction between sodium bicarbonate (baking soda) and acetic acid is:

NaHCO3 + CH3COOH → NaCH3COO + H2O + CO2

For every mole of acetic acid, we need one mole of sodium bicarbonate. We can use the molar mass of acetic acid (60.05 g/mol) and sodium bicarbonate (84.01 g/mol) to calculate the amount of baking soda needed.

14.3 g of acetic acid x (1 mol/60.05 g) = 0.238 mol acetic acid

0.238 mol acetic acid x (84.01 g/mol) = 19.9 g baking soda

Therefore, 19.9 g of baking soda is needed to react with the 15.0 g of acetic acid in 15.0 mL of vinegar.
