neutralizing h+ ions in a basic solution means that you add that same number of OH- to both sides and the side having h+ + oh- becomes
Answers
Neutralizing H+ ions in a basic solution means that you add the same number of OH- ions to the solution, which results in the formation of water molecules.
In a basic solution, the concentration of OH- ions is higher than that of H+ ions. Therefore, adding OH- ions to the solution neutralizes the excess H+ ions. When equal amounts of H+ and OH- ions are added, they react with each other to form water molecules (H+ + OH- → H2O).
As a result, the pH of the solution increases towards a neutral value of 7.
In summary, neutralizing H+ ions in a basic solution involves adding OH- ions to the solution, which leads to the formation of water molecules and a shift towards a neutral pH value. It is important to note that the addition of too many OH- ions can cause the solution to become too basic, which may also affect the chemical reactions occurring in the solution.

What is Decomposition Reaction
Answers
Answer:
Explanation:
Decomposition reaction, also known as analysis or dissociation, is a type of chemical reaction in which a compound breaks down into simpler substances or elements. In this reaction, a single reactant undergoes a chemical change and produces two or more products.
The decomposition reaction can be represented by the general equation:
AB → A + B
Where AB is the reactant, and A and B are the products. The reactant AB is usually a compound, and it breaks down into its constituent elements or simpler compounds.
There are different types of decomposition reactions, including:
Thermal decomposition: It occurs when a compound is heated, resulting in its decomposition into simpler substances. For example, the thermal decomposition of calcium carbonate (CaCO3) produces calcium oxide (CaO) and carbon dioxide (CO2):
CaCO3 → CaO + CO2
Electrolytic decomposition: It takes place when an electric current is passed through an electrolyte, causing it to break down into its component ions. For instance, the electrolysis of water (H2O) leads to the decomposition into hydrogen gas (H2) and oxygen gas (O2):
2H2O → 2H2 + O2
Photochemical decomposition: It occurs when a compound undergoes decomposition due to exposure to light energy. Chlorine gas (Cl2) can decompose into chlorine atoms (Cl) under the influence of light:
Cl2 → 2Cl
These are just a few examples of decomposition reactions. They are important in various chemical processes and are used in industries, laboratory experiments, and natural phenomena. By understanding and controlling decomposition reactions, scientists can gain insights into the behavior of different compounds and develop practical applications in fields such as chemistry, materials science, and environmental science.

Noble gasses are generally
Answers
Noble gases have completely filled electronic configuration. Therefore, noble gases or group 18 elements are inert in nature.
What are noble gases?Noble gases are 18th group elements in periodic table. They are all having complete filled electronic configuration. The group members are helium, neon, argon, krypton, xenon and radon.
All these elements are existing in gaseous state and they are unreactive. Atoms become reactive when they have extra electrons or are deficient of electrons. Thus to achieve octet, they bond with other atoms.
In the case of noble gases, the valence shell is already achieved octet and no need of lose or gain of electrons. Thus, they are generally inert.

calculate the ph of ammonia, which has an [h3o+] = 1.0x10−11 m.
Answers
The pH of ammonia can be calculated using the formula pH = -log[H3O+]. - [H3O+] is given as 1.0x10−11 m in the problem statement. - Taking the negative log of this concentration gives: pH = -log(1.0x10−11) pH = 11 .
The pH of a solution is a measure of its acidity or basicity. It is defined as the negative logarithm of the concentration of hydrogen ions, [H3O+]. In this problem, we are given the [H3O+] of ammonia and asked to calculate its pH using the pH formula. The pH scale ranges from 0 to 14, with values below 7 indicating acidity, values above 7 indicating basicity, and a pH of 7 indicating neutrality. In this case, the pH of ammonia is found to be 11, indicating that it is a basic solution.
To calculate the pH, we use the following formula: pH = -log10([H3O+])
In this case, the [H3O+] concentration is given as 1.0x10^-11 M. We can plug this value into the formula: pH = -log10(1.0x10^-11). Now, we can calculate the pH: pH ≈ 11.

what is the hybridization of the central atom in so2
Answers
The central atom in SO₂ is sp2 hybridized. In SO₂, the central atom is sulfur (S).
To determine the hybridization of the central atom, we need to examine the electron configuration and the number of electron domains around the central atom.
Sulfur has the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁴. The valence shell of sulfur consists of three electron domains: two sigma bonds with oxygen atoms and one lone pair of electrons.
To accommodate the three electron domains, sulfur undergoes hybridization. The electron domains are mixed to form new hybrid orbitals that are directed towards the corners of a trigonal planar geometry.
Since there are three electron domains involved in the hybridization, the sulfur atom is sp2 hybridized. The three hybrid orbitals are formed by combining one s orbital and two p orbitals.
Overall, the sp2 hybridization of sulfur in SO₂ allows for the formation of three sigma bonds and results in a trigonal planar molecular geometry.

What is the approximate volume of a 0.600 mole sample of gas at 15°C and a pressure of 1.10atm?
a. 12.9 L
b. 22.4 L
c. 24.6 L
d. 129 L
Answers
The 0.600 mole gas sample has a capacity of approximately 12.9 L at 15 °C and 1.10 atm of pressure. The right answer is (a) 12.9 L.
To calculate the volume of a gas sample, we can use the ideal gas law, PV = nRT, where P is the pressure in atm, V is the volume in liters, n is the number of moles, R is the gas constant (0.0821 L·atm/mol·K), and T is the temperature in Kelvin.
First, we need to convert the temperature from Celsius to Kelvin by adding 273.15 to it.
T = 15°C + 273.15 = 288.15 K
Now, we can rearrange the ideal gas law to solve for V:
V = (nRT) / P
Substituting the given values, we get:
V = (0.600 mol x 0.0821 L·atm/mol·K x 288.15 K) / 1.10 atm
Simplifying this expression, we get:
V ≈ 12.9 L
Therefore, the approximate volume of the 0.600 mole gas sample at 15°C and a pressure of 1.10 atm is 12.9 L. The correct option is (a) 12.9 L.

The change in energy for the reaction is \(\Delta H\) < 0, \(\Delta S\) > 0, and \(\Delta G\) < 0. Hence, option B is correct.
The chemical reaction with the loss of energy is exothermic reactions, and the reaction with the gain of energy is an endothermic reaction.
The change in enthalpy for the reaction is given by \(\Delta H\), the change in entropy is given by \(\Delta S\), and the change in free energy is given by \(\Delta G\).
What is the energy change in the exothermic reaction?The energy in the NaOH dissolution is released, which turns the solution warm.
The release of the energy by the sample in dissolution makes the value \(\Delta H\) negative.Thus, \(\Delta H\) is < 0 for the reaction.
The release of the energy results in increased disorder in the reaction mixture. The value \(\Delta S\) becomes positive.Thus, the \(\Delta S\) is > 0 for the reaction.
The reaction for the exothermic process is spontaneous. Thus, the value \(\Delta G\) is negative for the reaction.Thus, the \(\Delta G\) < 0.

where Hf is the heat of formation. According to literature, these are the heats of formation for each of the compounds in the reaction:
NaHCO3: -947.68 kJ/mol
Na2CO3: -1130.94 kJ/mol
CO2: -393.51 kJ/mol
H2O: -241.8 kJ/mol
Applying Hess' Law:
[1(-1130.94) + 1(-241.82)] + 1(-393.51)] - [2(-947.68)] = 129.09 kJ

Answers
The shortest distance between an atom's nucleus and its outermost shell is known as the atomic radius in basic chemistry. When an electron is lost the positive ionic radius is smaller than the neutral atomic radius. The correct option is B.
In a molecule, an atomic radius is equal to half the distance between neighboring atoms of the same element. While the nuclear charge does not change when an atom loses an electron, the number of electrons does. As a result, the atom's interelectronic repulsions weaken. The result is a rise in the effective nuclear charge. The result is a reduction in the atom's radius.
A cation loses valence electrons, which causes it to have a lower radius than its neutral atom. The radius of the cation is reduced as a result of the "new" valence shell being kept nearer to the nucleus.
Thus the correct option is B.
