According to above statement, HCl ( Hydrochloric acid ) is a strong acid, which when mixed in water dissociates complete in water to form H+ and Cl- ions that means 100% dissociation. but acids weaker than HCl shows relatively less dissociation.

That is less than 100% dissociation when mixed in water ~

This information tells us about the relative dissociation of weaker acids is that weaker acids dissociates less than 100%.

Dissociation is defined as the breaking up of a compound into simpler constituents or components or parts. Ionic compounds dissociates in the water solution. Stronger acids have 100% ability to dissociate.

So we can conclude that this information tells us about the relative dissociation of weaker acids is that weaker acids dissociates less than 100%.

The statement that is true of entropy changes is the correct option is the entropy of a substance is influenced by the structure of the particles that comprise the substance.

The Heavier atoms will possess the greater entropy at the given temperature than the lighter atoms and the entropy of the substance will be  influenced by the structure of the particles that is comprise the substance. The Entropy is the measure of the randomness or the disorders .

The entropy decreases that is the ΔS < 0 as the substance will transforms from the gas to the liquid and then to the solid.

Answer:

Explanation:

Correct number to balance the equation: ___KClO3 → 2KCl 3O2 is "2".

We obtain KCl and oxygen gas from the breakdown of potassium chlorate (KClO3).

1.5 moles of O2 gas and one mole of KCl are produced from one mole of KClO3.

Therefore, the response will be:

KCL)3 - - > KCL + 3/2 O2

The entire equation will be multiplied by two in order to transform the fractional coefficient to a whole number.

2X [ KCLO3 - - > KCL + 3/2 O2 ]

A balanced equation will therefore be:

2KCLO3 - - > 2KCL + 3 O2

KClO3's coefficient is therefore "2".

Explanation:

because the dissolved salt is evenly distributed throughout

The distribution of electrons among orbitals in a many-electron atom is known as its electron configuration.

The electron configuration describes how electrons are distributed in the various energy levels and orbitals around the nucleus of an atom. It is represented using a series of numbers and letters that indicate the principal energy level (n), the type of orbital (s, p, d, f), and the number of electrons in each orbital.

For example, the electron configuration for carbon (C) is 1s^2 2s^2 2p^2, which shows that carbon has two electrons in the 1s orbital, two electrons in the 2s orbital, and two electrons in the 2p orbital.

The electron configuration provides important information about the arrangement and organization of electrons within an atom, which in turn affects the atom's chemical properties and reactivity.

Answer:

option D and option B

Explanation:

water and bromine both belongs to inorganic compund..

The mass of the sample increased, so a chemical change occurred when bonds formed between the metal and another substance. Option B

We define a chemical change as on in which there is the formation of a new substance. Thus of we look at the system, we would notice that there is the formation of a new substance as the bonds to the reactants are broken and new bonds are made.

In the case of a physical change , there is nor formation of a new substance thus what we just have could be that the substances would move from a given physical state to the other and the mass of the system is just going to remain the same as it was at the beginning.

Since the mass was increased, then we could say that a chemical change has taken place as new bonds are formed.

If a titration net volume should be 20. 00 ml and a student accidentally goes one drop past the endpoint (~0. 05 ml),then the percent error is 0.25%.

Percent error is defined as the difference of experimental value and theoretical value and measures the accuracy of the result found. The greater the error, lesser is the accuracy and vice versa.

Vd = 1mL/20 drops

where,

Vd is volume of one drop

Vd = 0.05mL

Error is defined as the ratio of change in volume divided by real volume.

e(%) = {(Vr-Vt) /Vt}×100

where,

Vr = real volume

Vd = theoretical volume

e(%) = {((20+0.05) -20) /20} × 100

e(%) = 0.25%

Thus, we find that the percent error on adding one drop is 0.25%.

Answer:

2 oxygen atoms make oxygen gas

A molecule of oxygen gas is composed of two oxygen atoms chemically bonded together. The symbol for oxygen is "O," and the atomic number is 8, indicating that each oxygen atom has 8 protons in its nucleus.

A covalent bond is a type of chemical bond that occurs between two atoms when they share one or more pairs of electrons. It is a strong bond that holds atoms together to form molecules.

In a covalent bond, atoms share electrons in order to achieve a more stable electron configuration, typically by filling their outermost energy levels (valence shells). By sharing electrons, both atoms involved in the bond can achieve a more stable configuration, similar to the noble gas configuration.

In an oxygen gas molecule, the two oxygen atoms are held together by a covalent bond. Covalent bonds involve the sharing of electron pairs between atoms. In the case of oxygen gas, each oxygen atom shares two electrons with the other oxygen atom, resulting in a stable molecule.

Therefore, a molecule of oxygen gas is made up of two oxygen atoms (O) bonded together by a covalent bond.

Ketoses such as fructose are expected to give a positive Tollens test because of their ability to reduce Tollens' reagent.

The Tollens test is a chemical reaction used to test for the presence of aldehydes. The test is named after the German chemist Bernhard Tollens. The Tollens reagent is a solution of ammoniacal silver nitrate, Ag(NH3)2NO3. The test is based on the fact that aldehydes are readily oxidized to carboxylic acids by a solution of silver nitrate in ammonia.

This reaction is exothermic and produces a silver mirror on the inside of the test tube.The test solution is prepared by adding a few drops of a solution of Tollens' reagent to the substance being tested. The test solution is then heated in a water bath for a few minutes.

If the substance being tested is an aldehyde, it will reduce the silver ions in the Tollens' reagent to metallic silver. The metallic silver will form a mirror on the inside of the test tube. If the substance being tested is not an aldehyde, no mirror will form.The aldehydes are more easily oxidized than the ketoses.

The given statement suggests that CaCl₂ is dissolved in water. We are required to identify which of the given steps is not involved in this solvation process.

The three steps involved in the solvation process are dissociation, ionization, and hydration. Out of these three steps, ionization is not involved in the solvation process of CaCl₂ in water.Ionization is the process of forming ions by losing or gaining electrons, whereas dissociation is the separation of a molecule into ions.

Hydration is the process in which ions of an ionic compound get surrounded by water molecules in solution. When CaCl₂ is dissolved in water, it dissociates into its respective ions, Ca²⁺ and 2Cl⁻. Hence, dissociation and hydration occur during the solvation process of CaCl₂ in water.

Therefore, the answer to this question is that ionization is not involved in the solvation process of CaCl₂ in water.In conclusion, CaCl₂ dissolves in water through dissociation and hydration processes.

Dissociation separates it into Ca²⁺ and 2Cl⁻ ions, whereas hydration involves the surrounding of these ions by water molecules. Ionization is not involved in the solvation process of CaCl₂ in water.
