False
True

Answers

Answer: True. The primary distinction between chemical reactions and nuclear reactions is that chemical reactions involve the flow of electrons, while nuclear reactions involve changes to protons and neutrons. In chemical reactions, atoms form new bonds with other atoms by gaining, losing, or sharing electrons. In nuclear reactions, the protons and neutrons in the nucleus of an atom are rearranged to form new elements. These two types of reactions are fundamentally different and involve different types of particles and energy.

Answers

Powerful molecular forces Intermolecular forces that are weak Answer bank High surface tension, high viscosity, high vapor pressure, and high boiling point.

A liquid's resistance to flowing is determined by its viscosity. Viscosity is a measure of how strongly intermolecular forces are present in a liquid. All four parameters—boiling point, melting temperature, surface tension, and viscosity—decline significantly. The substance's vapor pressure rises as a result of the molecules' easy escape due to weak forces. In a closed container, vapor pressure develops when liquid molecules have enough kinetic energy to break free from the intermolecular interactions and transform into a gas. The magnitude of intermolecular forces has an inverse relationship with vapor pressure.

5. A solid consists of a mixture of NaNO3 and Mg(NO3)2. When 6.50 g of the solid is dissolved in 50.0 g of water, the freezing point of the solution is lowered by 5.23°C. What is the composition by mass of the solid mixture?​

Answers

The mass of the solid mixture can be determined from the molality and depression in freezing point of the solution. The mass obtained for the solution is 46.4 g.

What is depression in freezing point?

Freezing point of a solution decreases from that of pure solvent when  a non-volatile solute is added into it. The depression in freezing point ΔT is proportional to the molality of the solution.

ΔT = Kf m

Where Kf is the molal depression constant. Kf for water is 1.86 K /(mol Kg)

Given that ΔT = 5.23 °C

m = ΔT / Kf

   = 5.23  °C / 1.86 K /(mol Kg)

   = 2.811 m

Molality = no.of moles of the solid mixture/ mass of solvent in Kg.

no. of moles = molality × solvent mass

= 2.811 m × 0.05 Kg = 0.140 moles

Given the weight of the solid mixture = 6.50g

Hence, its composition by mass = 6.50/ 0.140 moles = 46.4 g.

Therefore, the composition by mass of the solid mixture is 46.4 g.

A covalent bond occurs when atoms share one or more pairs of electrons to form a stable molecule. The difference in electronegativity between two atoms plays a role in determining the type of bond formed between them. In general, covalent bonds are formed between atoms with similar electronegativities.

A covalent bond can form between two atoms if the electronegativity difference between them is less than 1.7. However, the size of the atoms is not the determining factor in covalent bond formation. Instead, the atomic electron distribution and electron affinity are very important.

In general, covalent bonding is a key process in chemistry that allows atoms to form stable bonds with each other. It is a key factor in determining the properties of various chemical compounds such as gases, liquids and solids.

Which of these reactions leads to a change in the hybridization of one or more carbon atoms? oxidation of an alcohol to yield a carboxylic acid neutralization of an amine using a strong mineral substitution of an aromatic ring using a halogen free radical halogenation of an alkane hydrolysis of an ester to yield an acid and an alcohol

Answers

All of these reactions can potentially lead to a change in the hybridization of one or more carbon atoms, but the extent of the change and the specific details of the reaction will depend on the specific reaction being considered.

Oxidation of an alcohol to yield a carboxylic acid: This reaction typically involves the addition of an oxygen atom to the carbon atom that was bonded to the hydroxyl group in the alcohol, as well as the removal of two hydrogen atoms. This can result in a change in the hybridization of the carbon atom, depending on the specific alcohol being oxidized and the conditions of the reaction.

Neutralization of an amine using a strong mineral acid: This reaction typically involves the addition of a proton to the nitrogen atom in the amine, as well as the removal of a hydroxyl group. This can result in a change in the hybridization of the nitrogen atom, depending on the specific amine being neutralized and the conditions of the reaction.

Substitution of an aromatic ring using a halogen: This reaction typically involves the substitution of a hydrogen atom on the aromatic ring with a halogen atom. This can result in a change in the hybridization of the carbon atom bonded to the hydrogen atom that is replaced, depending on the specific aromatic compound and the conditions of the reaction.

Halogenation of an alkane: This reaction typically involves the substitution of one or more hydrogen atoms on an alkane with a halogen atom. This can result in a change in the hybridization of the carbon atoms bonded to the hydrogen atoms that are replaced, depending on the specific alkane and the conditions of the reaction.

Hydrolysis of an ester to yield an acid and an alcohol: This reaction typically involves the addition of a hydroxyl group to the carbon atom that was bonded to the ester group, as well as the removal of the oxygen atom that was bonded to the same carbon atom.

write short note about acid nomenclature​

Answers

Acids

There are various definitions for an acid. The simplest description of an acid is a chemical molecule with one or more hydrogen atoms that, when dissolved in water, gives forth hydronium ions (H3O+).

Because acids are molecular, they do not assume the expanded three-dimensional structures of ionic substances like NaCl and remain single molecules in their pure form. However, when these molecules are dissolved in water, a positively charged anion and a hydronium ion are produced as a result of the chemical connection between the hydrogen atom and the remainder of the molecule breaking. An equation involving chemicals can represent this:

HCl+H2O→H3O++Cl−

In an inorganic acid's formula, the H of the acid is written first. After the acid dissolves, the anion is all that is left of the acid (apart from the H). Although a significant class of chemicals, organic acids are not covered in this article.

Acid Names

Since all acids contain hydrogen, an acid's name is determined by the anion that it is associated with. These anions come in monatomic and polyatomic forms.

Binary acid names (in aqueous form)

An acid that contains hydrogen and another element is referred to as a binary acid. The majority of binary acids have a halogen in them. The prefix hydro- is used to start an acid name, which is then followed by the base name of the anion and the suffix -ic.

Oxyacids name

An oxyacid is an acid made up of three elements: hydrogen, oxygen, and another one. Typically, the third element is a nonmetal.

a) Oxyanions with the -ite end.

The anion's root is followed by the suffix -ous to form the name of the acid. No prefix is present.

b)Oxyanions that end in -ate.

The anion's root and the suffix -ic are used to identify the acid. No prefix is present.

In conclusion

Acids are molecular substances that discharge hydrogen ions.

The two elements hydrogen and the other make up a binary acid.

Hydrogen, oxygen, and another element are all present in oxyacids.

The anion that is bound to the hydrogen provides the basis for the acid's name.

Before baking potatoes that are soft and dehydrated, it is important to give them a good soaking to make them firmer.

For this, a hypotonic solution such as salt water is preferred. Start by filling a large bowl with cold water and adding some salt. The salt will help to draw out moisture from the potatoes, making them firmer and more suitable for baking. Submerge the potatoes in the water and let them soak for at least 30 minutes.

Drain the water and pat the potatoes dry with a paper towel. This will remove any excess moisture and help them to crisp up when baking. You can then season the potatoes as desired and bake them as normal. The soaking process helps to rehydrate the potatoes, making them firmer and more suitable for baking.

The salt also helps to draw out moisture, so that when the potatoes are baked, they will be crisp on the outside and fluffy on the inside. The soaking process is an important step in preparing potatoes for baking, as it helps to make them firmer and more suitable for baking.
