An electron is released from rest in a uniform electric field of magnitude 2.0×10 4
N/C. Calculate the acceleration of the electron. ( Ignore gravitation.)
When an electron is released from rest in a uniform electric field of magnitude 2.0×10^4N/C the acceleration of the electron is 3.15x10^15m/s2.
Given the magnitude of electric field (E) = 2.0x10^4N/C
The magnitude of the force acting on the electron is F = qE where E is the magnitude of the electric field at its location and q is the charge of electron. q= 1.602x10-19C
From Newton's second law the acceleration of the electron: F = ma
where m is the mass of electron = 9.11x10-31kg
By comparing above two equations we have ma = qE
a = qxE/m = 1.602x10-19 x 2.0x10^4/9.11x10-31 = 3.51x10^15m/s2

Review to make them an isotonic solution a hypotonic solution such as tap water a hypertonic solution made with distilled water and a tablespoon of salt a hypertonic solution such as distilled wate
If you are going to bake potatoes, and your potatoes are soft and dehydrated, they can be soaked in hypotonic solution in a more firm before baking.
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.

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?
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.

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.

write short note about acid nomenclature
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.

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.

New techniques also emerge during the synthesis that can change the approach. Retrosynthetic analysis is a concept that was developed by Corey starting in the 1960s.
