An acute impact is a detrimental reaction to an exposure that occurs immediately or quickly.
A chronic impact is a long-term/permanent result of a single dosage or repeated lesser doses of a toxic drug.
What type of effects occur immediately following a chemical exposure?Acute (short-term) effects appear immediately or shortly after chemical exposure. They might be mild, such as nose or throat discomfort, or serious, such as eye damage or passing out from chemical fumes. All of these effects have one thing in common: they occur immediately.
What are the types of chemical exposure?The many methods in which a person might come into contact with dangerous substances are referred to as exposure routes. There are three primary routes of exposure: inhalation, ingestion, and skin contact.

The force delivered perpendicularly to an object's surface per unit area across which that force would be dispersed is known as pressure. In comparison to the surrounding pressure, gauge pressure defines the pressure. The units was using to express pressure vary.
Calculation of force:
Force excerted by the Ar atoms, (F) = Change in momentum for one Ar atom 7 / unit time × number of atom
F = 2mv /1s × number of atoms.

Q4. When 20 g of salt is added to a beaker containing 100 g of water, the salt dissolves and seems to disappear as a solution is formed. A) What is the mass now? B) Explain your answer.
The mass of the solution is equal to 120 g. As the salt dissolves in water so it disappears when the solution is formed.
Why does salt dissolve in water?The salt dissolves in water at the molecular level, due to electrical charges. Due to this fact that both water and salt are polar, with positive and negative charges on opposite sides of their molecule. The bonds in salt are ionic and have an electrical charge.
Likewise, a water molecule is also ionic in nature, but the covalent bonds are present with two hydrogen atoms and one oxygen atom, which has a negative charge. The salt dissolves because the covalent bonds of water molecules are stronger than the ionic bonds present in the salt molecules.
The mass of the given salt is equal to 20 g while the mass of water is 100g. The total mass of the solution is equal to the sum of the mass of the solute and the mass of the solvent. Therefore, the mass of the solution will be equal to 120 grams whether the salt gets dissolved in water and get disappeared.

Americium–241 decays into neptunium–237. which correctly describes this process of radioactive decay? an unstable nucleus decays into a more stable nucleus. energy in the nucleus is converted into mass. the strong nuclear force splits the nucleus apart. the atom loses four protons.
When Americium–241 decays into neptunium–237, an unstable nucleus decays into a more stable nucleus.
What is Radioactive decay?
Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay (α-decay), beta decay (β-decay), and gamma decay (γ-decay), all of which involve emitting one or more particles. The weak force is the mechanism that is responsible for beta decay, while the other two are governed by the electromagnetism and nuclear force. A fourth type of common decay is Electron Capture, in which an unstable nucleus captures an inner electron from one of the electron shells. The loss of that electron from the shell results in a cascade of electrons dropping down to that lower shell, resulting in emission of discrete X-rays from the transitions. A common example is Iodine-125 commonly used in medical settings.Radioactive decay is a stochastic (i.e. random) process at the level of single atoms. According to quantum theory, it is impossible to predict when a particular atom will decay, regardless of how long the atom has existed. However, for a significant number of identical atoms, the overall decay rate can be expressed as a decay constant or as half-life. The half-lives of radioactive atoms have a huge range; from nearly instantaneous to far longer than the age of the universe.The decaying nucleus is called the parent radionuclide (or parent radioisotope), and the process produces at least one daughter nuclide.Except for gamma decay or internal conversion from a nuclear excited state, the decay is a nuclear transmutation resulting in a daughter containing a different number of protons or neutrons (or both). When the number of protons changes, an atom of a different chemical element is created.To learn more about Radioactive decay: https://brainly.com/question/1770619

How can we increase the rate of collisions between the reactants in this reaction? mg 2hcl → mgcl2 h2
The frequency of collisions between the two reactants increases as the concentration of the reactants increases. When collisions happen, they don't always cause a reaction (atoms misaligned or insufficient energy, etc.). Higher concentrations result in more collisions and reaction opportunities.
Increasing a reactant's surface area increases the frequency of collisions and thus the reaction rate. The surface area of several smaller particles is greater than that of a single large particle. The greater the available surface area for particles to collide, the faster the reaction will occur.
How does concentration affect the rate of collisions between reactants?Thus, we can conclude that by increasing the concentration of Mg in the reaction mixture we increase the rate of collisions between the reactants in this reaction.

The pH of the solution at 25 degree celsius of 1.3 × 10⁻⁶ moles of a sample of Sr(OH)₂ is 10.02.
How do we calculate pH?The pH of any solution gives an idea about the acidic and basic nature of the solution and the equation of pH will be represented as:
pH + pOH = 14
Given that,
Moles of Sr(OH)₂ = 1.3 × 10⁻⁶ mol
Volume of solution = 25mL = 0.025L
The concentration of Sr(OH)₂ in terms of molarity = 1.3×10⁻⁶/0.025
= 5.2×10¯⁵M
Dissociation of Sr(OH)₂ takes place as:
Sr(OH)₂ → Sr²⁺ + 2OH⁻
From the stoichiometry of the reaction 1 mole of Sr(OH)₂ produces 2 moles of OH⁻.
Given that the base is a strong base and that it entirely dissociates into its ions, the hydroxide ion concentration is 5.2×10¯⁵×2 = 1.04×10¯⁴ M.
pOH = -log[OH⁻]
pOH = -log(1.04×10¯⁴)
pOH = 3.98

C3Hg has a higher lower boiling point than C₂H6-
Answer:
C₃H₈ has a higher boiling point than C₂H₆
Explanation:
The boiling point is the temperature at which the intermolecular forces between molecules are overcome and the state of the substance changes from liquid to gas.
Since these are both hydrocarbons (molecules containing just carbon and hydrogen), the strength of their intermolecular bonds should be the same. However, since C₃H₈ is larger, it can form more of these intermolecular bonds. Thus, it takes more energy and a higher temperature to overcome the increased amount of forces.

The volume of benzaldehyde (ml) is 304.65 mL, if the density of benzaldehyde is 1.045 g/ml and having 3 mol.
Given,
Moles of benzaldehyde = 3 mol
Density of benzaldehyde = 1.045g/mol
Molar mass of benzaldehyde = 106.12 g/mol.
As we know that,
Moles can be calculated as
Moles = Given mass/ molar mass
3 = Given mass/ 106.12
Given mass = 318.36g.
The mass of benzaldehyde is 318.36g.
Now,
Density = mass/ Volume
1.045 = 318.16/ Volume
Volume = 318.36/1.045
Volume = 304.65 mL.
Thus, we find that the volume of benzaldehyde is
304.65 mL.
