IF the strong nuclear force affects all particles that are close to each other, What will happen if we add two neutrons to our nucleus with two protons?
A) It will decrease the electromagnetic force in the nucleus
B) It will decrease the strong nuclear force in the nucleus
C) It will increase the strong nuclear force in the nucleus
D) It will increase the electromagnetic force in the nucleus
Answer: it will increase the strong nuclear force in the nucleus
Explanation: Labster
Answer : It will increase the strong nuclear force in the nucleus ( C )
Given that the strong nuclear force affects the particles that are close to each other addition of two neutrons and two protons, will cause an increase in the strong nuclear force found in the nucleus . this is because a Nucleus with two ( 2 ) protons exhibits attractive nuclear force and a repulsive coulomb force. and since the nuclear force does not depend on the charge, the addition of two neutrons the attractive nuclear force will increase
Hence we can conclude that addition of two neutrons to our nucleus with two protons will increase the strong nuclear force in the nucleus.

Do you BELIVE this is how you make Slime?
Slime flows like a liquid, but unlike familiar liquids (e.g., oil, water), its ability to flow, or viscosity, is not constant. So it's a fluid, but not a regular liquid. Scientists call a material that changes viscosity a non-Newtonian fluid. The technical explanation is that slime is a fluid that changes its ability to resist deformation according to shear or tensile stress.
What this means is, when you pour slime or let it ooze through your fingers, it has a low viscosity and flows like a thick liquid. When you squeeze a non-Newtonian slime, like oobleck, or pound it with your fist, it feels hard, like a wet solid. This is because applying stress squeezes the particles in the slime together, making it hard for them to slide against each other.
Most types of slime are also examples of polymers. Polymers are molecules made by linking together chains of subunits.
The specifics of how a type of slime works depends on its chemical composition, but the basic explanation is that chemicals are mixed to form polymers. The polymers act as a net, with molecules sliding against each other.
Two solutions are combined to make classic slime. One is diluted school glue, or polyvinyl alcohol in water. The other solution is borax (Na2B4O7.10H2O) in water.
Borax dissolves in water into sodium ions, Na+, and tetraborate ions.
The tetraborate ions react with water to produce the OH- ion and boric acid:
B4O72-(aq) + 7 H2O 4 H3BO3(aq) + 2 OH-(aq)
Boric acid reacts with water to form borate ions:
H3BO3(aq) + 2 H2O B(OH)4-(aq) + H3O+(aq)
Hydrogen bonds form between the borate ion and the OH groups of the polyvinyl alcohol molecules from the glue, linking them together to form a new polymer: slime.

ca2 -calmodulin-dependent facilitation and ca2 inactivation of ca2 release-activated ca2 channels
This article aims to find that [tex]Ca^{2+}[/tex] occupancy of a site on the extracellular side of the CRAC channel ordinarily potentiates its [tex]Ca^{2+}[/tex] as well as [tex]Na^{+}[/tex] currents, and [tex]Ca^{2+}[/tex] dissociation from this site is responsible for the inactivation of its [tex]Na^{+}[/tex] current.
The most extensively studied of the store-operated ion channels, which are widely expressed and crucial to many vital biological processes, is the [tex]Ca^{2+}[/tex] release-activated [tex]Ca^{2+}[/tex] (CRAC) channel. But little is known about the CRAC channel's molecular makeup or how intracellular or extracellular messengers control it.
It becomes more permeable to monovalent cations with a higher current when extracellular divalent cations are absent, however this monovalent cation current quickly deactivates due to an unidentified mechanism.
Here, it was found that [tex]Ca^{2+}[/tex] occupancy of a site on the extracellular side of the CRAC channel ordinarily potentiates both its [tex]Ca^{2+}[/tex] and [tex]Na^{+}[/tex] currents. [tex]Ca^{2+}[/tex] dissociation from this site, however, results in the inactivation of the channel's [tex]Na^{+}[/tex] current. This [tex]Ca^{2+}[/tex]-dependent potentiation is required for the normal functioning of CRAC channels.

Calculate the concentration of hydrogen ion of a sample of vinegar with pH 6.82
The concentration of hydrogen ion of a sample of vinegar : 1.514 x 10⁻⁷
Further explanationpH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.
So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.
A solution whose value is different by n has a difference in the concentration of H⁺ ion of 10ⁿ.
pH = - log [H⁺]
pH of a sample vinegar = 6.82
The concentration of hydrogen ion :

Put the steps below in the order they are performed in the lab experiment by numbering them 1-7. Use a Bunsen burner to heat and dry the hydrate, repeating until the mass no longer decreases. Measure the final masses of the crucible, cover, and anhydrous salt. Compute differences in masses to find the reactants and products. Measure initial masses of the crucible and cover, with and without the hydrate. Use the numbers of moles to compute the mole ratio. Use stoichiometry to convert these masses to moles. Use the mole ratio to write the hydrate’s formula.
Answer:
1) Measure initial masses of the crucible and cover with and without the hydrate.
2) Use a Bunsen burner to heat and dry the hydrate, repeating until the mass no longer decreases.
3) Measure the final masses of the crucible, cover, and anhydrous salt.
4) Compute differences in masses to find the reactants and products.
5) Use stoichiometry to convert these masses to moles.
6) Use the numbers of moles to compute the mole ratio.
7) Use the mole ratio to write the hydrate’s formula.
Explanation:
A hydrate is any substance that contains water of crystallization. The water of crystallization constitutes part of the mass of the substance. When heated to constant mass, the substance looses its water of crystallization and becomes anhydrous.
The mass of the anhydrous substance is now obtained by weighing again and subtracted from that of the hydrated substance. The masses are converted to moles using stoichiometry and the moles are then used to obtain the formula of the hydrate.

Which of the following most likely requires intermolecular forces?
Answer: The intermolecular forces increase with increasing polarization of bonds. Boiling point increases with molecular weight, and with surface area. The three major types of intermolecular interactions are dipole–dipole interactions, London dispersion forces (these two are often referred to collectively as van der Waals forces), and hydrogen bonds. Intermolecular forces are much weaker than the intramolecular forces of attraction but are important because they determine the physical properties of molecules like their boiling point, melting point, density, and enthalpies of fusion and vaporization.In order from strongest to weakest, the intermolecular forces given in the answer choices are: ion-dipole, hydrogen bonding, dipole-dipole, and Van der Waals forces. Ionic bonding is stronger than any of the given intermolecular forces, but is itself NOT an intermolecular force.

A cylinder of compressed gas has a volume of 350 ml and a pressure of 931 torr. What volume in Liters would the gas occupy if allowed to escape into a balloon at a pressure of 113 kPa if temperature and # of molecules remain constant?
Answer:
[tex]0.384\ \text{L}[/tex]
Explanation:
[tex]P_1[/tex] = Initial pressure = 931 torr = [tex]931\times \dfrac{101.325}{760}=124.12\ \text{kPa}[/tex]
[tex]P_2[/tex] = Final pressure = 113 kPa
[tex]V_1[/tex] = Initial volume = 350 mL
[tex]V_2[/tex] = Final volume
From the Boyle's law we have
[tex]P_1V_1=P_2V_2\\\Rightarrow V_2=\dfrac{P_1V_1}{P_2}\\\Rightarrow V_2=\dfrac{124.12\times 350}{113}\\\Rightarrow V_2=384.44\ \text{mL}=0.384\ \text{L}[/tex]
The volume the gas would occupy is [tex]0.384\ \text{L}[/tex].

Because magnets wear out. Magnetic perpetual machines can never work because magnets eventually wear out. This isn't the reason they don't work. Magnets can lose their magnetism in several ways; Heat them to very high temperatures. Hit them repeatedly with a hammer.
Answer:
It'd never work as the first law of physics is that the law of conservation of energy. It states that energy is often preserved.
