Rutherford conducted a famous experiment called the gold foil experiment.

He took a skinny sheet of gold foil. He used a special gadget to shoot alpha particles undoubtedly charged debris on the gold foil. most debris passed straight thru the foil like the foil was now not there. They bombarded very skinny sheets of gold foil with fast-shifting alpha debris. Rutherford found that a small percent of alpha debris had been deflected at massive angles, which could be explained by using an atom with a very small, dense, definitely-charged nucleus at its middle.

Rutherford designed an experiment to apply the alpha particles emitted via a radioactive element as probes to the unseen global atomic structure. If Thomson changed into correct, the beam might move immediately through the gold foil. most of the beams went via the foil, however, some have been deflected. Ernest Rutherford postulated the nuclear structure of the atom, determined alpha and beta rays, and proposed legal guidelines for radioactive decay. In 1911, Rutherford, Marsden, and Geiger determined the dense atomic nucleus by bombarding a thin gold sheet with the alpha particles emitted through radium.

In steps 11-14, each test tube is compared to the control test tube (#1). In these steps, the colors of each test tube are to be compared with the control test tube. One must determine whether the system has shifted towards reactants or products due to the changes.

Let us discuss how each change affects the equilibrium in terms of Le Chatelier's principle:11. A small amount of sodium bicarbonate (NaHCO3) was added to the system. The solution will turn cloudy, and a slight greenish-yellow color may appear in the test tube. Adding a base to an equilibrium system results in a shift towards the reactants. Since the solution is more acidic than basic, it will absorb the base and shift the equilibrium to the right. This change did not affect the equilibrium of the system.12.  A small amount of hydrochloric acid (HCl) was added to the system. A deep yellow color should appear in the test tube. Adding an acid to an equilibrium system results in a shift towards the products. Since the solution is more basic than acidic, it will absorb the acid and shift the equilibrium to the right. This change affects the equilibrium by increasing the amount of NO2 in the solution.13.  A small amount of copper (II) sulfate (CuSO4) was added to the system. The solution will turn greenish-blue. Adding a catalyst to an equilibrium system does not affect the equilibrium of the system. This change did not affect the equilibrium of the system.14.  A small amount of sodium nitrite (NaNO2) was added to the system. The solution will turn yellow-brown. Adding a product to an equilibrium system results in a shift towards the reactants. This change affects the equilibrium by decreasing the amount of NO2 in the solution. In conclusion, for the forward reaction, the system is exothermic.

The equilibrium will shift to the right, producing more NH₃(g).

When the volume is decreased at a constant temperature, the pressure initially rises. By lowering the pressure, the system will find equilibrium again, and in order to do so, the equilibrium must be moved to the side with the fewest moles of gas. Compared to the reactant side, which has four moles of gas, the product side has just two moles. The equilibrium will move to the right as the volume is decreased (with an initial increase in pressure).

Answer/Explanation:

[1] The difference in electron movement between ionic and covalent bonding is ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms.

[2] One way you can predict if a bond would be ionic or covalent based on the location of the elements on the periodic table is  to look how far apart the two atoms forming the bonds are in the periodic table. If one atom is on the far left (Group 1 or 2) and the other is on the far right (Group 5, 6, or 7), then the atoms will have large differences in EN and will form an ionic bond.

[3] You can predict if a bond would be ionic or covalent based on electronegativity is If the electronegativity difference is less than 0.5, then the bond is nonpolar covalent. If the ΔEN is between 1.6 and 2.0 and if a metal is involved, then the bond is considered ionic. If only nonmetals are involved, the bond is considered polar covalent.

[4] In Order for bonds to break in reactants Molecules must collide in order to react. In order to effectively initiate a reaction, collisions must be sufficiently energetic (kinetic energy) to break chemical bonds.

[5]  The height of an object affect the amount of gravitational potential energy it has by gravitational potential energy (P.E) depends on the mass of the body and the height at which it travels, the two quantities will therefore dictate the work done on the object which is eventually the same as  magnitude of the gravitational potential energy P.E. It is assumed that gravitational pull acts toward the earth surface. The more the object move upward the more the work is done on the object to pull it down. We can have different masses of object at different heights, but gravitational field strength will always remain constant on earth.Since the gravitational potential energy P.E depend on the mass of the body and the height at which it travels, the two quantities will therefore dictate the work done on the object which is eventually the same as  magnitude of the gravitational potential energy P.E.

[6] Kinetic energy is a form of energy that an object or a particle has by reason of its motion.Kinetic energy is a property of a moving object or particle and depends not only on its motion but also on its mass.

[7] The connection between kinetic energy and temperature is the relationship between temperature and kinetic energy is that the higher the temperature, the more kinetic energy there is. As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container.

Explanation:

1.A physical property is an aspect of matter that can be seen or measured without changing its chemical composition. Examples of physical properties include color, molecular weight, and volume.

A chemical property is observed only by changing the chemical identity of a substance. In other words, the only way to detect a chemical is to perform a chemical reaction.

2.This property measures the ability of chemical change. Examples of chemical properties are reactivity, flammability, and oxidation state.

The physical properties of a substance do not involve any chemical reaction. These include density, color, mass, hardness, freezing points, electrical properties, and the like.

Chemical properties include the reaction of chemicals with other substances. These reactions lead to the disappearance of the raw material and the appearance of new materials that have different physical and chemical properties.

3.Chemical properties can be compared to physical properties; On the contrary, they are recognizable without changing the structure of matter. However, for many properties in the field of physical chemistry and other disciplines at the boundary between chemistry and physics, the distinction can be a matter for the researcher's point of view. The properties of materials, both physical and chemical, can be seen as metaphysical; This means that it is secondary to the principle of tangible reality. Multiple metamorphic layers are also possible.

Explanation:

If the reaction has a 87% yield, then it will produce 1392 grams of CO₂.

The limiting reactant, also known as the limiting reagent, is a substance in a chemical reaction that is fully consumed before the other reactants and determines the maximum amount of product that can be formed. In a reaction mixture, the limiting reactant is the one that runs out first and therefore limits the amount of product that can be formed.

The amount of limiting reactant in a reaction determines the amount of product that can be formed, and the amount of other reactants will be left over. If the reaction yields 87%, it will generate 1600 x 87% = 1392 grams of CO2.

Sodium bicarbonate may increase blood pressure. Avoid sodium bicarbonate if you already have high blood pressure.

Excess baking soda is deadly. This is due to the high sodium content of the powder. When someone takes too much sodium bicarbonate, the body tries to restore proper salt levels by pushing water into the digestive tract, which causes vomiting and diarrhea. Divide the change in mass by the initial mass of the substance.

This calculation shows how much the original mass has changed. Low bicarbonate levels in the blood can lead to a condition called metabolic acidosis, or too much acid in the body. A variety of conditions can cause metabolic acidosis including diarrhea kidney disease and liver failure. The chemical formula for sodium bicarbonate is NaHCO3. When heated above about 80°C, it begins to decompose producing sodium carbonate water, and carbon dioxide.

Answer:  A

Explanation:

2.5 moles of Al₂O₃ can form from 5.0 moles of Al.

In the field of chemistry, moles serve as a fundamental unit of measurement to quantify the amount of a given substance. To be precise, one mole is equivalent to the number of elementary entities - atoms, molecules or ions - present in 12 grams of carbon-12. This definition helps scientists accurately measure and express quantities in their experiments and research endeavors.

Equation:

4 Al + 3 O₂ → 2 Al₂O₃

From the balanced equation, we can see that 4 moles of Al reacts with 3 moles of O₂ to form 2 moles of Al₂O₃.

So, for every 4 moles of Al used in the reaction, 2 moles of Al₂O₃ are produced. We can use this ratio to calculate the moles of Al₂O₃ that can be formed from 5.0 moles of Al:

Moles of Al₂O₃ = (5.0 mol Al) x (2 mol Al₂O₃ / 4 mol Al) = 2.5 mol Al₂O₃
