The underground pipe fitting connecting the inlet pipe to a fire hydrant is called the Hydrant Riser.

Fire hydrants with a variety of valves and connection points are seen in many places. In the event of a fire breakout, firefighters locate the fire hydrants, connect their hoses and then pump a large volume of pressurized water to put out the fire. A special pentagonal wrench is used to remove the valve cover of the hydrant. Then after attaching the hoses, the firefighters open the valve for the water to flow.

They usually have a connection point to hook up a fire hose and a nut or bolt to turn on which will start the flow. Every fire hydrant is essentially just an attachment to the main water line. Underneath that connects the hydrant valve through a pipe called a riser. However, normal hydrants don’t change the water pressure or flow in any way. They function as valves so firefighters can utilize the already present pressure in the water pipes. While all of this may sound simple the internal mechanics of a fire hydrant are a little more complex and can vary by region.

Answer:

Coefficient = 1.58

Exponent = - 5

Explanation:

pH = 2.95

Molar concentration = 0.0796M

Ka = [H+]^2 / [HA]

Ka = [H+]^2 / 0.0796

Therefore ;

[H+] = 10^-2.95

[H+] = 0.0011220 = 1.122 × 10^-3

Ka = [H+] / molar concentration

Ka = [1.122 × 10^-3]^2 / 0.0796

Ka = (1.258884 × 10^-6) / 0.0796

Ka = 15.815 × 10^-6

Ka = 1.58 × 10^-5

Coefficient = 1.58

Explanation:

The introduction serves to inform the reader of the basic premises, and then to state the author's thesis, or central idea. A thesis can also be used to point out the subject of each body paragraph. When a thesis essay is applied to this format, the first paragraph typically consists of a narrative hook, followed by a sentence that introduces the general theme, then another sentence narrowing the focus of the one previous. (If the author is using this format for a text-based thesis, then a sentence quoting the text, supporting the essay-writer's claim, would typically go here, along with the name of the text and the name of the author. Example: "In the book Night, Elie Wiesel says..."). After this, the author narrows the discussion of the topic by stating or identifying a problem. Often, an organizational sentence is used here to describe the layout of the paper. Finally, the last sentence of the first paragraph of such an essay would state the thesis the author is trying to prove. The thesis is often linked to a "road map" for the essay, which is basically an embedded outline stating precisely what the three body paragraphs will address and giving the items in the order of the presentation. Not to be confused with an organizational sentence, a thesis merely states "The book Night follows Elie Wiesel's journey from innocence to experience," while an organizational sentence directly states the structure and order of the essay. Basically, the thesis statement should be proven throughout the essay. In each of the three body paragraphs, one or more identified (evidence/fact/etc.) that supports the thesis statement is discussed. And in the conclusion, everything is analyzed and summed up. For example, the conclusion part in an essay about sports: "Sports can bring a bunch of benefits for youth, including general health, together with blood circulation and overall physical stamina improvement. Sport develops and improves people’s physical, social, and organizational skills, which are beneficial in personal and professional life and must always be obtained."

All the listed options (ionic bonds, dipole-dipole interactions, hydrogen bonding, and London dispersion forces) may exist between particles in molecular crystals.

The attractive forces that may exist between particles in molecular crystals include:

Ionic bonds: Ionic compounds, consisting of positively and negatively charged ions, can form crystal structures held together by strong electrostatic attractions.

Dipole-dipole interactions: Molecules with permanent dipole moments can interact with each other through the attraction of their positive and negative ends.

Hydrogen bonding: Hydrogen bonding occurs when a hydrogen atom is bonded to an electronegative atom (such as oxygen, nitrogen, or fluorine) and forms a weak bond with another electronegative atom in a neighboring molecule.

London dispersion forces: Also known as van der Waals forces, these forces arise from temporary fluctuations in electron density, resulting in the creation of temporary dipoles that induce dipole moments in neighboring molecules.

Hence, all of the listed options (ionic bonds, dipole-dipole interactions, hydrogen bonding, and London dispersion forces) may exist between particles in molecular crystals.

Answer:Because you need that certain number and double the number of bread to get the reactants off of the sides

Explanation: 4 bread reactants- 2meat reactants- 2 cheese reactants= 2 products

The reason for the presence of a certain number of reactants on one side is to ensure that the chemical equation is balanced.

In a balanced chemical equation, the number of atoms of each element on the reactant side must be equal to the number of atoms of that element on the product side.

Consider the equation:

\(2H_2 + O_2 - > 2H_2O.\)

This equation represents the reaction of hydrogen gas (\(H_2\)) with oxygen gas (\(O_2\)) to form water (\(H_2O\)).

To balance this equation, double the coefficient in front of \(H_2O\) on the product side, resulting in 4 hydrogen atoms and 2 oxygen atoms on both sides.

Therefore, having a certain number of reactants on one side is necessary to ensure that a chemical equation is balanced, satisfying the law of conservation of mass.

The statement is true. The rate-limiting step in a reaction is the slowest step.

The rate-limiting step in a reaction is the slowest step in the reaction sequence and determines the overall rate of the reaction. This step is generally characterized by having the highest activation energy and is often the step with the lowest concentration of reactants. The rate-limiting step is often the rate-determining step, meaning that the rate of the reaction is dependent on this step. The rate-limiting step is also called the slow step or the rate-controlling step.

Boyle stated that acids taste sour, are corrosive to metals, change the color of litmus to red, and become less acidic when mixed with bases. Acids are substances that release hydrogen ions when dissolved in water.

The sour taste of acids is due to the presence of hydrogen ions. When acids come in contact with metals, they corrode them by reacting with the metal to form metal salts and hydrogen gas. Litmus is a natural dye that is used to indicate the acidity or basicity of a substance. Acids turn litmus paper red, while bases turn it blue. When acids are mixed with bases, they neutralize each other, and the resulting solution becomes less acidic.
Boyle stated that acids taste sour, are corrosive to metals, change the color of litmus to red, and become less acidic when mixed with bases. Acids are compounds that release hydrogen ions (H+) when dissolved in water, and litmus is an indicator that changes color based on the acidity or basicity of a solution. Mixing an acid with a base results in a neutralization reaction, producing water and a salt, thereby reducing the acidic properties.

To prepare a buffer solution by the reaction of a weak base with a strong acid, the weak base must be the limiting reactant.

A buffer solution is a solution that has the capacity to keep the pH of a solution relatively constant despite the addition of other substances that typically affect the pH of the solution. A buffer solution is made up of a weak acid and its corresponding conjugate base or a weak base and its corresponding conjugate acid. The solution can be prepared by reacting a weak acid with its corresponding conjugate base or by reacting a weak base with its corresponding conjugate acid.

To prepare a buffer solution by the reaction of a weak base with a strong acid, the weak base must be the limiting reactant. When the weak base reacts with the strong acid, it produces salt and water. The salt formed will be the conjugate acid of the weak base. The resulting solution will contain both the weak base and its conjugate acid, which act as a buffer solution. Hence, the limiting reactant in preparing a buffer solution by the reaction of a weak base with a strong acid is the weak base.

The balanced chemical equation of the reaction is;

From the balanced chemical equation;

3 moles of H₂ reacted with 1 mole of N₂ to produce 2 moles of NH₃

Molar mass of H₂ = 2.016 g/mol

Molar mass of N₂ = 28.0134 g/mol

Molar mass of NH₃ = 17.031 g/mol

Convert mole to gram using the formula;

For 1 mole N₂

For 3 moles H₂

For 2 moles NH₃

We can now calculate, the mass of NH₃ that can be produced from 79.8 grams of H₂ as follows:

From the balanced equation we can say;

6.048 grams H₂ → 34.062 grams NH₃

∴ 79.8 grams H₂ → x grams NH₃

Therefore, 449.4 grams of Ammonia is produced if you started with 79.8 grams of Hydrogen.
