the equation demonstrates a reaction of sodium chloride and fluorine. 2NaCl+F2=2NaF+Cl2. in order for the reaction to proceed, for every two moles of sodium chloride, there must be at least how many mole(s) for fluorine
Answer: You would need 1 mole of Fluorine
Explanation:The equation is already balanced so just looking at the coefficients in the equation we can see that Sodium Chloride (2NaCl) needs two moles for this equation and fluorine (F2) only needs one.
In order for the reaction to proceed, for every two moles of sodium chloride, there must be at least 1 mole for fluorine.
Balanced chemical reaction:2NaCl + F₂ → 2NaF + Cl₂
The reaction given above is balanced. When 2 moles of sodium chloride reacts with 1 mole of fluorine produces 2 moles of sodium fluoride and 1 molecule of chlorine.
Thus, two moles of sodium chloride, there must be at least 1 mole for fluorine.

used in thermometer as it is liquid at room temperature.It is used in batteries , florescent lightit is also used in dental fillingHow is a calorimeter used in this experiment different from the ones used to find the energy content of a snack
Answer:
Kindly check the explanation section.
Explanation:
PS: Note that enough information are not being provided and we do not know the experiment this question is all about. However, some information are provided below which is going to aid in solving when you get access to the main question.
The determination of the heat transferred from one substance to another is one of the important aspect in science. The method in which this heat is being measured is known as calorimetry and the instrument used in this technique is known as the calorimeter.
When the energy content of a snack is needed to be calculated, there is the need use a type of instrument known as bomb calorimeter.
Most of the calorimeters used by students are not so expensive like the used in the industries. Most of these calorimeters operates at a constant pressure while the Bomb Calorimeter operates at constant volume.
Hydrolysis of fructose..
Answer:
Fructose, as glucose, reacts in high-temperature and supercritical water to several products. For the hydrolysis of fructose to 5-(hydroxymethyl)-furfural (HMF), Antal and coworkers [6,24] found a sequence of reactions commencing with the fructofuranose ring and retaining it intact.

Describe the motion of the water molecules as the vapor pressure increases?
Answer: As for vapor pressure being higher at higher temperatures, when the temperature of a liquid is raised, the added energy in the liquid gives the molecules more energy and they have greater ability to escape the liquid phase and go into the gaseous phase.
Explanation:
The motion of the water molecules as the vapor pressure increases is:
The water molecules have greater energyAccording to the movement of the water molecules in a pressurized environment where the vapor and the temperature are increased, there is an increased ability to change from liquid to gas.
As a result of this, the water molecules has greater energy as they are subjected to increased levels of temperature and vapor pressure which makes them have more energy and to be more unstable.

What is the pH of an aqueous solution that has an H+ ion concentration of 0.10 M?
14
10
6
1
Answer:
1
Explanation:
pH = -log[H+] = -log(0.10) = log(1.0 x 10^-1) = 1
The pH scale determines how acidic or basic water is. The pH of an aqueous solution that has an H+ ion concentration of 0.10 M is 1. Therefore, option D is correct.
What is pH ?The pH scale, which previously stood for "potential of hydrogen," is used to describe how acidic or basic an aqueous solution is. The pH values of acidic solutions are typically lower than those of basic or alkaline solutions.
The range is 0 to 14, with 7 representing neutrality. Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7. In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.
A solution's pH is a significant indicator of its chemical composition. The pH can affect how readily available nutrients are, how biological processes work, how bacteria behave, and how chemicals behave.
pH = -log [ H ⁺ ] = -log ( 0.10 )
= log ( 1.0 x 10⁻¹ )
= 1
Thus, The pH of an aqueous solution that has an H+ ion concentration of 0.10 M is 1. Therefore, option D is correct.

Mg + Cu2+ —> Mg2+ + Cu
a) why is this a redox reaction?
b) identify the oxidizing agent. Give reason for your answer
answer any of them you want please
Explanation:
Since the oxidation state of Mg is changed to +2 from 0, it is oxidized. (as it is increased)
Similarly, oxidation state of Cu is changed to 0 from +2, it is reduced. (as it is decreased)
Since oxidation & reduction occur at the same time, it is redox reaction.
As Mg is being oxidized, other one must be the oxidizing agent.
Cu is the oxidizing agent

When the equation

H2O → __H, +
NaOH
is correctly balanced using the smallest whole-number coefficients, what is the coefficient for H2O?
The balanced equation is 2Na + 2H[tex]_2[/tex]O [tex]\rightarrow[/tex] 2NaOH + H[tex]_2[/tex] and the coefficient of H[tex]_2[/tex]O is 2. Stoichiometry represents the number of coefficients.
What is balanced equation?An equation for just a chemical reaction is said to be balanced if both the reactants as well as the products have the same number of atoms and total charge for each component of the reaction. In other words, each sides of both the reaction have an equal balance of mass and charge.
It is typical that balancing chemical formulas for both charge and mass in aqueous solutions. Equal numbers and types of atoms are produced on both aspects of the equation when balancing for mass. When the charge is balanced, there is no net charge on either side of the equation.
The balanced equation can be written as
2Na + 2H[tex]_2[/tex]O = 2NaOH + H[tex]_2[/tex]
The coefficient of H[tex]_2[/tex]O is 2.
Therefore, the balanced equation is 2Na + 2H[tex]_2[/tex]O [tex]\rightarrow[/tex] 2NaOH + H[tex]_2[/tex] and the coefficient of H[tex]_2[/tex]O is 2.
