Answers
When the products have lower enthalpy than the reactants, the reaction tends to be spontaneous.
Spontaneous reactions are those that occur without any external input of energy. In general, spontaneous reactions tend to occur when the products have lower enthalpy than the reactants.
It is not necessarily true that a reaction will be spontaneous just because the products have lower enthalpy than the reactants. Other factors, such as the entropy of the reactants and products, can also affect the spontaneity of a reaction.
So, to summarize: When the products have lower enthalpy than the reactants, the reaction tends to be spontaneous. However, the spontaneity of a reaction also depends on other factors, such as the entropy of the reactants and products.

The correct answer is exergonic; catalyzed for Curve B and exergonic; uncatalyzed for Curve A.
Curve A and Curve B represent the same chemical reaction under two different conditions. Curve B represents a reaction catalyzed by an enzyme, which speeds up the reaction rate.
This is an exergonic reaction, meaning it releases energy.
Enzymes work by lowering the activation energy needed for the reaction to occur, thus increasing the rate at which the reaction takes place. In contrast, Curve A represents the same exergonic reaction but in an uncatalyzed state, meaning no enzyme is present to accelerate the process.

you have a compound with the following chemical formula: fe2o3 what is the charge on the iron cation
Answers
The charge on the iron cation in the compound with the chemical formula Fe2O3 is +3.
To determine this, follow these steps:
1. Identify the elements in the formula: Fe represents iron, and O represents oxygen.
2. Determine the charge of the oxygen anion. Oxygen typically has a charge of -2.
3. Balance the charges in the compound. In this case, there are two iron cations (Fe) and three oxygen anions (O). The total charge of the oxygen anions is -6 (3 x -2 = -6).
4. To balance the charges, the iron cations must have a total charge of +6. Since there are two iron cations, each must have a charge of +3 (6 ÷ 2 = 3).
So, the charge on the iron cation in Fe2O3 is +3.

What are the major disadvantages of using ozone instead of chlorine to disinfect water? O Ozonation is more expensive than chlorination and ozone leaves an odor in the water O Ozonation causes trihalomethane formation and leaves an odor in the treated water O Ozone decomposes quickly and does not provide long-term protection against possible contamination as the water is piped through a municipal distribution system O Ozonation causes trihalomethane formation and is more expensive than chlorination
Answers
The major disadvantage is - Ozone decomposes quickly and does not provide long-term protection against possible contamination as the water is piped through a municipal distribution system.
The gas ozone (O3) is unstable. As a result, it breaks down quickly, oxidizing any organic impurities present in the water including bacteria, viruses, and germs, but because it is a gas, it leaves the water after the oxidation is complete. Therefore, when the ozone started to disintegrate at first, the water may have various additional contaminants that mix with it as it travels through the municipal distribution system. Water carries through the new pollutants from the pipes. Ozone therefore has no long-term effect.
Chlorination produces trihalomethane, not ozonation, hence the expansiveness of ozone is dependent on the impurity of the water. Trihalomethane is produced by chlorination, not ozonation. Although ozone as a gas has a faint odor, when it is combined with water, it oxidizes the pollutant and breaks down, leaving no ozone in the water. Therefore, water does not smell like ozone.

The elements are arranged in Mendeleev's periodic table in a tabular format, increasing atomic mass order to represent similarities and patterns in the behavior of the elements.
In the beginning, Mendeleev organized the elements in ascending order of atomic weight. Nearby elements with related characteristics are positioned. In the same horizontal row, elements are located that have comparable characteristics.
The gaps that Mendeleev left in his table were one of its distinctive features. He not only anticipated the existence of yet-undiscovered elements within those locations, but also their atomic weights and other properties.

a. In the complete reaction of 22.99 g of sodium
with 35.45 g of chlorine, what mass of sodium
chloride is formed?
Answers
Answer : 58.44 g
Further explanationThe reaction
\(\tt Na+Cl\Rightarrow NaCl\)
mole ratio :
Na : Cl : NaCl = 1 : 1 : 1
Molar mass of Na : 22,989769 g/mol = 22.99 g/mol
Molar mass of Cl : 35,453 g/mol= 35.45 g/mol
Molar mass of NaCl : 58,44 g/mol
Let's check the mol for reactant (Na and Cl) and product(NaCl)
mol of Na :\(\tt mol=\dfrac{22.99}{22.99}=1\)
mol of Cl :\(\tt mol=\dfrac{35.45}{35.45}=1\)
Then the reactants are completed reacting because it matches the mole ratio, which is 1: 1
so that the mole of the product can be determined from the mol Na or Cl, which is 1
mass of NaCl :\(\tt =\dfrac{mol~NaCl}{mol~Na}\times MW~NaCl\\\\=\dfrac{1}{1}\times 58.44\\\\=\boxed{\bold{58.44~g}}\)

the anion no2- is expected to be a stronger base than the anion no3-. True or false
Answers
False. The anion NO2- is not expected to be a stronger base than the anion NO3-.
To determine the relative strength of bases, we can examine their conjugate acids. The stronger the acid, the weaker its conjugate base. In this case, we are comparing the conjugate bases of nitrous acid (HNO2) and nitric acid (HNO3), which are NO2- and NO3-, respectively.
Nitrous acid (HNO2) is a weak acid, meaning it does not fully dissociate in water. It partially ionizes to form H+ and NO2-. On the other hand, nitric acid (HNO3) is a strong acid that readily dissociates in water to form H+ and NO3-.
The strength of an acid is determined by its ability to donate protons (H+ ions). Since nitric acid (HNO3) is a stronger acid than nitrous acid (HNO2), it has a greater tendency to donate protons. Consequently, the conjugate base of nitric acid (NO3-) is weaker than the conjugate base of nitrous acid (NO2-).
Therefore, the statement that the anion NO2- is expected to be a stronger base than the anion NO3- is false. NO3- is the stronger base compared to NO2-.
