Answer:
Water separates the two reactants into two layers, stopping the reaction.
Explanation:
Maleic anhydride can and will react with water.
The reaction between maleic anhydride and anthracene is a Diels Alder reaction. This type of reaction is a cycloaddition reaction.
What is Diels Alder reaction?The Diels Alder reaction is a member of a class of reactions called cycloadditions. This reaction involves three pi bonds, two from the diene and one from the dienophile in a concerted reaction to give a six-membered ring.
Since this reaction involves four pi electrons in the diene and two pi electrons from the dienophile, it is sometimes referred to as a 4+2 cycloaddition.
The presence of electron donating groups on the diene and the electron withdrawing groups on the dienophile favors normal Diels Alder reactions. The reaction involves the formation of new σ bonds which are energetically more stable than π bonds.
Anthracene can react with water, breaking the center ring. Maleic anhydride can react with water, opening its ring. The reactants get seperated into two layers by water and thereby stops the reaction.

what is meant by dative covalent bond
A coordinate covalent bond, also known as a dative bond, dipolar bond, or coordinate bond is a kind of two-center, two-electron covalent bond in which the two electrons derive from the same atom. The bonding of metal ions to ligands involves this kind of interaction. This type of interaction is central to Lewis theory.

the mass number for an atom is numerically equal to which quantity
Answer:
The mass number of an atom is equal to the number of protons plus the number of neutrons that it contains. In other words, the number of neutrons in an atom is its mass number minus its atomic number.
Explanation:
protons
The mass number of an atom is its total number of protons and neutrons. Atoms of different elements usually have different mass numbers , but they can be the same. For example, the mass number of argon atoms and calcium atoms can both be 40.

Which element in Fe(NO3) is a metal?
O
N
Fe
Answer:
Explanation:
Most periodic tables have a staircase thick line on their right side. This line separates the metals from the non metals.
O (oxygen) and N (nitrogen) are on the right side of the staircase.
Fe is on the left.
Those elements on the right side of the staircase are non metals.
Those elements on the left of the staircase are metals, so Fe is a metal.

A 0.8612-g sample of a mixture of NaBr, NaI, and NaNO3 was analyzed by adding AgNO3 and precipitating a 1.0186-g mixture of AgBrand AgI. The precipitate was then heated in a stream of Cl2, convertingit to 0.7125 g of AgCl. Calculate the %w/w NaNO3 in the sample.
Percentage by weight of the NaNO₃, is given by the ratio of the mass of NaNO₃ to the mass of the sample
The percentage by weight of NaNO₃ in the sample is approximately 30.713 %
Reason:
Given parameters are;
Mass of sample of NaBr, NaI, and NaNO₃ mixture = 0.8612 g
Mass of AgNO₃ and AgI formed = 1.0186
Mass of AgCl formed = 0.7125
Required:
Percentage by weight of NaNO₃ in the sample
Solution:
Let A represent NaBr, let B represent NaI, and let C represent NaNO₃, we have;
Equation 1 A + B + C = 0.8612
The addition of AgNO₃, precipitates 1.0186 g mixture of AgBr and AgI, therefore, we have;
[tex]A \cdot\left(\dfrac{Molar \ mass \ of \ AgBr}{Molar \ mass \ of \ NaBr} \right) + B \cdot \left(\dfrac{Molar \ mass \ of \ AgI}{Molar \ mass \ of \ NaI} \right) = 1.0186[/tex]
Molar mass of AgBr = 187.77 g/mol
Molar mass of NaBr = 102.894 g/mol
Molar mass of AgI = 234.77 g/mol
Molar mass of NaI = 149.89 g/mol
Which gives;
Equation 2 [tex]A \cdot\left(\dfrac{187.77}{102.894} \right) + B \cdot \left(\dfrac{234.77}{149.89} \right) = 1.0186[/tex]
The forming of the precipitate by passing the compounds through a stream of chlorine gives;
[tex]A \cdot\left(\dfrac{Molar \ mass \ of \ AgCl}{Molar \ mass \ of \ NaBr} \right) + B \cdot \left(\dfrac{Molar \ mass \ of \ AgCl}{Molar \ mass \ of \ NaI} \right) = 0.7125[/tex]
Molar mass of AgCl = 143.32 g/mol
Therefore, we get;
Equation 3 [tex]A \cdot\left(\dfrac{143.32}{102.894} \right) + B \cdot \left(\dfrac{143.32}{149.89} \right) = 0.7125[/tex]
Solving equation (2), and (3) gives;
A ≈ 0.3252 g, B ≈ 0.2715 g
Plugging in the values of A, and B in equation (1), gives;
0.3252 + 0.2715 + C = 0.8612
C = 0.8612 - (0.3252 + 0.2715) ≈ 0.2645
The mass of NaNO₃ in the mixture, C ≈ 0.2645
[tex]The \ percent \ by \ weight \ of \ NaNO_3 = \dfrac{0.2645}{0.8612} \times 100 \approx \underline{30.713 \%}[/tex]
