Thank you ☺️☺️

Answer:

When an atom or group of atoms in a molecule is replaced by another atom or group of atoms, such chemical reaction is called displacement reaction. Displacement reaction is of two types. They are:

When an atom in a molecule is replaced by another atom, such chemical reaction is called single displacement reaction.

For example:

Zinc + Hydrochloric acid → Zinc Chloride + Hydrogen

Zn + 2HCI → ZnCI₂ + H₂

Here, Zn is more reactive than H₂. So, Zn displaces H from the compound HCI.

A chemical reaction in which the molecules of the reactants get decomposed and exchange their corresponding ions to give new products is called a double displacement reaction.

For example:

AgNO₃ + NaCI → NaNO₃ + AgCI

Answer:

atoms of the same element that have different masses due to their

varying numbers of neutrons

Explanation:

The mass number of an atom is the  sum of number of protons and number of neutrons. Whereas, charge is acquired by the lose or gain of electrons.

The atomic mass describes how much an atom weighs. The mass of an atom is usually take as relative mass where the mass of an atom is determined relative to the mass of carbon -12.

Mass number describes the sum of number of protons  and neutrons.  The mass of an atom is mainly contributed by the nucleus thats why take the ,mass number as its mass.

An atom gains positive charge when it loses one or more electron. For example hydrogen with 1 proton and no neutrons will lose its one electron and acquire a positive charge.

When an atom gains an electron it acquire a negative charge. Consider oxygen where 8 neutron and 8 electrons  (6 valence electrons) are there with a mass of 16 g/mol. It acquires 2 units of negative charge by gaining two electron. Since it needs two ore electron to attain octet.

Similarly a nitrogen atom with mass of 14 g/mol and 5 valence electrons acquire a -3 charge since it need 3 more electron to attain octet.

Based on the given options, Compound B would react the fastest, Compound C would react the slowest, and Compound A would have intermediate reactivity.

Based on the given reaction, bromination, the reactivity of the compounds can be determined based on the presence of electron-donating or electron-withdrawing groups.

Compound A: C(CH₃)₃

Compound B: CN

Compound C: OH

In bromination reactions, electron-donating groups increase the reactivity, while electron-withdrawing groups decrease the reactivity.

Fastest reaction: Compound B (CN)

The presence of a cyano group (-CN) in Compound B is an electron-withdrawing group, which increases the reactivity towards bromination. Therefore, Compound B would react the fastest.

Slowest reaction: Compound C (OH)

The presence of a hydroxyl group (-OH) in Compound C is an electron-donating group, which decreases the reactivity towards bromination. Therefore, Compound C would react the slowest.

Compound A (C(CH₃)₃) does not have any functional groups that significantly influence the reactivity towards bromination. It may have intermediate reactivity.

So, based on the given options, Compound B would react the fastest, Compound C would react the slowest, and Compound A would have intermediate reactivity.

The question requires us to calculate the mass, in grams, contained in 5.26 x 10^-4 mol of HC2H3O2.

To solve this question, first we need to calculate the molar mass of the compound, considering the number of atoms of each element, and then relate the value obtained with the number of moles given (5.26 x 10^-4 mol).

First, to calculate the molar mass of the compound, let's consider the following atomic masses:

atomic mass of C = 12.01 u

atomic mass of H = 1.007 u

atomic mass of O = 15.99 u

Next, we calculate the molar mass. To do that, we need to consider the number of atoms of each element: according to the chemical formula, there are 2 atoms of C, 4 atoms of H and 2 atoms of O:

molar mass (C2H4O2) = (2 * 12.01) + (4 * 1.007) + (2 * 15.99) = 60.03 g/mol

Now, we know that there are 60.03 g for each mol of the compound. With that information, we can estabilish the following relation to calculate the mass contained in 5.26 x 10^-4 mol of the compound:

1 mol --------------------- 60.03 g

5.26 x 10^-4 mol ----- x

Solving for x, we have:

Therefore, there are 0.03158 g of HC2H3O2 in 5.26 x 10^-4 mol of this compound.

To determine the volume of a 2.00 M Pb(NO3)2 solution that will react with 50.0 mL of a 1.50 M KCl solution, we need to use stoichiometry and the balanced chemical equation. And it is 18.75 mL of a 2.00 M Pb(NO3)2 solution.

Based on the balanced chemical equation:

Pb(NO3)2 + 2KCl → PbCl2 + 2KNO3,

the stoichiometric ratio between Pb(NO3)2 and KCl is 1:2.

Given that the volume of the KCl solution is 50.0 mL and its concentration is 1.50 M, we can calculate the moles of KCl present. Using the concentration and volume, we find that there are 0.075 moles of KCl. Since the stoichiometric ratio is 1:2, the number of moles of Pb(NO3)2 required is half of that, which is 0.0375 moles. Using the concentration of the Pb(NO3)2 solution (2.00 M), we can calculate the volume by dividing the moles by the concentration. This gives us a volume of 18.75 mL. Therefore, 18.75 mL of a 2.00 M Pb(NO3)2 solution will react with 50.0 mL of a 1.50 M KCl solution based on the stoichiometry of the balanced chemical equation.

The ornamental casting contains approximately 9.5 × 10^23 atoms of silver and 19 × 10^23 atoms of gold.

To determine the composition of the ornamental casting after the loss of atoms during the casting process, we need to calculate the remaining number of atoms for each element.Given:

Number of silver atoms = 10 × 10^23 atoms

Number of gold atoms = 20 × 10^23 atoms

Percentage of atoms lost = 5.0%

First, we calculate the number of lost atoms for each element:

Number of lost silver atoms = 5.0% of 10 × 10^23 = (5.0/100) * 10 × 10^23 = 0.5 × 10^23 atoms

Number of lost gold atoms = 5.0% of 20 × 10^23 = (5.0/100) * 20 × 10^23 = 1.0 × 10^23 atoms

Next, we subtract the lost atoms from the original number of atoms to determine the remaining atoms for each element:

Remaining number of silver atoms = 10 × 10^23 - 0.5 × 10^23 = 9.5 × 10^23 atoms

Remaining number of gold atoms = 20 × 10^23 - 1.0 × 10^23 = 19 × 10^23 atoms

Therefore, the ornamental casting contains approximately 9.5 × 10^23 atoms of silver and 19 × 10^23 atoms of gold.

The salts whose aqueous solutions will be acidic, basic, or neutral are as follows:

The acidity or basicity of a salt solution depends on the acid-base properties of the ions produced when the salt dissolves in water. In general, if the cation of the salt is the conjugate acid of a weak base and/or the anion of the salt is the conjugate base of a weak acid, then the solution will be acidic. If the cation of the salt is the conjugate base of a strong acid and/or the anion of the salt is the conjugate acid of a strong base, then the solution will be basic. If both the cation and anion are derived from strong acids and bases, then the solution will be neutral.

In the case of CH₃NH₃I, the CH₃NH₃⁺ cation is the conjugate acid of a weak base (methylamine), so it will hydrolyze and produce H+ ions, making the solution acidic. For (C₂H₅)₂NH₂I, the (C₂H₅)₂NH₂⁺ cation is the conjugate base of a weak acid (diethylamine), so it will hydrolyze and produce OH⁻ ions, making the solution basic. LiClO4 and Ba(F₃CCOO)₂ both produce ions derived from strong acids and bases, so their solutions will be neutral. KCHCl₂CO₂ produces the CHCl₂CO₂⁻ anion, which is the conjugate base of a weak acid (dichloroacetic acid), so it will hydrolyze and produce OH- ions, making the solution basic.
