Answer:
Mn is the oxidizing agent.
N is the reducing agent.
Explanation:
Hello!
In this case, according to the undergoing chemical reaction, it is seen that the manganese in KMnO4 has an oxidation state of 7+, in MnSO4 of 2+ and nitrogen in KNO2 is 3+ and in KNO3 is 5+; thus we have the following half-reactions:
Thus, since manganese is undergoing a decrease in the oxidation state, we infer it is the oxidizing agent whereas nitrogen, undergoing an increase in the oxidation state is the reducing agent.
Best regards!
Answer:
3. small sizes and high ionization energies.
Explanation:
Hello,
Ionization energies are always related with the formation of positive ions. On the other hand, electron affinities are the negative ion equivalent, and their use is almost always confined to elements in groups 6 and 7 of the Periodic Table
Small sizes and high ionization energies turn out into great electron affinities since it is easier for an electron to be added to an atom if it is small and it has a high ionization energy to promote the aforesaid addition.
Best regards.
Answer:
mNaNO3 =765g
Explanation:
First, we write the balanced chemical equation representing the chemical reaction that happened between aluminum nitrate and sodium chloride.
Balanced chemical equation:
AL(NO3)3+3NaCl ⟶ 3 NaNO3+AlCl3
According to the equation, each mole of aluminum nitrate requires three moles of sodium chloride. Thus, the required number of moles of sodium chloride is
4 Mol ⋅ 3 = 12mol
Based on the data provided in the table, there were 9 moles of sodium chloride used in the reaction, which was not enough for the entirety of aluminum nitrate to react. So, sodium chloride must have been the limiting reactant.
Therefore, we use the number of moles (n) of sodium chloride to calculate the number of moles of sodium nitrate, which has a 1:1 ratio with sodium chloride.
Number of moles sodium nitrate:
nNaNO3=nNaCl
nNaNO3 = 9 mol
We can also calculate the mass (m) of sodium nitrate that was produced by multiplying its number of moles by its molar mass (MM), 85.00g/mol.
Mass of sodium nitrate produced:
mNaNO3 = nNaNO3 ⋅ MMNaNO3
mNaNO3 = 9 mol ⋅ 85.00 g/mol
mNaNO3 =765g
Given what we know, we can confirm that despite not being able to provide a visual representation, if you were to create one, it would show the atoms in the substance moving with <u>more and more </u>energy over time until vaporization occurred.
<h3>What is vaporization?</h3>
- Vaporization is the changing of a liquid into a gas.
- This is known as a phase change.
- This happens when the atoms receive enough heat energy.
- The heat energy provides the atoms with kinetic energy and causes them to move faster over time.
- When the kinetic energy is enough to rupture the bonds that hold a liquid together, it becomes a gas.
Therefore, given that vaporization is when atoms within a substance gain so much kinetic energy that they are able to rupture the bonds that hold them relatively close together and change into a gas, we can confirm that a visual representation would have to be a diagram showing the increased movement of atoms over time.
