The half reaction that should occur at the anode during electrolysis of an aqueous potassium bromide solution is formation of bromine from its ions.
As we know, that anions are negatively charged anions. So, these get oxidised to get stable state at anode. Thus, negative ions will react at anode. Similarly cathode has cations that are positively charged. Thus, reduction will take place at the cathode.
In the electrolysis reaction of aqueous potassium bromide -
KBr -> [tex] {K}^{+} [/tex] + [tex] {Br}^{-} [/tex]
In this ionization reaction, the KBr is potassium bromide, [tex] {K}^{+} [/tex] are potassium ions amd [tex] {Br}^{-} [/tex] are bromine ions. The negatively charged bromine ions will be oxidised at anode.
2[tex] {Br}^{-} [/tex] -> [tex] Br_{2}[/tex] +[tex] {2e}^{-} [/tex]

In hydrogen fluoride, symmetry allows for HF overlap between the H 1s and F 2s orbitals, but the energy gap between the two atomic orbitals precludes them from interacting to form a molecular orbital.
Which type of orbital has more energy?P-orbitals: At every level, the p-orbitals have more energy than the s-orbitals. One node, or region with no electrons, exists in the p-orbitals.Combining the atomic orbitals of the molecules' atoms yields molecular orbitals.The s bonding orbital and the s antibonding orbital must both have two electrons, giving a total of four valence electrons.The quantity of electron pairs that connect two atoms in a bond is known as the bond order.The highest-energy MO with electrons is known as HOMO, or Highest Occupied MO.Nonmetals, which can be found in the periodic table's right-hand section, have relatively high ionization energies and so have a propensity to gain electrons.Nearer to the F atom is the electron density.Fluorine attracts the electron density toward itself since it has a substantially greater electronegativity value than hydrogen.To learn more about molecular orbital refer to :

what volume of 5.00X10^-3 M HNO3 is needed to titrate 80.00 mL of 5.00X 10^-3 M Ca(OH)2 to the equivalence point
160 ml of HNO3 is needed to titrate against Ca(OH)2 to the equivalence point. This is calculated from the concept of molarity.
Molarity is defined as the number of moles of solute (n) divided by the volume (V) of the solution in liters. It is important to note that the molarity is defined as moles of solute per liter of solution, not moles of solute per liter of solvent.
Volume = moles / molarity
Ca(OH)₂ + 2HNO₃ → Ca(NO₃)₂ + 2H₂O
From the stoichiometry of the reaction it is clear that,
2 mole of HNO₃ = react with 1 mole of Ca(OH)₂
volume of Ca(OH)₂ = 80mL = 0.080L
molarity of Ca(OH)₂₂ = 5×10⁻³ M
Moles of Ca(OH)₂ = 0.080L x 5×10⁻³M = 0.0004 moles
0.0004 moles of Ca(OH)₂ = react with 2×0.0004 = 0.0008 moles of HNO₃
molarity of HNO₃ = 5×10⁻³ M
Volume of HNO₃ = 0.0008moles / 5×10⁻³ M = 0.16L = 160mL

Answer:

Explanation:
0.10 mol of NaCl contains 0.10 mol of Cl- and 0.10 mol of CaCl2 contains 0.20 mol of Cl-. So, to precipitate all of the Cl- as AgCl(s), the minimum number of moles of AgNO3 must be 0.20 mol plus 0.10 mol, which equals 1.20 mol.
what is the rate of effusion for a sample of a nitrogen gas, if a sample of sulfur dioxide gas diffuses through the apparatus at a rate of 0.452 mol/min
The rate of effusion of nitrogen gas is 0.98[tex]\frac{mol}{min}[/tex].
The rate of effusion of sulphur dioxide gas, which has a mass of 64g, is 0.452; the rate of effusion of nitrogen gas, which has a mass of 14g, has to be determined.
The square root of the molar mass of a gas has an inverse relationship with the rate of effusion of that gas. As a result, the rate of diffusion or effusion of a molecule or mole of molecules is precisely proportional to the rate of movement.
Now, using the relationship between mass and rate of effusion.
[tex]\frac{rate}{rate1} =\sqrt{\frac{MM1}{MM} }[/tex]
rate= 0.452
M.M.=64g
M.M.1=14g
Putting the values of all variable in formula we get,

- What causes the trend in ionization energy across a period and within a group?
The ionization energy of elements rises as we span a period from left to right. This is brought on by the periodic drop in atom size. As we proceed from left to right, the higher nuclear charge causes the valence electrons to move closer to the atom's nucleus.
What are General periodic trends of ionization energy?In a group, while moving from top to bottom it decreases.
It increases from left to right across a period
As we go lower in a group, the first ionization enthalpy of the elements drops. The number of shells and the atomic number both rise as a group moves downward. Since they are far from the nucleus, outermost electrons are easily eliminated. The shielding effect brought on by the increasing number of shells as we progress along a group is the second component that lowers the ionization energy.

NO₂: 3 moles ×46 g/mole= 138 gramsH₂O: 1 mole ×18 g/mole= 18 gramsHNO₃: 2 moles ×63 g/mole= 126 gramsNO: 1 mole ×30 g/mole= 30 gramsMass of NO formedThe following rule of three can be applied: if by reaction stoichiometry 3 moles of NO₂ form 30 grams of NO, 4.96 moles of NO₂ form how much mass of NO?
mass of NO= (4.96 moles of NO₂× 30 grams of NO)÷3 moles of NO₂
mass of NO= 49.6 grams
Finally, 49.6 grams of NO can be formed.
