the hybridization of the sulfur atom change in the series SF2, SF4, SF6-Option 1 - sp, sp^3, sp^3 d^2 O sp^3, sp^3 d^2
The hybridization of the sulfur atom changes in the series SF2, SF4, SF6 as follows:
In SF2, the sulfur atom is in the sp hybridized state, meaning it has one s and one p orbital in its valence shell. This allows the sulfur to form a double bond with one fluorine atom.In SF4, the sulfur atom is sp3 hybridized, which means it has one s and three p orbitals in its valence shell. This allows the sulfur to form four single bonds with four fluorine atoms.In SF6, the sulfur atom is sp3d2 hybridized, which means it has one s, three p, and two d orbitals in its valence shell. This allows the sulfur to form six single bonds with six fluorine atoms.It is worth noting that the hybridization of the sulfur atom in SF6 is not very common and it is more likely the octahedral electron pair geometry of SF6 is achieved by the d orbitals of sulfur being empty and the sulfur atom being sp3 hybridized. In summary, the hybridization of sulfur in SF2 is sp, in SF4 is sp3, and in SF6 is sp3d2.

If 1 gram (g) of glycogen is split into maltose (no maltotriose or dextrins are produced),
what is the total mass of the product?
If 1 gram (g) of glycogen is split into maltose: The total mass of the product would be 2 grams (g).
Mass of Maltose Resulting from the Breakdown of 1 Gram of GlycogenWhen 1 gram of glycogen is broken down into maltose, the result is two molecules of maltose, each having a molecular weight of 342.29 g/mol. Therefore, the total mass of the product is equal to 2 x 342.29 g/mol, or 684.58 g/mol, which is equal to 2 grams (g).
This is because each molecule of maltose is composed of two molecules of glucose, which have a mass of 342.29 g/mol each. Therefore, when the 1 gram of glycogen is split into maltose, the total mass of the product is 2 grams (g).

what will the boiling point of CHCL3 be when the atmospheric pressure exerted on its surface is 101.325
The boiling point of CHCl₃ at a pressure of 101.325 kPa is 61.8°C (143.24°F).
What is boiling point?The boiling point is the temperature at which the pressure exerted on a liquid by the environment equals the pressure exerted by the vapor of the liquid. Under these conditions, the application of heat converts the liquid to vapor without raising the temperature.
At any temperature, the liquid partially vaporizes into the space above until the pressure exerted by the vapor reaches a characteristic value called the vapor pressure of the liquid at that temperature. As the temperature rises, the vapor pressure increases. At boiling point, vapor bubbles form in the liquid and rise to the surface.
The boiling point of a liquid changes along the pressure. The normal boiling point is the temperature at which the vapor pressure equals normal atmospheric pressure at sea level (760 mm [29.92 inches] of mercury). At sea level, water boils at 100°C (212°F).

Sulfuryl chloride is in equilibrium with sulfur dioxide and chlorine gas: so2cl2(g) so2(g) + cl2(g) a system with a volume of 1. 00 l is in equilibrium at a certain temperature with p(so2cl2) = 1. 00 bar and p(so2) = p(cl2) = 0. 10 bar. By how much will the number of moles of so2cl2 at equilibrium change if the volume is reduced to 0. 50 l? (a) increase 1-10% (b) increase 11-50% (c) decrease 1-10% (d) decrease 11-50%
The volume is decreased to 0. 50L, the number of moles of SO₂Cl₂at equilibrium will increase by 1–10% option - a is correct.
What is Le Chatelier's Principle.The guiding idea of Le Chatelier is as follows: A shift in the position of the equilibrium results from a change in one of the variables that characterize a system in equilibrium and cancels out the effects of that change.
Now to solve this question first we have to know the Le-chatelier's
Principle
The Principal that if a system in chemical equilibrium is subjected to a disturbance it tends to change in a way that opposes this disturbance.
SO₂Cl₂(g) ⇄ SO₂(g) + Cl₂(g)
Initially, there is one molecule at the left hand side of the reaction and two molecules are on the right. But, the Partial pressure of molecules on RHS is lower than LHS. Concentration of RHS molecules is Lower, forward reaction is more favorable.
Decreasing volume would result in increasing the total pressure.
Now, according to Le chatelier's Principle, the equilibrium will shift in such a way to oppose change under compression. Since there are more moles of Products than reactants, to counteract the increased pressure. The equilibrium will shift to LHS increasing the moles
of SO₂Cl₂ but since the concentration (Partial Pressure)
of SO₂Cl₂, it will not increase more than 10%
Hence, answer will be (a) Increase 1-10%.

Another definition states that concentration is the ratio of a solution's solute to its entire solution or solvent. Mass per unit volume is a common way to express concentration. However, moles or units of volume can also be used to express the solute concentration. Concentration could be per unit mass instead of volume. Concentration can be computed for any mixture, despite often being used with chemical solutions.

What is the limiting reactant? What is the excess reactant?
How much excess reactant remains when the reaction is over?
Answer:
O₂ is the limiting reactant
0.406 moles of ammonia remains after the reaction goes complete.
Explanation:
Balanced reaction is:
4NH₃ + 5O₂ → 4NO + 6H₂O
Let's determine the moles of each reactant:
12 g . 1mol / 17g = 0.706 moles of ammonia.
12 g . 1mol / 32g = 0.375 moles of oxygen.
4 moles of ammonia react to 5 moles of oxygen
Then, 0.706 moles of ammonia may react to (0.706 . 5) /4 = 0.882 moles
We only have 0.375 moles of oxygen and there are needed 0.882. O₂ is the limiting reactant. Definetely ammonia is in excess.
5 moles of oxygen react to 4 moles of ammonia
Our 0.375 moles may react to (0.375 . 4) / 5 = 0.3 moles
We have 0.706 moles of NH₃ and we only need 0.3
After the reaction goes complete (0.706 - 0.3) = 0.406 moles of ammonia still remains.

What volume of 0.75 M H₂SO4 is required to neutralize 25.0
mL of 0.427 M KOH?
A volume of 0.02845 L is required to neutralize this acid-base reaction.
To neutralize an acid with a base, you need to react with equal molar amounts of the two. The balanced chemical equation for the neutralization of sulfuric acid (H₂SO₄) with potassium hydroxide (KOH) is as follows:
H₂SO₄ + 2 KOH → K₂SO₄ + 2 H₂O
The molarity of a solution is a measure of the number of moles of solute per liter of solvent. To find out how many moles of H₂SO₄ you need to neutralize 25.0 mL of 0.427 M KOH, you first need to convert the volume of KOH to liters, using the conversion factor 1 L/1000 mL.
25.0 mL KOH × (1 L/1000 mL) = 0.025 L KOH
Then, use the molarity of the KOH solution to find out how many moles of KOH you have:
0.427 M KOH × 0.025 L KOH = 0.010675 moles KOH
Since the balanced chemical equation shows that 1 mole of H₂SO₄ reacts with 2 moles of KOH, you need twice the number of moles of KOH, or 0.010675 moles × 2 = 0.02135 moles H₂SO₄.
Finally, use the molarity of the H₂SO₄ solution to find out how much volume you need:
(0.02135 moles H₂SO₄) ÷ (0.75 M H₂SO₄) = 0.02845 L H₂SO₄
So you need a volume of 0.02845 L of 0.75 M H₂SO₄ to neutralize 25.0 mL of 0.427 M KOH. This is equivalent to 28.45 mL of 0.75 M H₂SO₄.
