Answer: trigonal bipyramidal
Explanation:
Number of electron pairs = [tex]\frac{1}{2}[V+N-C+A][/tex]
V = number of valence electrons present in central atom
N = number of monovalent atoms bonded to central atom
C = charge of cation
A = charge of anion
[tex]SbCl_5[/tex] :
In the given molecule, antimony is the central atom and there are five chlorine as monovalent atoms.
The number of electron pairs are 5 that means the hybridization will be [tex]sp^3d[/tex] and geometry of the molecule will be trigonal bipyramidal.

The given question is incomplete. The complete question is:
Ammonium phosphate [tex](NH_4)_3PO_4[/tex] is an important ingredient in many solid fertilizers. It can be made by reacting aqueous phosphoric acid [tex]H_3PO_4[/tex] with liquid ammonia. Calculate the moles of ammonium phosphate produced by the reaction of 1.7 mol of ammonia. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.
Answer: 0.57 moles of ammonium phosphate are produced by the reaction of 1.7 moles of liquid ammonia
Explanation:
The balanced chemical equation is:
[tex]H_3PO_4+3NH_4OH\rightarrow (NH_4)_3PO_4+3H_2O[/tex]
According to stoichiometry:
3 moles of liquid ammonia [tex](NH_4OH)[/tex] produces = 1 mole of ammonium phosphate [tex](NH_4)_3PO_4[/tex]
Thus 1.7 moles of liquid ammonia [tex](NH_4OH)[/tex] produces = [tex]\frac{1}{3}\times 1.7=0.57[/tex] mole of ammonium phosphate [tex](NH_4)_3PO_4[/tex]
Thus 0.57 moles of ammonium phosphate are produced by the reaction of 1.7 moles of liquid ammonia

To determine the concentration of a sodium thiosulfate solution as in this experiment, a student pipetted 25.0 mL of 0.0100 M potassium iodate (KIO3) solution into a 125 mL Erlernmeyer flask. Potassium iodide and sulfuric acid were added as in this experiment. The titration needed 15.21 mL of the sodium thiosulfate to reach the end point. What is the concentration of the sodium thiosulfate solution
Answers
Answer:
0.0986M is the concentration of the Na₂S₂O₃ solution
Explanation:
Potassium iodate, KIO₃, reacts with sodium thiosulfate, Na₂S₂O₃, as follows:
KIO₃ + 6Na₂S₂O₃ +5KI + 3H₂SO₄ → 3H₂O + 3K₂SO₄ + 3Na₂S₄O₆ + 6NaI
To solve this question we must find the moles of sodium thiosulfate that reacts as follows:
Moles KIO₃:
0.0250L * (0.0100mol / L) = 2.5x10⁻⁴moles KIO₃
Moles Na₂S₂O₃:
2.5x10⁻⁴moles KIO₃ * (6mol Na₂S₂O₃ / 1mol KIO₃) = 1.5x10⁻³ moles Na₂S₂O₃
Molar concentration:
1.5x10⁻³ moles Na₂S₂O₃ / 0.01521L =

A 5.00 g piece of metal is heated to 100.0 C then placed in a beaker containing 20.0 g of water at 10.0 C. The temperature of the water rises to 15.0 C. Calculate the specific heat of the metal
Answers
q = mCpΔT
m = 20.0 g
Cp = 4.186 J/g°C
ΔT = T(final) - T(initial) = 15.0°C - 10.0°C = 5.0°C
q = (20.0)(4.186)(5.0) = 419 J
This is equal to the heat lost by the metal, so calculate Cp for the metal, given:
q = -419 J (negative because heat was lost)
m = 5.00 g
ΔT = 15.0°C - 100.0°C = -85.0°C (negative because the temperature decreased)
q = mCpΔT —> Solve for Cp —> Cp = q/mΔT
Cp = -419 / (5.00 • -85.0) = 0.986 J/g°C

(5. infrared spectral analysis determines that the unknown hydrocarbon does NOT contain oxygen. How many moles of O2 are used in combusting the unknown sample?)
Answers
1: 10 mol CO2
2: C10H24
3: 12 mol H2O
4: 0.5 mol
5: 16 mol O2
The compound is C5H10.
From the information available in the question;
Number of moles of carbon dioxide = 440.00 g/44 g/mol = 10 moles
Number of moles of water vapor = 216.00 g/18 g/mol = 12 moles
Mass of carbon = 10 moles × 12 g/mol = 120 g of carbon
Moles of hydrogen = 12 moles × 2 g/mol = 24 g of hydrogen
Number of moles of carbon = 120 g/12 g/mol = 10 moles
Number of moles of hydrogen = 24 g/1 g/mol =24 moles
Divide through by the lowest number of moles =
C - 10/10 H - 24/10
C - 1 H - 2
The empirical formula is CH2
Molar mass of the compound = 72 g/mol
[12 + 2(1)]n = 72
14n = 72
n = 5
The compound is C5H10.

A balloon filled with helium has a volume of 30.0 L at a pressure of 100 kPa and a temperature of 15.0°C. What will the volume of the balloon be if the temperature is decreased to -80.0°C and the pressure remains constant?
Answers
Answer:
[tex]V_2=20.1L[/tex]
Explanation:
Hello there!
In this case, since this is a problem in which the pressure of the gas remains constant, we can use the Charles' law as a directly proportional relationship between temperature (in Kelvins) and volume given by:
[tex]\frac{V_2}{T_2} =\frac{V_1}{T_1}[/tex]
Thus, solving for the final volume as the temperature is decreased to -80.00 °C, we obtain:
[tex]V_2=\frac{V_1T_2}{T_1}[/tex]
[tex]V_2=\frac{30.0L*(-80+273)K}{(15+273)K} \\\\V_2=20.1L[/tex]
