The mass of silver chloride, AgCl, that can be produced from the reaction is 2.76 g
We'll begin by calculating the number of mole of silver nitrate, AgNO₃ and calcium chloride, CaCl₂ in the solution.
For AgNO₃:Volume = 120.0 mL = 120 / 1000 = 0.12 L
Molarity = 0.16 M
Mole of AgNO₃ =?Mole = Molarity x Volume
Mole of AgNO₃ = 0.16 × 0.12
Mole of AgNO₃ = 0.0192 moleFor CaCl₂:Volume = 120.0 mL = 120 / 1000 = 0.12 L
Molarity = 0.22 M
Mole of CaCl₂ =?Mole = Molarity x Volume
Mole of CaCl₂ = 0.22 × 0.12
Mole of CaCl₂ = 0.0264 mole Next, we shall determine the limiting reactant2AgNO₃ + CaCl₂ —> 2AlCl + Ca(NO₃)₂
From the balanced equation above,
2 moles of AgNO₃ reacted with 1 mole of CaCl₂.
Therefore,
0.0192 mole of AgNO₃ will react with = 0.0192 / 2 = 0.0096 mole of CaCl₂
From the calculation made above, we can see that only 0.0096 mole of CaCl₂ out of 0.0264 mole given, is needed to react completely with 0.0192 mole of AgNO₃.
Therefore, AgNO₃ is the limiting reactant and CaCl₂ is the excess reactant.
Next, we shall determine the number of mole of AgCl produced from the reaction using the limiting reactant.2AgNO₃ + CaCl₂ —> 2AlCl + Ca(NO₃)₂
From the balanced equation above,
2 moles of AgNO₃ reacted to produce 2 moles of AlCl.
Therefore,
0.0192 mole of AgNO₃ will also react to produce = 0.0192 mole of AgCl
Finally, we shall determine the mass of AgCl produced from the reactionMole of AgCl = 0.0192 mole
Molar mass of AgCl = 108 + 35.5 = 143.5 g/mol
Mass of AgCl =?Mass = mole × molar mass
Mass of AgCl = 0.0192 × 143.5
Mass of AgCl = 2.76 gThus, the mass of AgCl produced from the reaction is 2.76 g

The molar mass of the diprotic acid, H₂X is 84.9 g/mol
We'll begin by calculating the number of mole in 13.96 mL of 0.1051 M NaOH. This can be obtained as follow:
Volume = 13.96 mL = 13.96 / 1000 = 0.01396 L
Molarity of NaOH = 0.1051 M
Mole of NaOH =?
Mole = Molarity x Volume
Mole of NaOH = 0.1051 × 0.01396
Mole of NaOH = 0.00147 mole Next, we shall determine the number of mole of the diprotic acid, H₂X required to react with 0.00147 mole of NaOH. This can be obtained as follow:H₂X + 2NaOH —> Na₂X + 2H₂O
From the balanced equation above,
2 moles of NaOH reacted with 1 mole of H₂X.
Therefore,
0.00147 mole of NaOH will react with = 0.00147 / 2 = 0.000735 mole of H₂X.
Finally, we shall determine the molar mass of H₂X.Mole of H₂X = 0.000735 mole
Mass of H₂X = 0.0624 g
Molar mass of H₂X =?Molar mass = mass / mole
Molar mass of H₂X = 0.0624 / 0.000735

empitical
take 100 gm of the compound
f O Divide by atomi wt of O to get moles
51.54/ 16.0 = 3.22
now if there is 1 atom of C and one of O, there will be 3 of H, so
CH3O is the empirical formula
the molar mass of the compound is 62-63. the mass of CH3O is
12 + 16 +3 = 31
2 X31 =62

A student weighs out a sample of 9.4 mg of an unknown metal. The sample of metal reacts with hydrochloric acid at a pressure of 1 atm and 25.0˚C to form 9.51 mL of hydrogen gas. Assuming the unknown metal has a +2 oxidation state, what is the identity of the metal?
The identity of the metal is Magnesium, Mg
Let the unknown metal be M
Next, we shall determine the number of mole of H₂ produced from the reaction.Pressure (P) = 1 atm
Temperature (T) = 25 °C = 25 + 273 = 298 K
Volume (V) = 9.51 mL = 9.51 / 1000 = 0.00951 L
Gas constant (R) = 0.0821 atm.L /Kmol
Number of mole (n) =?PV = nRT
1 × 0.00951 = n × 0.0821 × 298
0.00951 = n × 24.4658
Divide both side by 24.4658
n = 0.00951 / 24.4658
n = 3.89×10¯⁴ mole Next, we shall determine the mole of the metal needed to produce 3.89×10¯⁴ mole of H₂.M + 2HCl —> MCl₂ + H₂
From the balanced equation above,
1 mole of M reacted to produce 1 mole of H₂.
Therefore,
3.89×10¯⁴ mole of M will also react to 3.89×10¯⁴ mole of H₂.
Finally, we shall determine the identity of the metal, M.Mass of metal = 9.4 mg = 9.4×10¯³ g
Mole of metal = 3.89×10¯⁴
Molar mass of metal =?Molar mass = mass / mole
Molar mass of metal = 9.4×10¯³ / 3.89×10¯⁴

What is the concentration of potassium ions in a solution obtained by mixing 480. mL of 0.410 M potassium hydroxide(aq) with 440. mL of 0.290 M potassium sulfate(aq). Enter your answer in decimal notation rounded to the appropriate number of significant figures.
The concentration of potassium ions, K⁺ in the solution obtained by mixing 480 mL of 0.410 M KOH with 440 mL of 0.290 M K₂SO₄ is 0.491 M
We'll begin by calculating the number of mole of potassium ion, K⁺ in each solution.
For KOH:Volume = 480 mL = 480 / 1000 = 0.48 L
Molarity = 0.410 M
Mole of KOH =?Mole = Molarity x Volume
Mole of KOH = 0.410 × 0.48
Mole of KOH = 0.1968 moleKOH(aq) —> K⁺(aq) + OH¯(aq)
From the balanced equation above,
1 mole of KOH contains 1 mole of K⁺
Therefore,
0.1968 mole of KOH will also contain 0.1968 mole of K⁺
Thus, 0.1968 mole of K⁺ is present in 480 mL of 0.410 M KOH
For K₂SO₄:Volume = 440 mL = 440 / 1000 = 0.44 L
Molarity = 0.290 M
Mole of K₂SO₄ =?Mole = Molarity x Volume
Mole of K₂SO₄ = 0.290 × 0.44
Mole of K₂SO₄ = 0.1276 moleK₂SO₄(aq) —> 2K⁺(aq) + SO₄²¯(aq)
From the balanced equation above,
1 mole of K₂SO₄ contains 2 moles of K⁺
Therefore,
0.1276 mole of K₂SO₄ will contain = 0.1276 × 2 = 0.2552 mole of K⁺
Thus, 0.2552 mole of K⁺ is present in 440 mL of 0.290 M K₂SO₄
Next, we shall determine the total mole of K⁺ in the resulting solution.Mole of K⁺ in KOH = 0.1968 mole
Mole of K⁺ in K₂SO₄ = 0.2552 mole
Total mole = 0.1968 + 0.2552
Total mole = 0.452 moleNext, we shall determine the total volume of the resulting solutionVolume of KOH = 0.48 L
Volume of K₂SO₄ = 0.44 L
Total volume = 0.48 + 0.44
Total volume = 0.92 LFinally, we shall determine the molarity of K⁺ in the resulting solutionTotal mole = 0.452 mole
Total volume = 0.92 L
Molarity of K⁺ =?Molarity = mole / Volume
Molarity of K⁺ = 0.452 / 0.92
Molarity of K⁺ = 0.491 MTherefore, the molarity of potassium ion, K⁺ in the resulting solution is 0.491 M

H2(g) + I2(g) → 2HI(g)
A student makes the following statements:
Hydrogen always has the same oxidation number, so it has an oxidation number of +1 in both the reactant H2 and product HI.
Iodine is in Group VIIA, so it has an oxidation number of –1 in both the reactant I2 and product HI.
Neither hydrogen nor iodine changes oxidation states, so the reaction is not a redox reaction.
In three to five sentences, describe the mistake that the student made, and determine whether or not the reaction is a redox reaction. Explain your answer.
The oxidation number of hydrogen increases to +1 while the oxidation number of iodine decreases to -1.
We must recall that the oxidation number of a particular atom or ion in any chemical specie is decided based on some arbitrary rules. Those rules are used to tell what the correct oxidation number of an atom should be in a compound or ion.
Firstly, the oxidation number of iodine and oxygen in the gas molecules is zero. The oxidation number of substances is not constant. However, on the right hand side, the oxidation number of hydrogen increases to +1 while the oxidation number of iodine decreases to -1.
