Answer:

Explanation:

#2 is answered so here is for #3:

Knowns: 100mL of solution; concentration of 0.7M

Unknown: number of moles

Equation: number of moles = volume * concentration

Plug and Chug: number of moles = 100/1000 * 0.7 = 0.07 mole

Final Answer: 0.07mole

Sodium (Na) is an explosive metal, while Chlorine (CI) is a toxic gas. However, when bonded together they form regular table sal
RUDIKE [14]

Answer:

When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl-), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.

You have 26.7 mL of 0.061 mol/L aqueous potassium hydroxide (KOH(aq)) in a conical flask. In a burette
Natasha2012 [34]

Answer:

9.47 mL

Explanation:

The reaction that takes place is:

  • 2KOH + H₂SO₄ → K₂SO₄ + 2H₂O

First we <u>calculate how many KOH moles reacted</u>, using <em>the given concentration and volume of KOH solution</em>:

  • 0.061 mol/L = 0.061 mmol/mL
  • 0.061 mmol/mL * 26.7 mL = 1.6287 mmol KOH

Then we <u>convert KOH moles into H₂SO₄ moles</u>, using the <em>stoichiometric coefficients</em>:

  • 1.6287 mmol KOH * \frac{1mmolH_2SO_4}{2mmolKOH} = 0.8144 mmol H₂SO₄

Finally we <u>calculate the required volume of the H₂SO₄ solution</u>, using<em> the number of moles and given concentration</em>:

  • 0.8144 mmol ÷ 0.086 mmol/mL = 9.47 mL
