The answer is each indicator has a narrow range.  We need many different indicators to span the entire ph spectrum because each indicator has a narrow range.

vTo be fair, you have to have a very high IQ to understand Rick and Morty. The humour is extremely subtle, and without a solid grasp of theoretical physics most of the jokes will go over a typical viewer's head. There's also Rick's nihilistic outlook, which is deftly woven into his characterisation- his personal philosophy draws heavily from Narodnaya Volya literature, for instance. The fans understand this stuff; they have the intellectual capacity to truly appreciate the depths of these jokes, to realise that they're not just funny- they say something deep about LIFE. As a consequence people who dislike Rick & Morty truly ARE idiots- of course they wouldn't appreciate, for instance, the humour in Rick's existential catchphrase "Wubba Lubba Dub Dub," which itself is a cryptic reference to Turgenev's Russian epic Fathers and Sons. I'm smirking right now just imagining one of those addlepated simpletons scratching their heads in confusion as Dan Harmon's genius wit unfolds itself on their television screens. What fools.. how I pity them.

And yes, by the way, i DO have a Rick & Morty tattoo. And no, you cannot see it. It's for the ladies' eyes only- and even then they have to demonstrate that they're within 5 IQ points of my own (preferably lower) beforehand. Nothin personnel kid

Potassium sulfate has a solubility of 15g/100g water at 40 Celsius. A solution is prepared by adding 39.0g of potassium sulfate
nadya68 [22]

Answer:

5.25 grams of potassium sulfate will get crystallize out.

Explanation:

Solubility of potassium sulfate at 40 °C = 15 g/100 g

This means that at 40 °C 15 g of potassium sulfate will get completely dissolved in 100 of water.

39.0 g of potassium sulfate to 225 g water, carefully heating the solution.

Amount of potassium sulphate will get dissolve in 225 g of water at 40 °C will be:

\frac{15g}{100g} × 225 = 33.75g

Amount of potassium sulfate precipitated out by the solution:

= 39.0 g-33.75 g = 5.25 g

At 40 °C 5.25 g of potassium sulfate will get precipitate out from the solution which means that solution is saturated.

Saturated solution are solution in which solute is dissolved in maximum amount. Further addition of solute results in precipitation of solute form the solution.

5.25 grams of potassium sulfate will get crystallize out.

Can someone solve Thierry two problems
olga2289 [7]

Answer:

5.00 × 10⁻⁴ mol HCl; 100 mL NaOH

Step-by-step explanation:

3. Moles of HCl

<em>Data: </em>

V(HCl) = 500 mL

    pH = 3

<em>Calculations: </em>

            pH = 3

      [H₃O⁺] = 10⁻³ mol·L⁻¹

              V = 500 mL × (1 L/1000 mL) = 0.500 L

Moles HCl = volume × concentration

                 = 0.500 L × (10⁻³ mol/1 L)

                 = 5.00 × 10⁻⁴ mol

4. Volume of NaOH

NaOH + HCl ⟶ NaCl + H₂O

<em>Data: </em>

[NaOH] = 0.01 mol·L⁻¹

   [HCl] = 0.02 mol·L⁻¹

V(HCl) = 50 mL

<em>Calculations: </em>

    Moles HCl = 0.050 L × (0.02 mol/1 L)

                      = 1.0 × 10⁻³ mol

Moles NaOH = 1.0 × 10⁻³ mol HCl × (1 mol NaOH/1 mol HCl)

                      = 1.0 × 10⁻³ mol NaOH

      V(NaOH) = 1.0 × 10⁻³ mol NaOH × (1 L NaOH/0.01 mol NaOH)

                      = 0.1 L NaOH     Convert to millilitres

                      = 100 mL NaOH
