Answer:
Maintenance of homeostasis usually involves negative feedback loops. These loops act to oppose the stimulus, or cue, that triggers them.
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 *
= 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
The mass of GeCl4 that would be formed will be 1.51 g
<h3>Stoichiometric calculations</h3>
From the balanced equation of the reaction:
Ge (s) + 2Cl2 (g) →GeCl4
The mole ratio of Ge and Cl2 is 1:2.
Mole of 1.0 g Ge: 1/72.64
= 0.01377 mole
Mole of 1.0 g Cl2 = 1/71
= 0.01408 mole
Thus, Cl2 is limiting.
Mole ratio of Cl2 and GeCl4 = 2:1
Equivalent mole of GeCl4 = 0.01408/2
= 0.0070 mole
Mass of 0.0070 mole GeCl4 = 0.0070 x 214.4
= 1.51 g
