<span>Explain the difference between a weak acid and a strong acid according to the Arrhenius theory his question in english</span>
Answer:
[CH₃COOH] = 17.4 M
Explanation:
Acetic acid → CH₃COOH
Molar mass → 60 g/mol
99.5% is percent by mass concentration. It means that 99.5 grams of solute are contained in 100g of solution.
Density → 1.05 g/mL. This data is always referred to solution, not solute!.
We determine solution's volume:
1.05 g/mL = 100 g / V → V = 100 g /1.05 g/mL → 95.2 mL
Now we know, that 99.5 g of acetic acid are contained in 95.2 mL
Let's convert to mmoles → 99.5 g / 60 g/mol = 1.66 moles
We convert solution's volume to L → 95.2 mL . 1L / 1000 mL = 0.0952 L
M (mol/L) = 1.66 mol / 0.0952 L = 17.4 M
Answer: A loss of the ion concentration gradient that drives this process.
Explanation:Ouabain known as g-strophanthin, is a cardiac glycoside that can be medically used to treat hypotension.It acts by nhibiting the sodium - potassium (Na/K-ATPase) by causing a loss of the ion concentration gradient that drives it's process. Originally, it was a toxic plant that was used as an arrow poison in eastern Africa for hunting and warfare. Recently, Ouabain is synthesized by animals and secreted from the adrenal cortex to regulate body osmosis.
