Stomach acid is approximately 0.10 M HCl. How many mL of stomach acid can be neutralized by one regular antacid tablet that cont
Radda [10]

Answer:

100 mL

Explanation:

The reaction that takes place is:

  • CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂

First we <u>convert 500 mg of CaCO₃ into mmoles</u>, using its <em>molar mass</em>:

  • 500 mg ÷ 100 mg/mmol = 5 mmol CaCO₃

Then we <u>convert 5 mmoles of CaCO₃ into HCl mmoles</u>, using the <em>stoichiometric coefficients of the balanced reaction</em>:

  • 5 mmol CaCO₃ * \frac{2mmolHCl}{1mmolCaCO_3} = 10 mmol HCl

Finally we <u>calculate the volume of a 0.10 M HCl solution (such as stomach acid) that would contain 10 mmoles</u>:

  • 10 mmol / 0.10 M = 100 mL

The wavelength propagates to 15 m with a frequency of 0.3 HZ<br><br> What is the speed of this wave?
ololo11 [35]

Answer:

c=50\frac{m}{s}

Explanation:

Hello!

In this case, given the relationship between velocity, wavelength and frequency:

c=\lambda *f

By plugging in the given wavelength and frequency, we obtain the following speed:

c=15m*0.3\frac{1}{s}\\\\c=50\frac{m}{s}

Best regards!
