Explanation:
Answer:
The perceived mass of CO2 would not be affected in large quantities because the splash constitutes small particles of water with sodium bicarbonate that is still reacting. The final calculated mass of sodium bicarbonate in the tablet would be artificially low.
Explanation:
Effervescence is a chemical process that involves the reaction of an acid with a carbonate or sodium bicarbonate, releasing carbon dioxide through a liquid. An example is seen in carbonated beverages, in these the gas that escapes from the liquid is carbon dioxide. The bubbles that are seen are produced by the effervescence of the dissolved gas, which by itself is not visible in its dissolved form.
Consider the Chemical Reaction first:
Reaction: H₂SO₄ + 2 NaCl → 2 HCl + Na₂SO₄
Now, Given mass of NaCl = 30 g
Molar mass of Nacl = 58 g/mol
Now, Number of moles of NaCl = 30/58 = 0.517 mol
Balance the equation, For every 2 molecules of NaCl, 2 molecules of HCl formed, so the number of moles would be same.
Hence, Number of moles of HCl = 0.517 mol
Now, Mass of HCl = Molar mass of HCl * Number of moles
Mass = 36 * 0.517 [ Molar mass of HCl = 36 ]
Mass = 18.62 g
In short, Your Answer would be: 18.62 Grams
Hope this helps!
