I NEED HELP!!!
True [87]

Answer:

Explanation:

Formula

Heat = m * c * delta t

t = temperature in centigrade.

The first thing you have to do is convert kelvin degrees to centigrade. The conversion factor is - 273. The formula is degrees centigrade = degrees kelvin - 273. It is easier to understand with a couple of examples.

  • 290o K = 290 - 273 = 17
  • 325. K =   325 - 273 = 52

Solution

Heat = 100.0 grams * 4.18 J/g*C * (52 - 17)

Heat = 100 * 4.18 * 35

Heat = 14630 Joules

But you want kj

Heat = 14630 / 100 = 14.63

Answer

Heat = 14.6 kj

Why did you have to remove co2 from your partially neutralized stomach acid before the titration?
shutvik [7]

Answer is: carbon dioxide (CO₂) can affect the end point of the titration.

Carbon dioxide, or carbon(IV) oxide, reacts with water and form carbonic acid, which can affect the end point of the titration, because more base is needed for neutralization of partially neutralized stomach acid.

Balanced chemical reaction of carbon dioxide and water: CO₂ + H₂O → H₂CO₃.
