Why do you think the human stomach pH range is 2.0 - 3.0?

Biology
1 answer:
Inga [223]3 years ago
7 0

Answer:

The stomach has a pH between 1.5 and 3.5 generally and this is due to the cells in the stomach releasing hydrochloric acid.

Explanation:

So as cells in the intestines gradually release more and more sodium bicarbonate, the pH raises from around 1 to around 7. Answer 2: The stomach usually has a pH of 2 or 3

During a melting point determination, it is normal to first take a rapid rough measurement followed by a slower more accurate me
mart [117]

The right answer is A rapid temperature increase will give a melting point range that is too high.

The melting point is determined in a capillary tube. it means the temperature at which the substance is completely melted, indicated by the disappearance of the solid, will not differ by ± 4 ° C from the given value, unless otherwise indicated.

The following technique can be applied to determine the melting point:

Grind some amount of substance in a small mortar. Place in a vacuum desiccator containing silica gel or phosphorus pentoxide and allow to dry for 24 hours at room temperature (unless another method of drying is indicated in the test protocol) . Introduce the substance into a dry capillary tube 1 mm inside diameter to form a column about 3 mm high. Heat the melting device to a temperature 5 to 10 ° C below the expected melting temperature and adjust the heating so that the temperature of the enclosure rises by approximately 1 ° C per minute. Introduce the capillary tube containing the substance into the heated chamber and note the temperature at which the agglomerated substance becomes completely transparent; this temperature constitutes the melting point.

ANSWER AND EXPLAIN PLZ:)
Rudik [331]

Answer:

The independent variable in the experiment is A. the jar covers.

Explanation:

The independent variable in an experiment represents the thing that the person conducting the experiment changes or alters.  One group in the experiment had covers (this represents the experimental group) and the other group had no cover (this represents the control group which was not exposed  to the independent variable).  Since the only thing that Redi changed between the two groups was whether or not the jars were covered, this represents the independent variable.

The number of jars and the contents of the jars were constant in both experiments, and the number of maggots on the meat is the dependent variable (the result of changing the independent variable).

Hope this helps!
