If a solution is strongly acidic, what anionscannot be present in appreciableconcentrations?

Chemistry
1 answer:
masha68 [24]3 years ago
7 0

Explanation:

OH^- cannot be present in appreciable concentrations in a solution that is strongly acidic in nature. A weak acid is a complex that consists of hydrogen bound to an anion that does not dissociate well in solution comparing to a strong acid which dissolves completely to an anion. Therefore, OH^- cannot be present in appreciable concentrations in a solution that is strongly acidic in nature.

List the following elements from increasing electronegativity: boron, magnesium, calcium, chlorine, argon
pishuonlain [190]

Answer:

The list of elements from increasing electronegativity: Calcium <  magnesium < chlorine < argon < boron.

Explanation:

In the periodic table if you move from left to right there would be an increase in the electronegativity of the elements. If you move from the bottom to the top of the groups in the periodic table the electronegativity increases and if u move to the bottom from down its decreases.

Calcium is in the 2nd group below magnesium so calcium is the least electronegative among given elements then magnesium and then chlorine as it is top of magnesium then argon, as it is right to the chlorine, and boron has the most electronegativity as it is above rest of the elements.

The current scientific verdict on the phlogiston theory demonstrates which two of the following principles?
masha68 [24]

Answer:

The two valid principles are:

  • Scientific theories can be replaced by better theories.
  • An experiment can disprove a theory that scientists have accepted.

Explanation:

The scientific knwoledge is not inmutable; it may (and does) change with new discoveries.

In fact, scientific theories cannot be proved right, instead they are constantly tested to try to  disprove them. This is what the principle that theories are falsiable means.

As long as a scientific theory is not disproved it remains valid, but new discoveries may lead, eventually, to its disprovement.

Scientific knowledge evolves because new procedures, new technologies, and new evidence leads to a better understanding and better explanations.
