Answer:
It can occur with any of the atoms mentioned
Explanation:
Hydrogen bonds are the most intense type of intermolecular force that occurs between permanent dipoles of molecules, where the positive pole is always hydrogen, and the negative pole can be fluorine(F), oxygen(O) or nitrogen(N), since these elements are quite electronegative.
In other words, these atoms most strongly attract double-bonded electrons and are negatively charged.
An example to consider is hydrogen fluoride (HF) molecules, a polar molecule. In the solid state, its molecules attract, so that the positive (hydrogen) pole of one molecule attracts the negative (fluorine) pole of another.
b. a lipid.
c. a molecule.
d. an element.
The right answer is D. all of the above.
The restoration and rehabilitation of wetlands are today major challenges to maintain a fabric of natural spaces with high heritage value. The ecological engineering that has developed over many years, inspired by methods of renaturation of coastal, alluvial, grassland and forest natural areas has specificities that it is necessary to share to allow access to the greatest number. This knowledge is built on the basis of feedback and scientific knowledge, which is itself constantly evolving. They constitute a base for conducting sustainable operations that are consistent with the maintenance of ecological trajectories as close as possible to the natural model in balance with human activities.
Answer:
The mass is 104 grams.
Explanation:
What did Bohr’s model of the atom include that Rutherford’s model did not have?
The answer is energy levels
The strong acid and strong base has high rate constant of dissociation. Weak acid and base are the one whose rate constant for the dissociation is low, they do not dissociate readily in water. Therefore, the given statement is false.
Acid is a solution which releases H⁺ hydrogen ion when dissolved in water. Base are the solution which releases hydroxide ion OH⁻ ion when dissolved in water. pH is measurement of hydronium ion.
A buffer is a solution containing either a weak acid and its salt or a weak base and its salt, which is resistant to changes in pH. The statement is false. When you add an acid or base in amounts greater than the buffer capacity you no longer have the buffer to influence solution pH.
Therefore, the given statement is false.
