How does the pressence of an acid in a water solution affect the pH of the solution?
An acid is capable of releasing (donating) protons to watermolecules, thus lowering the pH to acidic level (below 7, in water)
Why all molecules with protons are not acids?
Assuming the Brønsted-Lowry definition of acids and bases, an acid is a molecule that donates a proton. While all atoms -- and therefore all molecules -- contain protons, not all are capable of donating them. Those that cannot donate a proton are not considered an acid under this terminology.
Which is capable of independent existence an atom or molecule?
Atoms of most elements are not able to exist independently. Atoms form molecules or ions aggregate in large numbers to form the matter that we can see. Molecule is capable of independent existence.
WHYNh3 is stong bond?
NH3 is a strong bond because it is capable of hydrogen bonding. when it comes to intermolecular forces (dispersion, dipole-dipole, hydrogen bonding, and ion-dipole) hydrogen bonding is one of the strongest. Molecules containing Hydrogen atoms bonded with Flourine(ex-FH), Oxygen(ex-H2O), or Nitrogen(ex-NH3) are capable of hydrogen bonding because they are extremely polar. Even though the Nitrogen and Hydrogen atoms "share" atoms through covalent bonds, the electrons tend to hover closer to Nitrogen. This results in the Hydrogen atoms becoming partially positive in charge while the Nitrogen atom gains a partially negative charge. When a molecule of NH3 comes in contact with another molecule of NH3, the positive (Hydrogen) end of one molecule attracts the negative (Nitrogen) end of the other. This ability of the partially positive Hydrogen atoms to form strong bonds with other polar molecules (IE. Hydrogen Bonding) is why NH3 forms strong bonds.
Which of these is the best reducing agent H2 Na O2 Li Ca?
H2 (hydrogen gas) is the best reducing agent among the options provided. A good reducing agent tends to easily lose electrons to other substances, making it capable of reducing another substance by donating electrons. Hydrogen has a strong tendency to donate its electrons and is often used as a reducing agent in various chemical reactions.
What are hydrogen donating compounds?
Hydrogen donating compounds are molecules that can release hydrogen atoms in chemical reactions. These compounds often contain hydrogen atoms that are bonded to more electronegative atoms, such as oxygen or nitrogen, making them capable of donating their hydrogen atoms to other molecules or radicals. An example of a hydrogen donating compound is ascorbic acid (vitamin C).
What is capable of releasing more energy then carbohydrates?
gasoline, hydrogen, and the fission of uranium
How many bonds is a water molecule capable of forming?
A water molecule can form up to four hydrogen bonds, one with each of the two hydrogen atoms and two with the oxygen atom.
How does the pressence of an acid in a water solution affect the pH of the solution?
An acid is capable of releasing (donating) protons to watermolecules, thus lowering the pH to acidic level (below 7, in water)
Is water capable of making four Hydrogen bonding interaction?
Yes, water is capable of forming a maximum of four hydrogen bonding interactions. A water molecule can form two hydrogen bonds with neighboring molecules, one using each of its hydrogen atoms, resulting in a total of four hydrogen bonds.
Is water capable of hydrogen bonding?
Yes, water is capable of hydrogen bonding.
A hydrogen bond can form between a hydrogen atom of one molecule and which atom of another molecule?
since hydrogen atom has no electron in its shell, it acquires positive charge. when a negatively charged atom comes in contact with hydrogen atom, it donates h atom a electron to make a covalent bond. but when it breaks the negative atom restores its electron.
Why Hno3 is an acid?
HNO3 is an acid because it can release hydrogen ions (H+) in solution, making it capable of donating a proton to other substances. This proton donation is what classifies it as an acid according to the Brønsted-Lowry definition.
A chemical capable of donating hydrogen ions to other substances is?
Well, it depends on what ion you are talking about: the H+ ion, 'proton,' or the H- hydride ion. Anions, Lewis bases accept the proton or H+ ion (HCl); but active metals can react with H- to form metal hydrides (NaH for example)
How many hydrogen bonds can ammonia molecule forms?
Intramolecular forces; Hydrogen bonds occur in ammonia between the nitrogen and the hydrogen, NH3.Intermolecular forces:Hydrogen bonding between molecules occurs between the electronegative nitrogen atom (N) of one molecule of ammonia and an electropositive hydrogen atom (H) bonded to a nitrogen of different molecule of ammonia.
What is true about a base in science?
A base is one which has fulfilled orbitals and lone pairs and which is capable donating electrons to an acid
What molecules is like H20 and how is this molecule alike?
...this is a very broad question. H2S is like water in that it has two hydrogens and has similar geometry to water...but it'll kill you dead. Ethanol is kind of like water because it is capable of hydrogen bonding and is a decent solvent.
