Why water generally has a neutral pH even though water molecules dissociate?
The number of cations and anions is identical.
What kind of bond do hydrogen and clorine make?
Hydrogen and chlorine form a covalent bond when they combine to make hydrogen chloride (HCl). In this type of bond, electrons are shared between the two atoms to achieve a stable electron configuration.
Is matter usually charge-neutral?
Yes, matter is typically charge-neutral because it contains equal numbers of positively and negatively charged particles (protons and electrons, respectively). This balance of charges allows matter to maintain a neutral overall charge.
What is an acid that does not dissociate 100 percent of its ions?
Theoritically, there exists no acid that can fully dissociate into ions in aqueous medium. Though, for practical purposes, it is often assumed that strong acids such as nitric acid, hydrochloric acid etc. are fully dissociated. Other than these few strong acids, all other acids partially dissociate, a common example is acetic acid.
What is the difference between mineral acids and strong acids?
The main difference is that a mineral acid (for instance, sulfuric acid) will dissociate completely in solution, while an organic acid (for instance, acetic acid) will dissociate only partially. Specifically: When you put sulfuric acid (H2SO4) into water, all of the molecules of acid will dissociate into two protons (H+) and sulfate anions (SO4=). There will be no intact molecules of H2SO4 in solution. When you put acetic acid (CH3COOH) into water, only some of the molecules dissociate into proton (H+) and acetate anions (CH3COO-). Some of the acetic acid molecules remain intact in solution.
Why water generally has a neutral pH even though water molecules dissociate?
The number of cations and anions is identical.
Is a element a molecules?
Molecules are not elements. Elements make up molecules, though.
Why can gamma rays ionise atoms even though they have no mass?
This phenomenon is known as Photo electri emission. Though radiations such as Gamma, X ray, ultraviolet and even visible light are not having massive particles, they are able to eject electrons right from the neutral atoms or molecules.
Why is it that a charged object can attract a second object even if that object is neutral?
An object can have a net charge of zero, but also have sections that are charged, as long as those charges algebraically add up to zero, for example, a charge of +1 is balanced by a charge of -1 in a different location. So a charged object can be attracted to a particular part of a neutral object. This is a common phenomenon in molecular chemistry. Water molecules attract other water molecules in this manner, because they have positive and negative poles, even though the water molecule itself is neutral.
When an atom loses electrons though an ionic bond it becomes what?
neutral
Molecules move into and out of a cell though the?
Cell Membrane
Are molecules r always in motion?
Welll . . . molecules are always in motion except when their temperature is 0 degrees, Kelvin. There are not a lot of molecules that cold, though.
What kind of bond do hydrogen and clorine make?
Hydrogen and chlorine form a covalent bond when they combine to make hydrogen chloride (HCl). In this type of bond, electrons are shared between the two atoms to achieve a stable electron configuration.
Are intersecting lines perpendiculer?
Generally not, though they can be.
Does meteors have water?
Generally no. Comets do though.
Are phospholipids charged at pH 7?
Phospholipids are typically uncharged molecules at pH 7 as they have a neutral overall charge. The phosphate group in phospholipids is usually ionized and carries a negative charge, but the overall charge of the molecule is balanced by the other components, making it neutral.
Is matter usually charge-neutral?
Yes, matter is typically charge-neutral because it contains equal numbers of positively and negatively charged particles (protons and electrons, respectively). This balance of charges allows matter to maintain a neutral overall charge.
