The charge of these ionic acids, of course, always must be balanced by ions of opposite charges, but these oppositely charged ions usually are irrelevant to the acid base properties of the system.
None of the above; it's the constitution, stupid.James Decandole Toronto SIR – Thinking about particle accelerators ("Small really is beautiful", October 19th), I propose creating the Large Ego Collider in which our congressmen are accelerated into ever higher-energy collisions with their oppositely charged colleagues.
In this, an electrically charged syringe squirts a polymer mixed with a solvent towards an oppositely charged electrode.
The leaves are arranged oppositely on twigs.
A carbonium ion produced by heterolysis (decomposition of a compound into oppositely charged particles or ions) may lose a proton, thereby effecting a 1,2-elimination reaction: Such eliminations, which generally accompany nucleophilic substitutions, are promoted by electron release to the carbonium ion centre.
The leaves are typically simple and oppositely arranged; most are fragrant and contain volatile oils.
Parapositronium, in which the spins of the positron and electron are oppositely directed, decays by annihilation into two photons, with a mean life of about one-tenth of a nanosecond (or 10-10 second; a nanosecond is 10−9 second); and orthopositronium, in which the spins are in the same direction, annihilates into three photons with a mean life of about 100 nanoseconds (10-7 second).
In the case of waves moving in the same direction, interference produces a travelling wave; for oppositely moving waves, interference produces an oscillating wave fixed in space.
Ionic compounds contain ions and are held together by the attractive forces among the oppositely charged ions.
The M1 cation strip is bonded to oxygen atoms of two oppositely pointing tetrahedral chains.
Because the two are oppositely directed forces, the total force on the object is zero, and the speed of the object has become constant.
