Zvichienderana nendima inotevera pamusoro pemvura, chii chinoita kuti mvura ibatane.
Context:Upenyu hwakabva mugungwa rokutanga rePasi, rakaumbwa makore anenge mabhiriyoni 3,8 akapfuura. Kubvira ipapo, mvura inoramba iri morekuru rakawanda zvikuru muzvipenyu zvose. Mvura inokosha kuupenyu nemhaka yokuti inoshanda somusanganisi, inokwanisa kunyungudutsa zvinhu zvakanyungudutswa zvakadai sesodium uye chloride ions kana kuti mamwe mamolekyu maduku kuti aumbe mvura. Kana zvangonyungudutswa mumvura, zvinonyungudutswa izvi zvinowanzosangana uye naizvozvo zvinobatanidzwa mukushanda kwemakemikari kunotsigira upenyu. Mukutaura kwechimiro chayo chemorekuru, mvura ioremolekyumu duku ine chimiro chakakombama chakaumbwa nechisungo che polar covalent chematomu maviri ehydrogen (H) kune imwe atomu yeoksijeni (O) (H2O). Nemhaka yokuti zvisungo zveO<unk>H zvine polarity, okisijeni atomu ine mutoro wakaderera uye maatomu maviri ehydrogen ane mutoro wakaderera. Iyi polar chivakwa chemvura inoita kuti ikwanise kukwezva mamwe mamorekuru emvura kuburikidza nehydrogen zvisungo, izvo zvinoita kuti mvura ibatane. Kunetsana kwepamusoro kunobva pasimba rinobatanidza rinokonzerwa nokukwezva kuri pakati pemamorekuru ari pamusoro pemvura. Mvura inonamatirawo sezvo ichikwanisa kunamatira kumusoro kwechero polar kana yakabhadharwa isiri mvura mamorekuru. Mvura ine uwandu hwakanyanya kana iri mvura yakasviba kupfuura kana iri mvura yakasimba (kana kuti chando). Ichi chinhu chakasiyana nemamwe chemvura chinoita kuti chando chibhururuke pamusoro pemvura yakaita semadhamu, nyanza, uye makungwa, nokudaro chichidzivirira mvura iri pasi pemvura pamhepo inotonhora iri pamusoro. Mvura inokwanisa kupinza simba, ichiipa simba rakakwirira rinopisa kupfuura mamwe manyoro akadai seethanol. Nokudaro, simba rakawanda rinodikanwa kuputsa zvisungo zvehydrogen pakati pemamorekuru emvura kushandura mvura yakasviba kuva mhute yemvura. Semorekuru, mvura haina kugadzikana zvakakwana sezvo morekuru rimwe nerimwe remvura rinoramba richipatsanuka kuva mahydrogen nemahydroxyl ions risati rachinja kuva morekuru remvura zvakare. Mumvura yakachena, uwandu hwehydrogen ions hunoenzanisa (kana kuti hunoenzana) nehuwandu hwehydroxyl ions, zvichiita kuti pH isapinda.
Mvura inoitwa kuti ibatane nemhaka yechimiro chayo chepolar chinoibvumira kukwezva mamwe mamorekuru emvura kupfurikidza nehydrogen bonds.
