Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Kupfuura: Zviratidzo chaizvo zvokupiswa nemakemikari zvinoenderana nemakemikari anobatanidzwa. Zviratidzo zvacho zvinosanganisira kuvava, kuchena kana kuti kusviba kweganda, kunzwa kupisa, kunetseka kufema, kukosora ropa uye/ kana kuti kuora kwetsandanyama. Zvinhu zvinowanzokonzera kupiswa nemakemikari zvinosanganisira sulfuric acid (H2SO4), hydrochloric acid (HCl), sodium hydroxide (NaOH), lime (CaO), silver nitrate (AgNO3), uye hydrogen peroxide (H2O2). Migumisiro inotsamira pachinhu chacho; hydrogen peroxide inobvisa ganda rakacheneswa, nepo nitric acid ichikonzera kuchinja ruvara kuva yero paganda, uye silver nitrate inobereka mavara matema anooneka. Kupiswa nemakemikari kunogona kuitika nokurova zvakananga muviri, kusanganisira ganda nemaziso, nokufema, uye/kana nokudyiwa. Lipophilic zvinhu zvinopararira zvakanaka mumuviri womunhu, somuenzaniso, hydrofluoric acid, sulfur mustard, uye dimethyl sulfate, zvingasapindura pakarepo, asi panzvimbo pezvo zvinoparira kupisa uye kuzvimba maawa pashure pokubata. Kugadzira makemikoro, kuchera, mushonga, uye minda yebasa yakabatana mienzaniso yemabasa apo kutsva kwemakemikoro kunogona kuitika. Hydrofluoric acid inopinda muropa uye inopindirana necalcium nemagnesium, uye munyu unoguma wavapo unogona kukonzera kumira kwomwoyo pashure pokudya neganda.  Mubvunzo: Sirivha nitrate inoumbwa nei?
