### Pramonėje plačiai naudojami junginiai
| Formulė | Pavadinimas |
|---|---|
| Ca(OH)₂ | Gesintos kalkės*** (vidutinio stiprumo hidroksidas) |
| Mg(OH)₂ | Silpnasis hidroksidas |
| CaO** | Negesintos kalkės (bazinis oksidas) |
| MgO | Magnezija (bazinis oksidas) |
\*Mg naudojamas kariuomenėje greitai maistui pagaminti, nes Mg oksidacijos reakcijoje išsiskiria didelis šilumos kiekis.
\**Negesintos kalkės gaunamos deginant klintis.
CaCO₃(k) stackrel{> 1000°C}{\longrightarrow} CaO(k) + CO₂(d)
Negesintos kalkės gali būti gaunamos ir kaitinant gipsą, tačiau gamyboje išsiskiria dideli pavojingų teršalų kiekiai.
CaSO₄·2H₂O stackrel{128°C}{\longrightarrow} CaSO₄·0,5H₂O stackrel{163°C}{\longrightarrow} CaSO₄ stackrel{960°C}{\longrightarrow} CaO + SO₂ + 0,5O₂
*Statybinis gipsas*
Negesintos kalkės naudojamos statybose ir kalcio karbidui gaminti, taip pat kaip atmosferos džioviklis.
CaO(k) + CO₂(d) → CaCO₃(k)
*Cemento akmuo*
CaO(k) + 3C(k) stackrel{Δ}{\longrightarrow} CaC₂(k) + CO(d)
CaO(k) + H₂O(s) → Ca(OH)₂(aq)
*Kalkių vanduo*
\***Gesintos kalkės – smulkūs ir purūs šviesiai balti milteliai, kurių tirpumas 0,16 g/100 g vandens esant 20 °C temperatūrai.
**Kalkių pienas** – į pieną panaši suspensija (kietosios medžiagos dalelės pakibusios tirpiklyje).
**Kalkių vanduo** – skaidrus kalcio hidroksido tirpalas, gaunamas nufiltravus kalkių pieną.
Kalkių pienas naudojamas cukraus pramonėje.' (Size = 4000)], CommandType='Text', CommandTimeout='30']

# VERSLO PLANAVIMAS
## Kaip įgyvendinti svajonę, arba „verslo pyrago“ receptas
Niekas taip nepadeda kurti ateities kaip drąsios svajonės.
Šiandien utopija, rytoj – kūnas ir kraujas.“
*Viktoras Hugo (Victor Hugo)*
„Nuostabioms idėjoms reikia ir nutūpimo mechanizmo, ir sparnų.“
*Čarlzas Džeksonas (Charles Douglas Jackson)*
Alfredui Bernardui Nobeliui tebuvo 29 metai, kai jis pateikė prašymą užpatentuoti nitroglicerino ir azoto rūgšties detonatoriaus išradimą. Sudužus indui, 1866 metais Alfredas Nobelis padarė atradimą: nitroglicerinas susigėrė į diatomitą, kuris turėjo apsaugoti indą nuo smūgių. Jis nustatė, kad mišinys, išsaugojęs savo sprogstamąsias savybes, buvo labai stabilus ir su juo buvo lengva dirbti. Taip gimė dinamitas. Nobelių šeimos įmonės, gaminančios dinamitą, buvo steigiamos visoje Europoje, o gamyba išaugo nuo 11 tonų 1867 metais iki 66 000 tonų 1895 metais. A. Nobelis sėkmingai darbavosi ir kitose gamtos mokslų srityse (pvz., distiliavo žibalą). Mirdamas A. Nobelis turėjo iš viso 355 patentus. Didžiulius savo turtus jis perdavė Nobelio premijos fondui, kuris kasmet skiria fizikos, chemijos, medicinos arba fiziologijos, literatūros bei taikos Nobelio premijas tiems, kurie per praėjusius metus daugiausiai nusipelnė žmonijai. Pirmą kartą Nobelio premija buvo įteikta 1901 metais.
