  2. Sodium bicarbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_bicarbonate

    H 2 CO 3 → H 2 O + CO 2 (g) Sodium bicarbonate reacts with acetic acid (found in vinegar), producing sodium acetate, water, and carbon dioxide: NaHCO 3 + CH 3 COOH → CH 3 COONa + H 2 O + CO 2 (g) Sodium bicarbonate reacts with bases such as sodium hydroxide to form carbonates: NaHCO 3 + NaOH → Na 2 CO 3 + H 2 O

  3. Sodium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydroxide

    2 Al + 2 NaOH + 2 H 2 O → 2 NaAlO 2 + 3 H 2 Sodium aluminate is an inorganic chemical that is used as an effective source of aluminium hydroxide for many industrial and technical applications. Pure sodium aluminate (anhydrous) is a white crystalline solid having a formula variously given as NaAlO 2 , Na 3 AlO 3 , Na[Al(OH) 4 ] , Na 2 O·Al 2 ...

    A key iodine(III) enolate intermediate forms, which then undergoes either nucleophilic substitution (α-functionalization), elimination (dehydrogenation), or rearrangement. Common hypervalent iodine reagents used to effect these transformations include iodosylbenzene (PhIO), [1] Koser's reagent (PhI(OTs)OH), [1] and (dichloroiodo)benzene (PhICl ...

  5. Gallium nitride - Wikipedia

    en.wikipedia.org/wiki/Gallium_nitride

    GaN crystals can be grown from a molten Na/Ga melt held under 100 atmospheres of pressure of N 2 at 750 °C. As Ga will not react with N 2 below 1000 °C, the powder must be made from something more reactive, usually in one of the following ways: 2 Ga + 2 NH 3 → 2 GaN + 3 H 2 [61] Ga 2 O 3 + 2 NH 3 → 2 GaN + 3 H 2 O [62]

  6. Tô Lịch River - Wikipedia

    After the historical floods in early November 2008, people in Hanoi have, since then, seen Tô Lịch river's water "clean" as it was in previous years. [1] Before said floods, Tô Lịch river was diluted down the mud and waste by rainwater, rising yards, rolling flow and fishes. That flood had the Tô Lịch river's water cleaned within a few ...

    Hanoi is served by Noi Bai International Airport, located in Soc Son District, approximately 15 km (9 mi) north of Hanoi. The new international terminal (T2), designed and built by Japanese contractors, opened in January 2015 and is a big facelift for the airport.

  8. Sodium amide - Wikipedia

    en.wikipedia.org/wiki/Sodium_amide

    2 Na + 2 NH 3 → 2 NaNH 2 + H 2. NaNH 2 is a salt-like material and as such, crystallizes as an infinite polymer. [5] The geometry about sodium is tetrahedral. [6] In ammonia, NaNH 2 forms conductive solutions, consistent with the presence of [Na(NH 3) 6] + and NH − 2 ions.

  9. 3-Nitroaniline - Wikipedia

    en.wikipedia.org/wiki/3-Nitroaniline

    3-Nitroaniline is an organic compound with the formula H 2 NC 6 H 4 NO 2. A yellow solid, it is a derivative of aniline, carrying a nitro functional group in position 3. It is an isomer of 2-nitroaniline and 4-nitroaniline. It is used as a precursor to dyes. [1]
