NaHCO 3 + HCl → NaCl + H 2 O+CO 2 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 ...
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 ...
An α,β-unsaturated acid is a type of α,β-unsaturated carbonyl compound that consists of an alkene conjugated to a carboxylic acid. [3] The simplest example is acrylic acid ( CH 2 =CHCO 2 H ). These compounds are prone to polymerization, giving rise to the large area of polyacrylate plastics.
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 .
Hanoi central station or simply Hanoi station (Vietnamese: Ga Hà Nội) is one of the main stations of Vietnam Railways, serving as the terminus of five of seven active routes in the national network, including the North–South railway (Reunification Express), the Hanoi–Lào Cai railway, the Hanoi–Haiphong Railway, the Hanoi–Đồng Đăng Railway, and the Hanoi–Quán Triều Railway.
Currently Tô Lịch River begins in Nghĩa Đô ward, Cầu Giấy District (south of the Hoàng Quốc Việt road), running the same direction as the Bưởi, Láng and Kim Giang road to the south, southwest and then turns to the southeast and flows to Nhuệ River (opposite the village of Hữu Từ, Vĩnh Quỳnh, Thanh Trì).
The city encompasses an area of 3,359.84 km 2 (1,297.24 sq mi) [3] and as of 2023, a population of 8,587,100. [8] Hanoi had the second-highest gross regional domestic product of all Vietnamese provinces and municipalities at US$51.4 billion in 2022, [ 12 ] behind Ho Chi Minh City .
