The numbers 200-900 would be confused easily with 22 to 29 if they were used in chemistry. khīlioi = 1000, diskhīlioi = 2000, triskhīlioi = 3000, etc. 13 to 19 are formed by starting with the Greek word for the number of ones, followed by και (the Greek word for 'and'), followed by δέκα (the Greek word for 'ten').
Originally, many thước of varying lengths were in use in Vietnam, each used for different purposes. According to Hoàng Phê (1988), [1] the traditional system of units had at least two thước of different lengths before 1890, [2] the thước ta (lit. "our ruler") or thước mộc ("wooden ruler"), equal to 0.425 metres (1 ft 4.7 in), and the thước đo vải ("ruler for measuring ...
Solutions of at least 50 μM DON in 0.9% NaCl are lightly yellowish. The crystalline form appears as yellowish greenish needles. The specific rotation is [α] 26 D +21° (c = 5.4% in H 2 O). In phosphate buffer, pH 7 are the ultraviolet absorption maxima at 274 nm (E1%1 cm. 683) and 244 nm (E1%1 cm 376). [3] [6]
Vietnamese (tiếng Việt) is an Austroasiatic language spoken primarily in Vietnam where it is the official language. It belongs to the Vietic subgroup of the Austroasiatic language family. [5] Vietnamese is spoken natively by around 85 million people, [1] several times as many as the rest of the Austroasiatic family combined. [6]
The solution has 1 mole or 1 equiv Na +, 1 mole or 2 equiv Ca 2+, and 3 mole or 3 equiv Cl −. An earlier definition, used especially for chemical elements , holds that an equivalent is the amount of a substance that will react with 1 g (0.035 oz) of hydrogen , 8 g (0.28 oz) of oxygen , or 35.5 g (1.25 oz) of chlorine —or that will displace ...
