What is the relative atomic mass of potassium? What is the atomic mass of sodium chloride? What is sodium's mass number? What is the relative atomic mass of thallium? What is the atomic mass of NaOH? What is the atomic number of sodium?
1000 cm3 of the solution contains 2 moles of NaOH Thus, 1 cm3 of the solution contains 21000 moles of NaOH and 200 cm3 of the solution contains 21000× 200 moles of NaOH. That is, the number of moles of sodium hydroxide is 0.4. In order to find the mass of sodium hydroxide required...
2. aluminum reaction with sodium hydroxide sodium aluminate is also formed by the action of sodium hydroxide on elemental aluminium which is an amphoteric metal. the reaction is highly exothermic once established and is accompanied by the rapid evolution of hydrogen gas. 2naoh + 2h2o → 2naalo2...
Subsequently, C2H2 and HCl (V(HCl)/V(C2H2) = 1.15) were fed through filters with GHSV(C2H2) of 180 h−1 at 180 °C. The effluent gas was passed into NaOH solution and a dryer, followed by analysis with a gas chromatograph (PANNA A60, China) equipped with a flame ...

For liquid milk samples, a procedure was proposed based on preconcentration and removal of the matrix, using ionic exchange (Amberlite IRA 743) and elution of molybdenum with 5% (m/v) NaOH. In this case, a 30-fold improvement in the calibration slope was achieved, leading to a detection ...
Crystals of the Calsepa-glycan 1 complex and PHA-E-glycan 2 complex were grown in a reservoir containing 0.1 M HEPES-NaOH (pH 7.5) and 3.0 M NaCl (Index #11) and 0.1 M sodium acetate (pH 4.5) and 25% (w/v) PEG3,350 (Index #41), respectively. Before X-ray ...
The cages and channels in SAPO-34 and SAO-18 not only allow the diffusion of ethylenes and propylenes but also prevent the diffusion of aromatics and higher-molecular-weight products. Therefore, SAPO-34 and SAPO-18 can be used as zeolite catalysts with high selectivity of ethylenes and ...
