MH (N2 H4) is a compound formed by nitrogen and hydrogen, which is easy to dissolve in water. it is produced by urea method in industry, and the by-product ten hydrated sodium carbonate is obtained, (1) the preparation solution needs to be carried out in the beaker,Need to use the volume of water,Stir with a glass stick,Also use the glue head dropper,So choose BD;O = HCl HClO,When the reaction occurs with the sodium hydroxide solution,Chlorine reacts with water first,The resulting hydrochloric acid, hydrochloric acid and sodium hydroxide react to generate sodium chloride, sodium chloride and water,So the reactants are chlorine and sodium hydroxide,The products are sodium chloride, sodium chloride and water,You can use the observation method to draw,O;According to the equation of the reaction of chlorine and sodium hydroxide, the ratio of liquid chlorine to caustic soda is: 35.5 × 2: 2 × 40 = 71: 80,O,It can be seen that two parts of sodium hydroxide are need

Flow selection of household front water filter The flow hour is caused by the amount of RO membrane water, which is related to the filtration accuracy. simply, there are too many filtered wastewater, the water resources that were killed by mistake were left as wastewater, and the water approved by the machine was not so much, so it led to a small amount of water. now there is a more advanced 1:1 Wastewater Rate, can increase the amount of water than ordinary water purifiers by 50% ~ 080. 328 '70 this technology can reduce the amount of waste water to save resources, but also increase the filtration accuracy of water flow will not be reduced.
