Water Vapor: The Concentration of water vapor varies depending on the air temperature, atmospheric pressure, and amount of humidity (water content) in the air. The highest water vapor concentration is near the equator because more atmospheric convection cycles bring water vapor up from lower altitude...

1 If the concentration of water is high enough,we can assume it is constant(the reaction is first zero-respect to water).In this case,the concentration of methyl formate in water is given by the following expression:[methyl formate]=[methyl formate](0)*e^(-Keff*t)where [methyl formate...

单项选择题The concentration of a certain chemical in a full water tank depends on the depth of the water. At a depth that is x feet below the top of the tank, the concentration is 3 parts per million,where 0<x<4. To the nearest 0.1 foot, at what depth is the concentration equal ...
of brine (sale dissolve in water) is 15%. How many gram(s) of salt is needed to make the concentration to 50%? 相关知识点: 试题来源: 解析 140 加入鹽之後,水是不變量,原來水有200×(1−15%)=170克,那麼新鹽水總重量為170÷50%=340克,含鹽340×50%=170克,鹽共加170−200×15%=140...
g of brine (salt dissolve in water) is 10%. How many gram(s) of brine with concentration 70% is needed to be added so that the concentration will be increased to 45%? 相关知识点: 试题来源: 解析 280 200×(45−10)=y×(70−45) 7000=25y, y=280. 故答案为:280....
