A II and IV only; II and IV only
a) Question 19
The molar ratio is 1 mol acid:2 mol base.
Only Reactions II and IV have that molar ratio.
b) Question 20
We have 0.05 mol KOH.
Only Reactions II and IV have the correct amount of acid to react with 0.05 mol KOH.
Ответ:
reducing water pollution
Explanation:
Water conservation means to manage sustainable natural water resources for the current and future of mankind. Thus "reducing water pollution" will help to achieve the goal of water conservation.
Taking longer showers causes wastage of water. Thus option C is incorrect.
Eating food and drinking water is necessary for the well being of human life but it is unrelated to water conservation. Thus option A and B are incorrect.
