Answer:
Different liquid
Explanation:
<em>The independent variable in the investigation is the different liquid given to the plants.</em>
<u>The independent variable in an experimental investigation is the variable that is supplied by the researcher which directly affects the main variable being measured during the investigation. In other words, the independent variable is a variable that directly affects the dependent variable.</u>
In this case, the dependent variable would be growth determining factors in plants such as height, biomass, number of leaves, etc. while the independent variable would be the different types of liquid given to the plants.
Answer:
* Limiting reagent: potassium.
* 
Explanation:
Hello,
In this case, the undergoing chemical reaction is:
In such a way, the reacting moles of chlorine are:
Now, the amount of chlorine gas that would react with 5.00 g of potassium result:
Thus, the chlorine will be in excess and the potassium will be the limiting reagent. Therefore, the mass of excess chlorine turns out:
Best regards.
