Descriptive Investigations- involve describing and/or qualifying parts of a natural system.
Comparative Investigations-involve collecting data from different populations/organisms under different conditions (so basically a comparison between the two).
Experimental Investigations- involving experiments to test the data hypothesized.

The PDF that I am sharing will help you understand more about these types of investigations.

Descriptive is when something has a very detailed description usually containing ambitious vocabulary

Comparative is a similar to that of a simile. You can also be comparative when you are personifying things. You are comparing the inatimate object to a human

Experimental is when you try to use different and a variety of methods when writing, you would be broad with your choices and go with a different genre, theme or setting

Calculate the amount in grams of Na2CO3 needed in a reaction with HCl to produce 120g NaCl?
klemol [59]
The balanced chemical reaction is written as :

Na2CO3<span> + 2HCl === 2NaCl + H2O + CO2
</span>
We are given the amount of NaCl to be produced from the reaction. This will be the starting point for the calculations. We do as follows:

120 g NaCl ( 1 mol / 58.44 g) ( 1 mol Na2CO3 / 2 mol NaCl)( 105.99 g / 1 mol ) = 1108.82 g Na2CO3 needed
