Answer:Limitation: They may be more expensive and time consuming than lab experiments. Limitation: There is no control over extraneous variables that might bias the results. This makes it difficult for another researcher to replicate the study in exactly the same way.

Explanation: i hope that helps

What is the difference between elements, compounds and mixtures in terms of particle theory?

zvonat [6]

Element is a single substance, while a compound is the chemical combination of two or more elements, and mixture is the physical combination of two or more elements that can easily be reversed to obtain it's previous state.

Answer:

CHO2- ion

Explanation:

We have the lewis structure of a formate-ion here

This is CHO2-.

The carbon atom is the central atom in the structure. It's the least electronegative atom (C). Carbon has 4 valence electrons. Oxygen has 6 valence electrons.

The carbon will bind with 1 hydrogen atom, this will form 1 single bond, because hydrogen has 1 valence electron.

The carbon will bind with oxygen via a double bond.

Since carbon has only 4 valence electrons, it can only form 1 bond with the other oxygen atom.

There will formed 1 double bond between C and O and 1 single bond between C and O resulting in a negative charged O-atom.

This means there are two resonance structures. for the CHO2- ion
