If you're unsure of the answer just type it in the comments.

QUESTION:
For the reactivity category, fill in the boxes to indicate how
reactive Helium is . The more filled boxes, the more
reactive Helium is. If helium has 6 valence electrons, how reactive is it?

Also, if all the boxes are filled then helium is very reactive, if not many boxes are filled then its not really reactive.

Just tell me how many boxes I should fill for how reactive the element Helium is!!
Here is the picture:

<h3>Further explanation</h3>

Given

Bromomethane-CH₃Br

Required

The number of atoms

Solution

The empirical formula is the smallest comparison of atoms of compound forming elements.  

A molecular formula is a formula that shows the number of atomic elements that make up a compound.  

The number of atoms in a compound is generally indicated as a subscript after the atom

If a chemical reaction goes to completion, what can we say about the equilibrium constant for that reaction?
aniked [119]

Answer:

A. The equilibrium constant is very large

Explanation:

The equilibrium constant value is the ratio of the concentrations of the products over the reactants. When a chemical reaction goes to completion, that means that all the reactant has turned into products. As the equilibrium constant defines, it is the ratio of the product to the reactant. So at the final stage of the chemical reaction, the equilibrium constant will be very large.
