Mr. Holmes is busy making a paper mache volcano that he is sure is going to win the national science fair contest. He only has room in the volcano’s vent to put 100g of baking soda and 100ml of vinegar. Mr. Holmes has 4 different concentrations of vinegar in his lab. The active ingredient in vinegar is acetic acid C2H4O2. Which concentration would give the most intense eruption in the volcano?

Bottle 1 shows that it has 44g of acetic acid in the 1L bottle.

Bottle 2 shows the vinegar has a molarity of 2M acetic acid

Bottle 3 shows it is 4% acetic acid by mass.

Bottle 4 when measured shows a pH of 7.

The allotropes of carbon include a variety of structures that include three-dimensional tetrahedral lattices, planes of hexagonal rings, cylindrical tubes of hexagonal rings, and spheres of five- and six-membered rings. similar shapes of network covalent atomic solids are possible with carbon nitride, boron, and pure silicon (e. g., silicene is a graphene-like allotrope of pure silicon). in contrast, silicates exist as either highly ordered or amorphous (more random) three-dimensional lattices. what could explain why there are there no naturally occurring sheets, stacked sheets, cylindrical tubes, or spheres of network covalent atomic solids composed of silicon and oxygen (sio2)? would pure silicate structures make good lubricants or good electrical conductors?
