BRAINLIST + 100 POINTS IF ANSWERED CORRECTLY (( not b and d )) A team of astronomers discovers a new planet with water. They notice that the process of condensation does not seem to be working on this planet. Which statement best explains the state of the water cycle on this newly discovered planet?

The water is gathered in lakes, oceans, or glaciers.
The water is trapped as water vapor in the atmosphere.
Constant rain or snow is falling on the planet's surface.
Water is frozen underground instead of flowing on the surface.

Asolution contains 225 g of sodium chloride, nacl, dissolved in enough water to make a 0.25 l of solution. what is the molarity of the solution?

What type of chemical bond is formed between two atoms of bromine 1. metallic 2. hydrogen 3. ionic 4. covalent

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?
