Here are my reasonable beliefs
For number 1. what the answer seems to be is C.Than looking are numbers two and three their answers are both B
My reasoning for them is , because if you think about the solid liquid gas's this is a common result in most experiments.also for number two , you have to decrease ( go down ) on the concentration ( hardness ) of the subject to get a more powerful solution
So far as number one , for it to be water the atoms have to be far away from the other moving freely , to be a solid they can barely move at all.
Answer:
B.
Explanation:
When we say "biosphere", we're referring to the atmosphere, geosphere, lithosphere and hydrosphere, and everything in them. You've probably heard of these in class as the "pillars of Earth" or the "pillars of our planet". In other words, when we talk about biosphere we're talking about life.
Organic compounds are all of the compounds that contain carbon, C, in them. You might know that CHNOPS* are the "7 molecules of life", and you might have noticed that Carbon stands first in the list, and that's not because it makes up a mnemonic, Carbon is indeed the most important one in many ways.
*Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus and Sulfur.

Answer:
Explanation:
Well, looking at your units only, considering that every mole has a mass of 180 g., I would do:
360/180=2mol
Water combines with carbon dioxide to produce slightly acidic groundwater
that dissolves limestone and forms caves.
This is because the reaction between water and carbondioxide to form
bicarbonate ions( HCO₃⁻). The bicarbonate ions dissociate into Hydrogen
atoms thereby increasing the acidity.
The acidic environment results in the formation of acidic groundwater that
dissolves limestone and forms caves.

Answer:
Shell or orbitals
Explanation:
Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom
