Explanation:
a solvent is what is doing the dissolving. so in this case the water would be your solvent because it is dissolving the salt. does that make sense?

The characteristics of carbon compounds are they exist with different structures in which the atoms are arranged differently and it forms more compounds than other elements combined.
Explanation:
The carbon atom has atomic number 6 which represents the number of electrons. It is represented by C and it is a non- metal. It has 6 protons, 6 neutrons, and 6 electrons. They are smaller in size so that it can fit in to larger molecules.
It is the only element that can form different compounds because each carbon atoms can form four chemical bonds to other atoms.
The structure of carbon atom is represented with its atomic number 6. The first two electrons are present in inner shell and the remaining four are present in the second shell.
The carbon combines with oxygen, hydrogen, and nitrogen to form many molecules for cellular function. Carbon and hydrogen combine to form hydrocarbon chains and rings.
For example the structural formula for Methane (CH4)
The difference between renewable and non-renewable resources is that renewable resources are being made faster, and we have an infinite supply of them, while non-renewable resources take longer to make(like millions of billions of years) and therefore run out easily.
Renewable resources are like solar, hydro, and wind energy. They are basically impossible to get rid of.
Non-renewable resources are like coal. It takes a long time to make and is nearly run out.
The difference is that renewable resources can be remade, on the other hand non renewable cannot be remade

Answer:
P₂ = 0.8 atm
Explanation:
Given data:
Initial pressure = 1 atm
Initial volume = 7 L
Final volume = 9 L
Final pressure = ?
Solution:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = Initial volume
P₂ = Final pressure
V₂ = Final volume
Now we will put the vales in formula.
P₁V₁ = P₂V₂
P₂ = P₁V₁ /V₂
P₂ = 1 atm × 7 L / 9 L
P₂ = 7 atm. L / 9 L
P₂ = 0.8 atm
