Answer:
C. Solid in liquid
Explanation:
Seawater is an example of a solid in liquid solution.
Sea water is made up of:
- water
- mineral salts
- dissolved gases
A liquid solution is always made up of a solute being dispersed within the solvent medium.
The solvent is the liquid or fluid medium.
Such solutions are homogeneous because the solute particles are distributed evenly or uniformly in the solvent.
The solute is usually present in smaller amount compared to the solvent.
Ok let me explain the procedure to you:
The buffer solution is like this:
pH = pKa + log [salt]/[acid]
4 = 4.20 + log [salt] / [acid]
-0.20 = log [salt]/[acid]
If you <span>Solve for [salt]/[acid]
This gives ratio of moles.
</span><span>Take amount of acid be x L and then amount of salt will be 0.1-x
Now molarity*volume=number of moles
</span>I know that with this you will be able to get to the result. Hope this helps
Answer: element
Explanation:
It only has one type of atom making it a element
Answer:
solid
Explanation:
because solid has a definite shape and volume
Answer:
The simplest alkanes have their C atoms bonded in a straight chain; these are called normal alkanes. They are named according to the number of C atoms in the chain.
