<h3>Answer:</h3>

A saturated solution is a chemical solution containing the maximum concentration of a solute dissolved in the solvent.

<h3>Explanation:</h3>
  • A solution is made by dissolving a solute in a solvent.
  • For example dissolving a salt in a solvent such as water results to a solution.
  • Solution may either be saturated or unsaturated.
  • Unsaturated solution is a solution that can dissolve more solute upon addition because it has not reached saturation.
  • A saturated solution on the other hand is a solution that has maximum solute and the concentration of solute is maximum and thus the solvent can not dissolve any more solute.
  • Therefore, a saturated solutions contain maximum concentration of a solute dissolved in the solute.

Do bases contain hydrogen ions (H+)
Dmitrij [34]

One definition of an acid is a molecule that can donate a H+ ion. So for example if you have an acid such as hydrochloric acid (HCl) in water, HCl will donate it's H+ to the H2O molecule, forming Cl- and H3O+.  

In contrast, a base is a molecule that accepts H+ ions. This means a base such as NH3 reacts with H2O to form OH- and NH4.

So when pH is measured, it is the ratio of H3O+ ions to OH- ions. If there are more H3O+ ions, you then know that there are more acidic molecules in the solution, since they must be giving away their H+ ions.  

So a solution with an acid in it will have more H3O+ ions (which can be described as H+ ions) in it. However, an acid by itself will have nothing to donate H+ ions to.

hope this helps also please make me the brainliest

A chemical reaction occurring in a cylinder equipped with a moveable piston produces 0.601 mol of a gaseous product. If the cyli
netineya [11]

Answer:

4.33 L

Explanation:

Assuming ideal behaviour and that all 0.300 moles of gas reacted, we can solve this problem using Avogadro's law, which states that at constant temperature and pressure:

  • V₁n₂ = V₂n₁

Where in this case:

  • V₁ = 2.16 L
  • n₂ = 0.601 mol
  • V₂ = ?
  • n₁ = 0.300 mol

We <u>input the given data</u>:

  • 2.16 L * 0.601 mol = V₂ * 0.300 mol

And <u>solve for V₂</u>:

  • V₂ = 4.33 L

What is the term for the amount of energy that is needed for a chemical reaction to occur?
cupoosta [38]
<span>This would be the activation energy. This is usually in the form of heat, which allows the reaction to undergo some sort of transition. Many times, enzymes can be used as catalysts to lower the activation energy required for the reaction to take place.</span>
