An alp-ha particle is equivalent to the nucleus of a helium atom. Helium Atom = Answer.
The shells further away from the nucleus are LARGER and can hold MORE electrons
Answer:
<u><em></em></u>
- <u><em>Concentrated</em></u>
Explanation:
Concentration measures the amount of solute in a solution. There are many expressions of concentration. Some of then are percentage (mass/mass, volume/mass, volume/volume), molarity, molality, mole fraction, among others.
When a solution has a high concentration it is said that it is <em>concentrated; </em>when a solution has a low concentration is is said that is is diluted.
Concentrated solutions expressed in percentage typically have about 80 - 90% (or more) of solute.
Diluted solutions expressed in percentage, tipylcally have about 10% - 20% or less.
But they are not fixed limits. You might say that a 85% solution is concentrated. Acids at 75 % sure are concentrated.
Hence, a 93.3% solution is concentrated, definitely.
This is true there are many factors that influence the amount of a solute.
C₃H₇OH + 4,5O₂ ----> 3CO₂ + 4H₂O
The coefficient for oxygen is 4,5.
