The student is incorrect. Although the amount of copper sulfate dissolved has increased in the new solution, we also have to account for the fact that the amount of water has also increased.
To see whether or not the new solution is more concentrated, we can compare the grams of copper sulfate in each solution to the amount of water in each solution.
Solution A:
Solution B:
Solution A + Solution B:
You'll notice that the concentration for all these solutions is .1 g copper sulfate/1mL
This means that the new solution (A+B) is not more concentrated -- the increase of dissolved copper sulfate was diluted by the additional increase of water, such that the concentration of the new solution was not greater than its component solutions (A and B).
Answer:
Heredity and DNA is the answer
Methyle orange is the indicator that is used in sulfuric acid.
Dimensional analysis is a convenient technique to determine if the solution you're following would lead you to the answer that you're looking for. It is the manipulation of units. Like units are cancelled whenever they appear on the numerator and the denominator side. For example, if the speed is 5 m/s and the time is 2 s, the distance would be:
(m/s)*(s) = m
So, you would know that the solution would be 5*2 because it yields the unit for distance.
Hence, dimensional analysis could prevent crash by calculating the right velocities or distances of the two vessels to prevent collision.
Answer:
The noble gases (Group 18) are located in the far right of the periodic table and were previously referred to as the "inert gases" due to the fact that their filled valence shells (octets) make them extremely nonreactive. The noble gases were characterized relatively late compared to other element groups.
