Answer:
Solving for the Percent by Volume
The v/v concentration of acetic acid in the stop bath is 24.6%.
Explanation:
To answer the question, we need to identify certain information stated in the question. Let us write down what’s given:
Volume of solute = 160 mL
Volume of solution = 650 mL
Next, we need to determine what is required, in this case, the percent by volume. Now, let us look at the formula:
v/v concentration = (solute volume / volume of the solution) * 100
Solution:
Percent by Volume = (160 / 650) * 100
Percent by Volume = 0.2461538461538462 * 100
Percent by Volume = 24.61538461538462
Rounded off = 24.6%
Therefore, the final answer is 24.6%
Explanation:
Neurofeedback involves trying to change brain wave activity.
<h3>Brain wave</h3>
The human brain is an intricate organ that baffles many scientists today. One design feature of the human brain is its ability to send signals in the form of brain waves when the mind is ar work or in a state of rest. These brain wave activity are braodly categorized into four types, namely;
- beta waves
- alpha waves
- theta waves
- delta waves
Neurofeedback thus occurs when an attempt is made to change from one of the above brain wave types to another.
