Answer:
A beaker
Step-by-step explanation:
Specifically, I would use a 250 mL graduated beaker.
A beaker is appropriate to measure 100 mL of stock solution, because it's easy to pour into itscwide mouth from a large stock bottle.
You don't need precisely 100 mL solution.
If the beaker is graduated, you can easily measure 100 mL of the stock solution.
Even if it isn't graduated, 100 mL is just under half the volume of the beaker, and that should be good enough for your purposes (you will be using more precise measuring tools during the experiment).
He was testing an acid. So your answer will be C.
Hope this helps!
Zero on a pH scale is very A. acidic, and 14 on a pH scale is very basic.
The lower the number on the scale, the more acidic it is.
Density: Degree of consistency measured by the quantity of mass per unit volume.
Volume: Amount of space something takes up.
Answer:
Neutral (no net charge)
Explanation:
Protons - Positive
Electrons - Negative
Neutrons - No charge
<em>Why? </em>
Neutrons are the particle in an atom with a (as the name suggests) neutral charge. They are neither positive nor negative, unlike protons or electrons.
