I hope I’m not wrong on this one but I think chemical changes
Reasoning: I took culinary and we talked more on chemistry than culinary
If I’m wrong sorry
Answer:
True
Explanation:
I think it’s true because the empirical formula of a compound is actually the simplest formula that shows the numerical relationship of the elements in the compound.
hop that helps!
A standard of measurement system is important because it allows scientists to compare data and communicate with each other about their results.
This is because of the increasing number of protons in the nucleus, resulting in a stronger attraction of the electrons with the nucleus.
The question is incomplete. the complete question is:
A chemistry student needs 35.0 g of pentane for an experiment. By consulting the CRC Handbook of Chemistry and Physics, the student discovers that the density of pentane is . Calculate the volume of pentane the student should pour out.Round your answer to 3 significant digits.
Answer: The volume of pentane the student should pour out is 55.9 ml
Explanation:
Density is defined as the mass contained per unit volume.
To calculate volume of a substance, we use the equation:
We are given:
Density of pentane =
Mass of pentane = 35.0 g
Putting values in above equation, we get:
(Conversion factor: )
Hence, the volume of pentane is 55.9 ml
