A should be the answer because the more you test an experiment the more data you have to rely on changing the experiment would cause you to have different outcomes making the results different and unreliable so B, C, and D is not going to be the answer Hope this helps
According to Avogadro's Law, same volume of any gas at standard temperature and pressure will occupy same volume. And one mole of any Ideal gas occupies 22.4 dm³ (1 dm³ = 1 L).
Data Given:
n = moles = ?
V = Volume = 16.8 L
Solution:
As 22.4 L volume is occupied by one mole of gas then the 16.8 L of this gas will contain....
= ( 1 mole × 16.8 L) ÷ 22.4 L
= 0.75 moles
Result:
16.8 L of Nitrogen gas will contain 0.75 moles at standard temperature and pressure.
Answer:
Mass number (A) is the number of nucleons (proton and neutron) present in a atom.
Explanation:
electrons don't cout since they are thousandth's of the mass of protons or neutrons
<span>As pressure increases, so does density. (A direct relationship). Inversely, as temperature increases, density decreases because of increasing volume.
so your answer is DIRECT
hoped it help :D

Answer:
Lab reports are written to describe and analyse a laboratory experiment that explores a scientific concept. They are typically assigned to enable you to: Conduct scientific research. Formulate a hypothesis/hypotheses about a particular stimulus, event, and/or behaviour.
I Suggest going back in the book to look through what you want to use for your presentation as well as your key details and purpose for writing.
Explanation:
