Answer:
- <em>The relationship between the scale divisions marked on the graduated cylinders and the estimated uncertainty in the volume measurements is</em> that <u>the larger the divisions the larger the uncertainty, and the smaller the divisions the smaller the uncertaintity.</u>
Explanation:
In general, <em>graduated cylinders</em> are marked with divisions (lines) at equal spaces or intervals. There are divisions that show the measure with a number and a series of intermediate not numbered divisions in between two numbered lines.
The <em>uncertainty </em>of the instrument is determined as half the difference between two consecutive marks.
So, the larger the interval of two consecutive marks the larger the uncertainty.

Answer:
Compound is the Nitrosyl Chloride; NOCl
Explanation:
From the Question, we have two X atoms (different elements) bonded to Y.
The central Y atom has one lone pair of electrons.
- A single lone pair can be found with atoms in the nitrogen group such as nitrogen in ammonia
The Y atom is double bonded to an X atom with two lone pairs of electrons.
- Two lone pairs can be found with atoms in the chalcogen group such as oxygen in water
The Y atom is also single bonded to an X atom with three lone pairs of electrons.
- The halogens can carry three lone pairs such as in hydrogen chloride.
Compound is the Nitrosyl Chloride; NOCl
Answer:
I think its C if I'm wrong plz forgive me
2Na(s) + 2H2O(l) = 2NaOH(aq) + H2(g)
