<h2><em>More</em><em> </em><em>information</em></h2>

  • <em>an empirical formula</em><em> </em><em>is the simplest formula for a compound </em><em>.</em><em>For</em><em> </em><em>example</em><em>,</em><em> </em><em>H2O2</em><em> </em><em>can be </em><em> </em><em>reduced to a </em><em>si</em><em>mpler</em><em> </em><em>formula</em><em>.</em><em> </em>
  • <em>Determining a Molecular Formula from an Empirical Formula The empirical formula for a compound is P 2 O 5 . Its experimental molar mass is 284 g/mol.</em>
  • <em>For example, the empirical formula of benzene (C5H5) is Qj, - because the mole ratio of carbon am'hydrogen is 1:1.</em>

A standard 10.00 g mass is weighed on an analytical balance 100 times. The average and standard deviation obtained gives 10.12 ±
Mekhanik [1.2K]

Answer:

There was an improvement in accuracy. There was no change in precision.

Explanation:

<em>The average mass after recalibration is closer to the mass of the standard, </em>so the recalibration improved the accuracy<em> </em>(the measurement is closer to an accepted 'true' value).

The standard deviation did not change, so the precision (or how disperse the measurements are) was not affected.

What is the oxidation state of Hg in Hg2Cl2?​
Anna [14]

Answer:

+1

Explanation:

Electrochemistry. In oxidation–reduction (redox) reactions, electrons are transferred from one A redox reaction is balanced when the number of electrons lost by the reductant Hg(l)∣Hg2Cl2(s)∣Cl−(aq) ∥ Cd2+(aq)∣Cd(s).

As is evident from the Stock number, mercury has an oxidation state of +1. This makes sense, as chlorine usually has an oxidation state of -1.
