The acceptable measurement of the length of the piece of paper is 3.5 cm.
<h3>What is measuring accuracy of a ruler?</h3>
The measuring accuracy of ruler determines how precise or accurate the length of an object is measured.
The limit of accuracy of a ruler is indicated by how "precisely" you can read the length on that ruler's scale—that is, how well you can estimate between the marks.
In a ruler the distance between the closest marks is 0.1 cm.
This implies that the measuring accuracy of meter rule is 0.1 cm.
The acceptable measurement of the length of the piece of paper is calculated as follows;
length = (3 cm + 4 cm)/2 = 3.5 cm
Thus, the acceptable measurement of the length of the piece of paper is 3.5 cm.

<span>C6H12 = 6x12 + 6x1 = 78.
The equation indicates that 2x78 = 156g benzene will produce 6542kJ.
Using proportions you can then calculate that
x/6542kJ = 7.9g / 156g
x = 331.3kJ = 331300J.
heat = mass x ΔT x 4.18J/g°
ΔT = 331300J / (5691g x 4.18J/g°) = 13.9°
final temp = 21 + 14° = 35°C</span>
The formula for Cs and S is Cs₂S.
For Cs and S,
Ions formed will be Cs⁺ and S²⁻
As cesium belongs to group 1A and sulfur belongs to group 6A. Therefore, the condensed electronic configuration is -
For Cs is [Xe} 6s¹ and for S is [Ne] 3s²3p⁴.
Cs have 1 valence electron and S have 6 valence electrons.
Hence to attain a stable electronic configuration, both two Cs atoms lose one electron and form Cs⁺ and these two electrons will be accepted by one S atom to form S²⁻.
Therefore the formula for the compound is Cs₂S as Cs donate 1 electron and S will accept 2 electrons from Cs.
The formula is Cs₂S.
