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.

Answer:
2) 14.5 moles
Explanation:
The balanced chemical reaction for the formation is:
If 14.5 moles of are produced, is needed to use the stoichiometry of the chemical reaction to calculate how many moles of reacted to form this quantity:
Therefore 14.5 moles of are produced by 14.5 moles of
If you are wanting the equation to be balanced it would be: P4 + 6Cl2 → 4PCl3
Answer: is the limiting reagent, 180 g of water is produced
Explanation:
To calculate the moles :
According to stoichiometry :
1 mole of require 2 moles of
Thus 5 moles of will require= of
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 1 mole of give = 2 moles of
Thus 5 moles of give = of
Mass of
Thus 180 g of will be produced from the given masses of both reactants.
