What is this balanced? Al2O3---> Al+O2

saveliy_v [14]

The balanced equation :

2Al₂O₃⇒ 4Al+3O₂

<h3>Further explanation</h3>

Given

Reaction

Al₂O₃⇒ Al+O₂

Required

Balanced equation

Solution

A chemical reaction is said to be balanced if the number of elements involved in the reaction is the same (either the reactants or the products)

The reaction above is said to be unbalanced because the number of elements Al and O in the reactants and products is not the same.

The balancing step

1. Give a coefficient

Al₂O₃⇒ aAl+bO₂

2. Make an equation

Al, left = 2, right = a⇒a=2

O, left = 3, right = 2b⇒2b=3⇒b=3/2

The equation becomes :

Al₂O₃⇒ 2Al+3/2O₂ x2

2Al₂O₃⇒ 4Al+3O₂

what is the relationship between the scale divisions marked on the graduated cylinders and the estimated uncertainty in the volu

AURORKA [14]

Answer:

The relationship between the scale divisions marked on the graduated cylinders and the estimated uncertainty in the volume measurements is that the larger the divisions the larger the uncertainty, and the smaller the divisions the smaller the uncertaintity.

Explanation:

In general, graduated cylinders 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 uncertainty 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.
