Explanation:
<u>Physical properties of ZBr₂</u>
The compound is an ionic substance. Therefore it will have properties of ionic compounds. Some of these properties are:
- it is a hard solid usually with high melting points or a liquid with high boiling points.
- Soluble in water and insoluble in non-polar solvents.
- It can conduct electricity in aqueous solutions or in molten form.
- it will undergo a fast reaction.
<u>Z is a metal</u>
To form ionic compound, a metal will combine with a non-metal. Bromine is a non-metal and it is expected that Z will be a metal. This is because ionic bonds involves transfer of electron from one specie to the other. Metals are usually the donor and non-metals are the receptor. This is how ionic bond forms. The electrostatic attraction resulting from the ions produced the ionic bond.
<u>Formula of the oxide</u>
ZO
Z 0
+2 -2
It is obvious that Z has 2 valence electrons. It will lose the two valence electrons to attain stability.
Oxygen requires 2 electrons to resemble Neon. This combination will give a compound ZO.

The total area that could be covered by this roll of tape is 0.1524 m².
<h3>What is the double-sided tape?</h3>
A double-sided tape is a tape that can be stick from both sides. It is used to stick something on a surface. A rectangle is an object that has four sides in which two sides are equal.
If we unroll the tape, we will see that it is a rectangle with dimensions:
length = 6.35 m
width = 1.2 x 10⁻² m
Since the tape has two sides, the total area of the tape is:
A = 2 x (length x width)
A = 2 x 6.35 x 1.2 x 10⁻²
A = 0.1524 m²
Thus, the total area of the tape is 0.1524 m²

It would be 100.60 because we're adding like to the atmosphere it connects to lubricator and then it turns so that's 100.60
Answer:
Explanation:
Synthesis is the combining of two elements or atoms into a compound/mixture. Decomposition is the breaking down of a compound/mixture into individual atoms or elements. In conclusion, on is the building up of a compund/mixture and one is breaking down.
