The volume of air mattress is = 1.127 L
<u><em>calculation</em></u>
The volume of air is calculated using the ideal gas equation
that is Pv=nRT where,
P(pressure)= 3.5 kilopascals convert into Atm
1 atm =0.00987 KPa
?atm = 3.5 Kpa
= (3.5 kpa x 1 atm) / 0.00987 kpa =354.6 atm
V(volume) = ?
n( no of moles) = 16.5 moles
R (gas constant)= 0.0821 L.atm/mol.K
T(Temperature) = 295 K
make V the subject of the formula V=nRT/P
V= ( 16.5 moles x 0.0821 atm/mol.K x 295 k) /354.6 atm =<u><em>1.127 L</em></u>

<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 ideal gas law is PV= nRT.
First you need to manipulate the equation to splice for volume,
Which will be V= nRT/P
Now you need to input the numbers for each variable. Make sure to remember what the value R equals and it’s units. R= 0.08206 L•atm/n•K
Answer:
![Ka=\frac{[H^+][HCOO^-]}{[HCOOH]}](https://tex.z-dn.net/?f=Ka%3D%5Cfrac%7B%5BH%5E%2B%5D%5BHCOO%5E-%5D%7D%7B%5BHCOOH%5D%7D)
Explanation:
Hello,
In this case, the weak ionization reaction for formic acid is:
In such a way, we simply recall the law of mass action in order to represent the weak ionization constant, Ka, for such process, by taking into account that the concentration of products is divided over the concentration of reactants as shown below:
Best regards.
I would agree with the second one, not the first. You can't always see the chemical reaction, and it isn't always sudden. But the second claim is true.
