Answer:
There are 0.195 moles.
Explanation:
1 mol of <em>any gas </em>under STP (meaning 1 atm and 273 K) will occupy 22.4 liters.
With the information above in mind, we can <u>calculate how many moles will occupy 4.38 liters</u>:
- 4.38 L * 1 mol / 22.4 L = 0.195 mol
In 4.38 liters of a gas at STP there will be 0.195 moles.

Explanation:
It is a common observation that a strip of aluminium metal in aqueous copper(II)Sulfate does not show any visible reaction. Aluminium is normally expected to displace copper in solution since it is higher than copper in the electrochemical series.
The reason for this is that aluminium forms an oxide film around its surface which prevents reaction with aqueous copper(II)Sulfate. This oxides film protects the aluminium surface such that it is now unable to react with the aqueous copper(II)Sulfate

What Grant felt was something known as a ‘static current’. Experiencing a light electrical shock when you touch another person, (in this case when Grant touched Olivia) is when electrons move quickly towards the protons.
