<span>Aluminum foil is a metal so it has the typycal properties of metals. These are the three most representative properties of metals that aluminum foil exhibit:
</span>
<span /><span /><span>
</span><span>1) It is good conductor of electricity: this property is consequence of the metallic bond, which permits that the outermost electrons of each atom can flow through the entire network of atoms conducting the electricity.
</span>
<span /><span /><span>
</span><span>2) Is is good conductor of heat: this other property of metals is due to transmission of vibration that is carried out between neighboring atoms.
</span>
<span /><span /><span>
3) it is ductile: this property means that the metals can be formed into foils.
</span><span />
<span>Other properties that can be mentioned are: solid at room temperature and mallealble (can form wires)

Because they wanted the crucible to be dry?
Need to know the variable. What changed, the amount of CO2, temp or pressure?
Incomplete question.
To Find :
The volume of 12.1 moles hydrogen at STP.
Solution :
We know at STP, 1 mole of gas any gas occupy a volume of 22.4 L.
Let, volume of 12.1 moles of hydrogen is x.
So, x = 22.4 × 12.1 L
x = 271.04 L
Therefore, the volume of hydrogen gas at STP is 271.04 L.
Answer: Selectivity of mineral nutrients absorbed by roots
Explanation:
The Casparian strip in the plants are waxy coating found in the roots of the plant which helps in absorbing excess of water into the plants.
These strips thickens the walls, thus preventing the excess of soil solution from being pulled by the roots into the central part of the plant.
It helps in selecting the type and amount of nutrient into the plant but the plant having no Casparian strip will reduce the selectivity of the nutrients.
