Answer:
It's Al 3+ + 3e - → Al
Explanation:
Because three negatively charged electrons are needed to balance the three positive charges on the aluminum ion
Answer: properties
Explanation:
The element which has the properties
Mallablity
Ductility
Lusterous
High electric. Conductivity
High tensile strength is said to be metal.
B
1 mile=4 poles
if 5 poles pass by than she´s going around 1.25 miles per min
rounded up = 1.3 mil/min
N(number of moles)=mass/molar mass
10.5=mass
Na=23 (rounded)
Cl=36 (rounded)
Add it together to get the molar mass
=59
Then refer back to the formula
10.5/59
=0.17796
Round that answer
=0.18 mol
