A compressed spring is the right answer
The charge of an aluminum ion is typically 3+. This is because the element's atomic number is 13, reflecting the fact that it has 13 electrons and 13 protons. The valence shell of aluminum has three electrons, and per the octet rule, these three electrons are lost resulting in just 10 electrons and 13 protons.
How many half lives have elapsed?
actually the formula is like this
A=P(1/2)^(t/h)
P=iniital amount
t=time
h=half life
A=final amount
so
hmm, percent
so P=1 then
A=1(1/2)^(144.6/24.1)
A=1(1/2)^6
A=1/64
A=0.05625
so 5.625% is left
<h3>
Answer:</h3>
327° C
<h3>
Explanation:</h3>
The initial temperature of the gas is 27°C
We need to find the final temperature.
If we assume the initial pressure is y
The final temperature will be 2y
Using the pressure law;
Therefore,
Therefore, the new temperature is 600 K or 327° C
