Answer:
5400 cans
Explanation:
First we convert the total weight, 1 ton, to grams:

Now we need to know the mass of aluminum:

Now we make the relation between the mass of aluminum in 1 ton of the earth's crust and the mass of aluminum per can:

Each column is called a group<span>. The elements in each </span>group have<span> the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons.</span>
Answer : The amount of oxygen gas collected are, 0.217 mol
Explanation :
Using ideal gas equation :

where,
P = pressure of gas =
(1 atm = 760 torr)
V = volume of gas = 5 L
T = temperature of gas = 
n = number of moles of gas = ?
R = gas constant = 0.0821 L.atm/mol.K
Now put all the given values in the ideal gas equation, we get:


Thus, the amount of oxygen gas collected are, 0.217 mol
Answer:Lithium
Explanation:Lithium has 3 protons, and 4 neutrons making it the lightest element that isn't a gas.
Answer:

Explanation:
Oxygen has eight eletrons and six valence electrons, giving it the electron configuration of
