Answer:
6
Explanation:
All noble gases are nonreactive, these include helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
Answer:
O2
Explanation:
for find the limiting reactant you must calculate the moles of the reactants from the amount that you have and from the MM:
MM FeS2 = 120n = 26.2g / 120g/mol = 0,218 mol
MM O2 = 32n = 5,44g/32g/mol = 0,17 mol
The limiting reactant is
O2
<span>The two elements that constitute almost three fourths of the earth's solid surface are oxygen and silicon. Oxygen accounts for 46.6 percent of the Earth's crust, while silicon is 27.7 percent. The next more plentiful element on the Earth's crust is Aluminum.</span>
I understand it but the format doesn't make sense to me
Answer:
a) Gold: 5, 2, 2, -1/2
b) Magnesium
: 3, 0, 0, -1/2
c) Iodine: 5, 1, 0, -1/2
d) Cadmium: 4, 2, 2, -1/2
Explanation:
To understand Chemistry in its true sense, it is necessary to know the way the electrons are arranged within the atom and also understand the how and why of the bond and reactivity. To do this, you must first know the how and why of the electronic structure. , this can be done with quantum numbers.
The quantum numbers are four and they help us to describe the place of the electrons in the vicinity of the nucleus.
