Answer:
3.5 moles
Explanation:
62.1g x 1 mol/18.002g = 3.449 which is about 3.5 moles
Answer:
Lithium has a melting point of 180.54 C, a boiling point of 1342 C, a specific gravity of 0.534 (20 C), and a valence of 1. It is the lightest of the metals, with a density approximately half that of water. Under ordinary conditions, lithium is the least dense of the solid elements.
Appearance: soft, silvery-white metal
Atomic Number: 3
Atomic Radius (pm): 155
False. They don't borrow electrons at all. They already have their respective electron affinities. This is called as electronegativity, and it's an occurence where it already has its own from its actual structure. It never borrows any electrons at all.
We solve for the number of mols of CO2 given its volume, assuming that it is an ideal gas.
n = PV / RT
Substituting,
n = (1 atm)(15.67 L) / (0.082 L.atm/mol.K)(273.15 K) = 0.7 moles
From the balanced chemical reaction above, we determine the number of O2 moles needed to produce 0.7 moles CO2.
0.7 moles CO2 x (3 moles O2/ 2 moles CO2) = 1.05 moles O2
Then, we multiply this value by 22.4 L/mol
1.05 moles O2 x (22.4 L / mol) = 23.52 L O2
Thus, the answer is the fourth choice.
It would send its neutron to another atom. Therefore, the neutron < the proton, so it would change to a positive ion.
