<span>60. 4Li(s) + O2(g) >>>>>>>>>>> 2Li2O(s)
moles O2 required = (84 grams Li) * (1 mol Li / 6.941 grams Li) * (1 mol O2 / 4 mol Li) = 3.026 moles O2 required.
PV = nRT, P = 1 atm, V = ?, n = 3.026 moles, R = 0.0821 L*atm/mol*K, T = 273 K
(1 atm)*(V) = (3.026 moles O2) * (0.0821 L*atm/mol*K) * (273 K)
V = 67.82 Liters is the answer.
hope this helps</span>
My answer will be B and D
Protons and neutrons are in the nucleus (the center of an atom), but electrons are not.
Reduction is the general term for the process in which a chemical species gains electrons
The number of electrons attached to an atom or group of atoms increases during a reduction, a type of chemical reaction. One material is provided with electrons by another, which is oxidized as a result of the reduction.
One of the atoms participating in the chemical interaction between two chemicals gains electrons during reduction, which is a type of chemical reaction. The term refers to the element that receives electrons since the element that gains electrons have a lower oxidation state. A chemical species lowers its oxidation number during a half-reaction known as reduction, typically by acquiring electrons.

Answer: The Correct option is A.
Individual elements join together and constitute a compound
Explanation:
This is because Elements refer to a substance that contain a single atom.
Element is a single entity.
Compound is a substance that consist of two or more elements which are chemically join together. Elements make up a compound.
