Well protons and neutrons are in the center in the atom, while electrons travel in orbitals outside of the nucleus. The electric charge for protons, neutrons, and electrons are 1, 0, and -1 respectively. the mass for protons and neutrons are 1 amu (atomic mass unit) while the electron is 1/2000 amu.<span>

Lithium is Li
<span>Oxygen gas is O2 </span>
<span>Lithium oxide is Li2O </span>
<span>Unbalanced Equation is Li + O2 --> Li2O </span>
<span>There's one O on right side, 2 Os on left, so make coefficient 2 on right side to balance the oxygens. </span>
<span>Li + O2 --> 2 Li2O </span>
<span>Now balance the lithiums. There are 4 Lis on right side; 1 Li on left, so make Li coefficient 4 to balance the lithiums. </span>
<span>4 Li + O2 --> 2 Li2O </span>
<span>This equation is now fully balanced. </span>
<span>Therefore balanced equation is: </span>
<span>4 Li + O2 --> 2 Li2O</span>
Answer: it is part of newtons second law. so the object to your question would accelerate
Explanation: newtons second law
Answer:
C. hydration number
Explanation:
When we dissolve an ionic compound (a charged species) the charges can <u>interact with the water molecule</u>. In the case of <u>cations</u> (positive charges) the negative <u>dipole</u> of water (generated in the oxygen) will interact with the positive charge at the same time the <u>anions</u> (negative charges) the positive <u>dipole</u> of water (generated in the hydrogen).
The amount of water molecules that can interact with a single ion (cation or anion) is called <u>hydration number</u>. In the example, we have a hydration number of "4" for the sodium cation.
I hope it helps!
