Answer:
2Mg + O₂ ⟶ 2MgO
Explanation:
Step 1. Start with the most complicated-looking formula (O₂?).
Put a 1 in front of it.
Mg + 1O₂ ⟶ MgO
Step 2. Balance O.
We have fixed 2 O on the left. We need 2O on the right. Put a 2 in front of MgO.
Mg + 1O₂ ⟶ 2MgO
Step 3. Balance Mg.
We have fixed 2 Mg on the right-hand side. We need 2 Mg atoms on the left. Put a 2 in front of Mg.
2Mg + 1O₂ ⟶ 2MgO
Every formula now has a coefficient. The equation should be balanced. Let’s check.
<u>Atom</u> <u>On the left</u> <u>On the righ</u>t
Mg 2 2
O 2 2
All atoms are balanced.
The balanced equation is
2Mg + O₂ ⟶ 2MgO

Hey there!
We can tell from the information we are given that the sum of protons and neutrons is 13, there is 6 protons since it is a carbon atom, and there is no charge which means the number of protons is equal to the number of electrons.
6 + n = 13
n = 7
The number of protons is equal to the number of electrons, so there is 6 electrons.
The isotope 13C has 6 protons, 6 electrons, and 7 neutrons.
Hope this helps!
Dimitry Mendeleef
Explanation:
Dimitry Mendeleef developed a table of elements which revealed regularities in elemental properties. He discovered the periodic arrangement of elements in 1869 while playing his game of solitaire.
- John Newlands in in 1863 proposed the idea of a repeating octaves of properties of elements.
- Dimitry Mendeleef described the periodic table or chart in 1869
- The chart was based on the periodic law which states that "chemical properties of elements are a periodic function of their atomic weights".
- In his periodic table, elements were arranged by atomic weights with recurring properties in a periodic manner>
