Halogens have seven valence electrons and reqires one more electron to complete its octet
Answer:
64 moles
Explanation:
Let us begin by writing a balanced equation for the reaction. This is illustrated below:
2Na + Cl2 —> 2NaCl
From the equation above,
1 mole of Cl produced 2 moles of NaCl.
Therefore, 32 moles of Cl will produce = 32 x 2 = 64 moles of NaCl.
Therefore, 64 moles of NaCl are produced
Answer: Na2CO3 → Na2O + CO2 is already balanced
Explanation:
See answer.
The Plum Pudding Model is a model of atomic structure proposed by J.J. Thomson in the late 19th century. Thomson had discovered that atoms are composite objects, made of pieces with positive and negative charge, and that the negatively charged electrons within the atom were very small compared to the entire atom.
