Why did the scientist use 2 different methods to create NaCl? 1. They wanted to create a more than just sodium chloride

2. They wanted to see the erlenmeyer flask glow

3. They wanted to obtain a purer product

it's c. elements are placed in rows based on how may valencies electrons have.

if you mean hydrogen and oxygen then water is the product

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
