A, It encourages scientists to give convincing evidence for ther results.
Answer:
A mineral is an inorganic solid substance formed naturally in the ground having a definite physical and chemical properties.
The internal atomic structure or arrangmenet of atoms of a mineral determines the chemical and physical properties of the mineral.
For example: diamonds and graphite, atmoic structure of diamond is rigid tetrahedral network providing chemical and physical properties of diamond.
Answer:
violet
Explanation:
just violet
oh and you spelled "COLER" wrong, its color or colour if you live somewhere else
Mass of iron(ll) oxide= 616.608 g
<h3>Further explanation</h3>
Given
Reaction
2Fe+O2 -->2FeO
479.6 grams of iron
Required
mass of iron(ll) oxide
Solution
mol of iron :
= mass : Ar Fe
= 479.6 g : 56 g/mol
= 8.564
From the equation, mol FeO :
= 2/2 x mol Fe
= 2/2 x 8.564
= 8.564 moles
Mass of iron(ll) oxide :
= mol x MW
= 8.564 x 72 g/mol
= 616.608 g
Its definitely gotta be b im pretty sure
