Answer:
Different types of rocks have different chemical composition.
Explanation:
Rock can be distinguished from each other by their chemical composition which is a product of the minerals they contain.
- A rock is an aggregate of minerals.
- Different suites of rocks have their inherent mineralogical composition and facie.
- This is because, these rocks form under different types of conditions from time to time.
- Igneous rocks form from molten rocks, sedimentary rocks form from pre-existing rocks and metamorphic rocks for under elevated temperature and pressure conditions.
- All these conditions plays important roles in the differentiation of minerals in the rock.
The density of the liquid is 1.3 g/mL.
The mass of the liquid is 0.16 kg = 160 g.
The volume of the liquid is 125 mL.
Density = mass/volume = 160 g/125 mL = 1.3 g/mL
Answer:
the empirical formula of the metal fluoride.
Explanation:
Mass of copper heated = 8.249 g
Mass of copper fluoride formed = 13.18 g
Mass of fluorine gas in copper fluoride = x

Moles of copper :

Moles of fluorine:

For the empirical formula divide the smallest mole of an element with all the moles of elements present in the compound.

The empirical formula of the copper fluoride = 
the empirical formula of the metal fluoride.
