Answer:
include quartzite and marble
Explanation:
non-foliated rocks are
1. metamorphic rocks
2. they are formed in the surrounding of igneous rocks
3. The environmental condition of formation of non-foliated rocks are that temperature is very high
4. pressure is very low but equal from all direction on igneous rocks
5. The constituent material crystalizes to form large rocks in which atoms are tightly and closely packed. Due to this density of these rocks are also higher.
Example of such rocks are
Quartzite : Its constituent material are mineral quartz and metamorphosed sandstone
Marble : its constituent material are mineral calcite; metamorphosed limestone
Hence, include quartzite and marble is the correct choice.
Answer:
%KCl = 7.05%
%Water = 92.95%
Explanation:
Step 1: Given data
- Mass of KCl (solute): 36 g
- Mass of water (solvent): 475 g
Step 2: Calculate the mass of the solution
The mass of the solution is equal to the sum of the masses of the solute and the solvent.
m = 36 g + 475 g = 511 g
Step 3: Calculate the mass percentage of the solution
We will use the following expression.
%Component = mComponent/mSolution × 100%
%KCl = 36 g/511 g × 100% = 7.05%
%Water = 475 g/511 g × 100% = 92.95%
