Answer:
It is true that a characteristic of rock is that each of the component minerals retains its properties in the mixture.
Explanation:
Rocks are composed of two or more minerals. A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter.
These minerals have been
1) cemented together
2) squeezed and heated together, or
3) melted and cooled together.
One of the most common rock is granite. The four minerals that make up granite are feldspar, quartz, mica, and hornblende. Each of these minerals retain their property in a mixture form in a rock.
He combustion reaction of hexane:
2 C6H14 + 19 O2 = 12 CO2 + 14 H2O
2 mol C6H14 ---------> 12 mol CO2
x mol C6H14 ---------> 18.4 mol CO2
12 * x = 18.4 * 2
12 x = 36.8
x = 36.8 / 12
x = 3.067 moles of CO2
hope this helps!.
Answer:
9.4L
Explanation:
Given parameters:
Mass of Cl₂ gas = 30g
Unknown:
Volume of gas = ?
Solution:
To solve this problem, let us assume that this reaction takes place under standard temperature and pressure conditions.
Therefore;
Volume of gas = number of moles x 22.4
To find the number of moles;
Number of moles =
molar mass of Cl₂ = 2(35.5) = 71g/mol
Number of moles = = 0.42mole
So;
Volume of gas = 0.42 x 22.4 = 9.4L

Lack of clean water
Water should be clean cause we need water so we can drink it cause we live off of it so we need it so it should be clean. Animals need it to survive in the hot so they need it so it should be clean. Insects need it to survive so they need it so it should be clean. THE END
