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.

Answer:
He did this by determining how much the cathode rays were bent when he varied the voltage. He found that the mass of the particles was 2000 times smaller than the mass of the smallest atom, the hydrogen atom.
Explanation:
3 <span>copies of H2 are required to balance this chemical equation. Hope it helps</span>
Naproxen is known to be a weak acid. In order to calculate
its ka and pka, use the equation of getting the ph of weak acid which is ph=
-1/2 log [(Ka)(Mwa)]. The Ka value is 3.18x10^-5. The pKa can be obtained
through pKa = - log Ka. The pKa is 4.5.
