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.
The nucleus holds the orders for protein synthesis
Answer:
B. Green solution density is 1.06 g/ml and blue solution density is 1.20 g/ml
Explanation:
Density is given as,
D = Mass / Volume
Red Solution,
D = 25 g / 25 mL
D = 1 g/mL
Green Solution,
D = 26.5 g / 25 mL
D = 1.06 g/mL
Yellow Solution,
D = 28.2 g / 25 mL
D = 1.128 g/mL
Blue Solution,
D = 30 g / 25 mL
D = 1.20 g/mL
This would be an ionic bond
Answer:
3) Br-Br
Explanation:
Polarity occurs between Two atoms of unequal electronegativities.
since Br-Br contain only one atom ( ie.Bromine), they have equal electronegativity. So they can't be polar.
