Answer:
a have stripped pattern
Explanation:
did it on edunuity and studied on quizlet
Rocks are heated, metamorphosed, melted,
weathered, sediment is transported, deposited and lithified, then it may be metamorphosed
again in yet another cycle. This recycling of the material of the Earth's crust has
been going on for billions of years, as far back as there is a preserved geologic record
(about 4 billion years). Weathering and erosion at the Earth's surface can break
down rocks into small bits. These can be
deposited as sediments that become sedimentary
rocks. Burial, with rising pressure and temperature, can alter sedimentary (as well as any
other) rocks to form metamorphic rocks.
Continued rise in temperature can eventually melt
rocks and produce magma. Cooling of magmas leads to igneous rocks, etc.
We have a balanced equation:
2 Al+ 3 CuSO4 ⇒ Al2(SO4)3+ 3 Cu
1.85 g Al* (1 mol Al/ 26.98 g Al)* (3 mol Cu/ 2 mol Al)* ( 63.55 g Cu/ 1 mol Cu)= 6.54 g Cu.
(Note that the units cancel out so you get the answer)
6.54 g Cu* (56.6/100)= 3.70 g Cu.
The final answer is 3.70 g Cu~
Answer: Option (D)
Explanation: Chemical weathering refers to the breakdown of minerals and forming new minerals due to the presence of chemical elements. For example, hydrolysis.
Due to the chemical weathering, initially, the minerals will get dissolved and are carried to the streams and oceans. After that, due to the saturation by water, the crystals will be precipitated out of that existing solution.
This crystals then sinks down to the bottom, forming sedimentary rocks.
Thus, the correct answer is option (D).
