Answer:
Fossils are remains or traces from ancient life's that is most likely buried in rocks anywhere in the world. Fossils are basically bones, teeth, shells, nests, leaf impressions, and footprints. That is technically explaining what our planet was like long ago. Some dinosaur fossils have been found. Paleontologists find them almost everywhere. If you don't know what Paleontologists are, they're basically people who study fossils. A lot of fossils are found in sedimentary rocks. Sedimentary is a rock that has been formed from things like sand, mud, and many other kinds of rocks.
Hope this helps.
Answer:
Solid, liquid, gas
Explanation:
add thermal energy to solid and it becomes liquid, add thermal energy to liquid it becomes gas
Answer:
The correct answer is - 0.570 grams
Explanation:
The balanced chemical reaction is given by
Cu(NO3)2(aq) + 2NaOH(aq) --------> Cu(OH)2(s) + 2NaNO3(aq)
1.0 mole 2.0 mole 1.0 mole 2.0 mole
number of mol of Cu(OH)2,
n = Molarity * Volume
= 
millimoles
As clear in the equation, 1 mole of Cu(NO3)2 gives 1 mole of Cu(OH)2
, So, 5.845 millimoles of Cu(NO3)2 will produce 5.845 millimoles of Cu(OH)2
Mass of Cu(OH)2 = number of mol * molar mass
= 
= 0.570 grams
Thus, the correct answer is - 0.570 grams
B) Accurate is the right answer
