Answer:
This is a desert because there is little precipitation for plant and animal life to thrive.
Explanation:
Tundra is harsh environment because of its cold temperature, so it's definitely not too hot. Swamp temperature should be not too cold or hot. The rainforest should have abundant plant and animal life.
Desert has very low precipitation and low moisture so that not much water can be found around. Water is vital for any plant or animal. Water also helps regulate temperature and make the fluctuation in the environment extreme. The temperature around the desert can be really high at daylight and low at night.
First you need to find the balanced chemical formula.
CuCl₂+2NaNO₃→2NaCl+Cu(NO₃)₂
Then you can find out how much NaCl 31.0g of CuCl₂ should produce using stoichiometry. Divide 31.0g by the molar mass of CuCl₂ (134.446g/mol) to get 0.2306mol CuCl₂. Than multiply 0.2306mol CuCl₂ by 2 to get 0.4612mol NaCl. Than multiply 0.4612mol by the molar mass of NaCl (58.45g/mol) to get 26.95g of NaCl.
that means that 100% yield would give you 26.95g of NaCl so to find percent yield divide 21.2 by 26.95 to get 0.7867 which is 78.7% yield
Therefore the answer is 78.7% yield.
I hope this helps. Let me know if anything is unclear
Answer:
cannot remain at rest under the action of any shear force.
Answer:
Option B: cooling as the lava runs down the mountain
Explanation:
The point R is basically at near the Earth's surface.
Now, we are told that rocks melt underground to form magma. This is a process of formation of igneous rocks. So, in formation of igneous rocks another process that will contribute to formation of rocks at point R is named cooling.
Cooling is a process where the larva runs down the mountain that makes magma hardened and makes it it turn into igneous rock.
