To determine the mass of the sample in milligrams in this problem, we use the avogadro's number to convert from atoms to moles, relate the moles of element in the sample to the mole present and the molar mass of the sample. We do as follows:
1.552 x 10^22 atoms H ( 1 mol H / 6.022x10^23 atoms H ) ( 1 mol C2H4Cl2 / 4 mol H ) ( 98.96 g C2H4Cl2 / 1 mol C2H4Cl2 ) = 0.625 g C2H4Cl2 = 625 mg <span>C2H4Cl2</span>
Answer: Cu is oxidized while Au is reduced. The oxidizing agent is Au while the reducing agent is Cu

hallo! heres you answer
^Extrusive igneous rocks are formed from the cooling lava that flows above the crust and Intrusive Igneous rocks are formed within the earth's interior.^
is the correct one because
-Intrusive, or plutonic, igneous rock forms when magma is trapped deep inside the Earth. ... Intrusive rocks have a coarse grained texture.
- Extrusive Igneous Rocks: Extrusive, or volcanic, igneous rock is produced when magma exits and cools above (or very near) the Earth's surface.
