Producers produce a product
Consumers buy that product
Equation a. C3H8(g) + O2(g) → CO2(g) + H2O(g) + 2220 kj
is endothermic. + 2220 kj
Equation b. 2 Na(s) + Cl2(g) → 2 NaCl(s) + 819kJ
is also endothermic since the overall energy change is positive. + 819kJ
The equation c. PCl5(g) + 67kj → PCl3(g) + Cl2(g) is endothermic since it requires anergy to proceed.
Answer:
Extraction of aluminium
Aluminium ore is called bauxite . The bauxite is purified to produce aluminium oxide, a white powder from which aluminium can be extracted. The extraction is done by electrolysis. The ions in the aluminium oxide must be free to move so that electricity can pass through it.
Alcohol is a pure substance
Answer:
Here's the conversion factor you need:
1 Kilometer = 39370 inches
So, for your question we want to go 405,696 km....
405696 km x 39370 inches/ 1 km = 15972283464 inches
15972283464 inches x 2.54 x10^8 atoms/1 inch = 4.05 x 10^18 atoms
