Answer:
Alkanes naturally occur in crude oil and are a major component of many fuels and solvents derived from petroleum
There are ALOT because they would always come in and out and they will burst which creates more so techneclly there are infinate
A. <span>the layer of rock and mineral fragments that covers nearly all of Earth's land surface</span>
Balance the equation first:
2 Fe+6 HNO3→2 Fe(NO3)3+3H2
Then calculate mass of Iron :
4.5×3.0×3.5 cm3(1 mL1 cm3)(7.87 g Fe1 ml)=371.86 g Fe
Now use Stoichiometry:
371.86 g Fe×(1 mol Fe55.85 g Fe)×(6 mol HNO32 mol Fe)=19.97 mol HNO3
Convert moles of nitric acid to grams
19.97 mol HNO3×(63.01 g HNO31 mol HNO3)=1258.3 g HNO3
