The reaction between Fes and O2 shown below produces the gas SO,. 4FeS + 702 → 2Fe2O3 + 4802
How many liters of SO2 gas, at STP, will be produced from 3.1 grams of oxygen?
O 1.2
O 2.5
0 3.8
O 7.6

the answer is 8/21

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.

they share a side

step-by-step explanation:

this is the fundamental definition of adjacent angles

they:

1) share a vertex

2) share a side.

point form: (-3,-1)

equation form: x=-3 y=-1
