Answer:

Explanation:

Hi there!

2Pb (no₃) -------> 2Pb + 4no₂ + o₂

Molecular mass of 4no₂ = 184g

Molecular mass of o₂ = 32g

From the reaction;

When 184 g of no₂  was formed 32 g of oxygen was formed.

When 1 g of no₂  was formed 32/184 g of oxygen was formed.

When 11.5 g of no₂  was formed (32/184)*11.5 g of oxygen was formed.

Therefore, when 11.5 g of no₂  was formed 2 g of oxygen was formed.

Hope it helps!

Answer and Explanation:

Greetings!

Let's~answer~your~question!

Triangle~ ABC ~is ~a ~right~ triangle~ with ~its~ right~ angle ~at ~B. ~Therefore,~AC\\is~ the~ hypotenuse~ of~ right~ triangle~ ABC,~ and~ AB ~and ~BC ~are~ the~ legs~ of~ right~\\ triangle ~ABC.

According~ to~ the~ Pythagorean ~theorem,

AB=\sqrt{20^2-16^2}=\sqrt{400-256}=\sqrt{144}=12

Since ~triangle~DEF~is ~similar~ to~ triangle~ ABC,~ with~ vertex ~F ~corresponding~to~ vertex~ C,~ the~ measure\\ of~angle~ \angle F~equals~ the~ measure~ of~ angle~\angle C.

Therefore,~ sinF=sinC. ~From ~the~ side~ lengths~ of ~triangle~ ABC,

sinF=\frac{opposite ~side}{hypotenuse} =\frac{AB}{AC} =\frac{12}{20}=\frac{3}{5}

Therfore, ~sinF=\frac{3}{5}~or~0.6
