Answer:2
Step-by-step explanation:
To find the angle of the helicopter, we are going to take advantage of the fact the the sum of the interior angles of a triangle is always 180°. Lets denote that angle with
, so:
Look what we have here: a angle of 90°, so our triangle is a right triangle.
Now, let
be the distance between Amanda and the helicopter. Using the law of sines:
Remember that sine of 90 ° is equal to 1, so:
We can conclude that the distance between Amanda and the helicopter is
2000 feet.
<span>The formula actual yield /
theoretical yield is used to calculate the percent yield of a reaction.
This value is a measure of how much product is produced relative to the what is
supposed to be produced. We calculate as follows:
Percent yield = </span> actual yield / theoretical yield x 100
Percent yield = 695.2 g ( 1 mol / <span>158.034 g) / 5 x 100
</span>Percent yield = 88% <------OPTION C
