Answer: The first one: 2.50 x 10^-5
Explanation:
The only true statement about an exterior angle of a triangle from the above is that it forms a linear pair with one of the interior angles of the triangle.
<h3>What is a triangle?</h3>
A triangle can be defined as a one of the plane shapes which has three sides and three angles
So therefore, the only true statement about an exterior angle of a triangle from the above is that it forms a linear pair with one of the interior angles of the triangle.

Answer:
38.2836 kJ
Explanation:
Mass = 91.5g
Initial Temperature = melting point = 0 C = 273 K (upon converting to kelvin)
Final Temperature = Boiling point = 100 C = 373 K
Heat = ?
They are related by the equation;
H = mCΔT
ΔT = Final - Initial Temperature = 373 - 273 = 100 K
C = specific heat capacity = 4.184 J /gK
H = 91.5 * 4.184 * 100
H = 38283.6 J
To convert to kilojoules, divide by 1000. This leaves us with;
H = 38283.6 / 1000 = 38.2836 kJ
Answer:
Hexanal, once commonly called caproic aldehyde, is a six-carbon straight-chain aldehyde. It is a clear liquid with an atmospheric-pressure boiling point of 131 ºC
