Answer:
120.0 kJ
Explanation:
- First we convert the given mass of C to moles:
30.00 g C ÷ 12g/mol = 2.5 mol
- The ΔH° value given by the problem, is the heat absorbed when 5 moles of C react.
So when we have<u> half the moles of C</u> (2.5 instead of 5.0), t<u>he heat absorbed will also be half</u>, thus the answer is:
Answer:
The Heat Deflection Temperature (HDT) 126 °F (52 °C)
Density 1.24 g/cm³
Tensile Strength 50 MPa
Flexural Strength 80 MPa
Explanation:.
