Answer:
q1 = mCpΔT
= 18.016g × 1.84J/g.K × (418.15-373.15)
= 1491.72 J
q2 = n×ΔH vap
= 1mol ×44.0kJ/mol
= 44KJ
∴ qtotal = q1+ q2
= 1.498kJ + 44.0kJ
= 45.498KJ

<h3><u>Answer;</u></h3>
Cellulose
<h3><u>Explanation</u>;</h3>
- Cellulose is a polysaccharide and the most abundant organic compound on the Earth's surface.
- <em><u>It is an important organic molecule due to its strong structure which provides a wide variety of functions. </u></em>
- <em><u>Cellulose is a major component of tough cell walls that surround plant cells and is what makes plant stems, leaves, and branches very strong.</u></em>
- The molecules of cellulose are arranged such that they are parallel to each other joined by hydrogen bond. this arrangement forms long structures that combine with other cellulose molecules producing a strong support structure.
Answer:
endothermic
Explanation:
the negative sign of the heat indicates that heat is being drawn into the system, thus endothermic
