2. hydrogen bonds are weak
3. Ionic bonds are weak
Carbon can be used in fuel
Answer:
HFusion*mass + Spec.Heat*mass*ΔT + HVap*mass
80cal/g*50.0g + 1.00cal/g°C*50.0g*(100°C-0°C) + 540cal/g*50g
3.60x10⁵cal
Explanation:
Using the HFusion we can find the heat needed to convert the ice to liquid water.
With specific heat capacity we can find the heat needed to increase the temperature of water from 0 to 100°C.
With HVap we can find the heat to convert the liquid water into steam.
The equations are:
<h3>HFusion*mass + Spec.Heat*mass*ΔT + HVap*mass</h3><h3 />
Computing the values:
<h3>80cal/g*50.0g + 1.00cal/g°C*50.0g*(100°C-0°C) + 540cal/g*50g</h3>
36000cal =
<h3>3.60x10⁵cal</h3>
