According to the following, how much energy is required to melt two moles of water? H2O (s) ® H2O (l) DHfus= 6.01 kJ/mol
?

Which of the following statements is true about planck’s law

Frictional forces acting on an object are often converted into energy, which causes the temperature of the object to rise slightly.

The reactions shown here can be combined to make the overall reaction c(s) + h2o(g) ⇌ co(g) + h2(g) by reversing some and/or dividing all the coefficients by a number. a. c(s) + o2(g) → co2(g) k=1.363×10^69 b. 2 h2(g) + o2(g) → 2 h2o(g) k=1.389×10^80 c. 2co(g) + o2 (g) → 2 co2(g) k=1.477×10^90
