Calculate the heat required to melt 64.0 g of solid methanol, given that the molar enthalpy of fusion is 3.22 kJ/mol and the molar mass of methanol is 32.0 g.

For each of the following types of reactions, write a general reaction formula in the symbolic form—for example, a + b → ab. single-displacement double-displacement synthesis decomposition

The blackbody curve for a star name zeta is shown below. what is the peak wavelength for this star ?

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
