A xylophone uses mallets that strike the bars to make sounds whereas a Pan Flute uses forced air through columns to produce sound. Select the area of each instrument that will produce the lowest pitch sound that the instruments are capable of making.

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
