If the bowling ball follows the path shown by the arrow in which direction with the pin move struck by the bowling ball

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

To calculate percent by mass, use the equation below: calculate the percent by mass of each element. %n = % %h = % %o = %
