b) ch4 + o2 --> co2 +2h2o

c) mnso4 --> mno + so3

d) mg + 2hcl --> mgcl2 + h2

Compare and contrast physical changes with chemical changes.

What is the independent variable in this investigation? mass volume sample number substance density

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
