A sample of hydrogen gas occupies 1.0 L at 760 torr in a balloon. If the temperature is kept constant, which expression represents the volume of hydrogen gas in liters when the pressure is raised to 860 torr?

The agent of mechanical weathering in which rock is worn away by the grinding action of other rock particles is call

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
