If I have an unknown quantity of oxygen (O2) at a pressure of 155 kPa, a volume of 34 liters, and a temperature of 87 degrees Celsius, how many GRAMS of gas do I have?

When a spring is compressed, the energy changes from kinetic to potential. which best describes what is causing this change?

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
