Calculate moles of the gases once equilibrium has been re-established. Given volume = 0.70 L, Initial moles of HI(g) = 0.70 moles, moles of I2(g) = 0.10 moles, moles of H2(g) = 0.10 moles
Reaction - H2(g) + I2(g) <--> 2HI(g)
Limestone is another form of CaCO3. Sandstone is primarily silica or sand SiO2. Because of observations made in today's experiment, explain a test that would permit you to distinguish between limestone and sandstone
