The reaction ab(aq)→a(g)+b(g) is second order in ab and has a rate constant of 0.0164 m −1 ⋅ s −1 at 25.0 ∘ c . a reaction vessel initially contains 250.0 ml of 0.104 m ab which is allowed to react to form the gaseous product. the product is collected over water at 25.0 ∘ c . part a how much time is required to produce 142.0 ml of the products at a barometric pressure of 707.3 mmhg . (the vapor pressure of water at this temperature is 23.8 mmhg .)

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
