Hydrochloric acid reacts with barium hydroxide according to the equation: 2 hcl (aq) + ba(oh)2 (aq) → bacl2 (aq) + 2 h2o (l) δh = -118 kj calculate the heat (in kj) associated with the complete reaction of 109 grams of hcl (aq).

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.

How is the shape of the poem “peer” connected to its meaning?

Calculate the ph at the equivalence point for the titration of a solution containing 150.0 mg of ethylamine (c2h5nh2) with 0.1000 m hcl solution. the volume of the solution at the equivalence point is 250.0 ml. kb forethylamine is 4.7 × 10−4 .
