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).

? you expect us to answer this? ? this is your schoolwork, i don't think we can with this, i think it would considering being

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

50.23 i believe is correct but don't quote me on that.
