You place 36.5 ml of 0.266 m ba(oh)2 in a coffee-cup calorimeter at 25.00°c and add 56.6 ml of 0.648 m hcl, also at 25.00°c. after stirring, the final temperature is 29.83°c. {assume that the total volume is the sum of the individual volumes and that the final solution has the same density (1.00 g/ml) and specific heat capacity (4.184 j/g°c) as water}. calculate the change in enthalpy, δh, of the reaction (in kj/mol) of water formed. enter the appropriate sign (+/

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
