- Consider the reaction below:
AgNO3 (aq) + HCl (aq) AgCl (s) + HNO3 (aq)
If the reaction releases 68.0 kJ of energy, how many
kilocalories of energy does it release? (1 cal = 4.184 J) (Round
off decimal to nearest tenths)

they 848.7th. nut the right answer, audi

graph question answered .. you think better when you are relaxed and happy

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
