Solve for the slope of the 9x-8y=3. You get y= 9/8x - 3/8. So your slope is 9/8. Because the line is parallel. You then use point slope formula to get equation of line in y=mx+b form.(slope form). So y-y1=m(x-x1) y-(-7)=9/8(x-6) y+7=9/8(x-6) So y=9/8x -55...

You have an error on the product side of the third reaction. The reaction produces SnCl4. I was wondering what was wrong Haha. Anyway... Hess's Law...Oh Joy! If we look at the given reactions we see that we must flip three of the reactions to produce the...

I mean an error on the second reaction.
