Chapter 6 – Quantities in Chemical Reactions – Chemistry 12.044 × 10 23 h 2 + 6.022 × 10 23 o 2 → 12.044 × 10 23 h 2 o These coefficients also have the ratio 2:1:2 (check it and see), so this equation is balanced. But 6.022 × 10 23 is 1 mol, while 12.044 × 10 23 is 2 mol (and the number is written that way to make this more obvious), so we can simplify this version of the equation by writing it as Chapter 2 Review-ANSWERS CHAPTER 2 REVIEW.

The equation for the line is $y = 5 + 64.96 x.$ Consider what a perfect linear relationship means: we know the exact value of $y$ just by knowing the value of $x.$ A perfect linear relationship is unrealistic in almost any natural process.
