Answer:
Scale is the right answer
Explanation:
The scale is a sentence that relates distance on the map to distance on Earth
The k is the proportionality constant of the reaction. Graphically, this is the slope of the graph. Since the graph is linear, then there is only 1 value of k. To calculate this, choose two random points in the line. Suppose we use (0.15,10) and (0.30,20), calculate for the slope.
Slope = k = (10 - 20)/(0.15 - 0.30) = 66.67 mL CO₂/g CaCO₃
Use the coefficients in front of each element or compound
in this case 2 1 2
False is the answer
