The appropriate title of the scatter plot is solubility curve of sugar
The independent variable is temperature
The dependent variable is mass of sugar in grams that can dissolve in 100 mL of water
The solubility curve is a graph of the amount of solute dissolved in a given volume of solvent against temperature.
The solubility of the solute is plotted on the vertical axis while the temperature is plotted on the horizontal axis.
The independent variable is the temperature while the dependent variable is mass of sugar in grams that can dissolve in 100 mL of water.

Answer:
5.1 billion metric tons of carbon is emitted by U.S as compared to other countries which emits about 32.5 billion metric tons of carbon.

U.S emits about 5.1 billion metric tons of carbon in the atmosphere which contribute in air pollution also helps in rising the temperature of the earth atmosphere because carbondioxide is a green house gas which increases the earth temperature. The main reason of high amount of carbon emission is the high number of industries and more fossil fuels is burnt in the engines of vehicles.
