An environmental scientist performs research to discover what is in the solid garbage of the average American family. She calculates these amounts in kilograms per year. The categones are paper, yard waste, metals, glass, plastics, food scraps, and "other." Which kind of graph should she use to present her finding, and how should the graph be labeled?
O A. She should use a line graph. The x-axis should be labeled "kind of garbage." The y-axis should be labeled "kilograms per year."
O B. She should use a circle graph. Each segment of the graph should be labeled "number of kilograms per year."
O C. She should use a bar graph. The bottom of each bar should be labeled "kilograms per year." The vertical side should be labeled "type of garbage."
OD. She should use a bar graph. The bottom of each bar should be labeled with the category of garbage. The vertical side should have a scale and be labeled "kilograms per year."

Hydrogenation reactions, in which h2 and an "unsaturated" organic compound combine, are used in the food, fuel, and polymer industries. in the simplest case, ethene (c2h4) and h2 form ethane (c2h6). if 140 kj is given off per mole of c2h4 reacting, how much heat (in mj) is released when 12 kg of c2h6 forms?
