In chemistry we often indicate heat in a chemical reaction by using the symbol A instead of writing the word "heat" as part of the reaction. Use this knowledge to identify the following chemical reactions as either endothermic or exothermic. Match the reactions (on the left) with the appropriate terms (on the right). Drag and drop options on the right-hand side and submit. For keyboard navigation...Show More 2C8H18 + 2502 +16CO2 + 18H20+ exothermic A+ AgCl → Ag+1 + C1-1...

Position vs. Time Graphs II Each problem below describes an object moving along a horizontal x-axis. Sketch the position vs. time graph that corresponds to each. "Sketch" means to draw the shape of each graph. Do not attempt to create a scale for the axes of the graphs. a) SLOW constant speed to the RIGHT, b) SLOW constant speed to the LEFT, then SLOW constant speed to the LEFT then FAST constant speed to the RIGHT х c) FAST constant...

For each reaction write a balanced chemical equation and then below the chemical formula of each reactant and product write a brief description of the substance (color and cal state). Also, indicate whether the reaction is exothermic, endothermic, or cannot tell. 3. Single Replacement Reaction Equation: Cu + 2AgNO3 + 2Ag + Cu(NO3)2 Cannot tell Exothermic Endothermic Evidence of Chemical Change: 4.
