Your cousin is preparing a classic volcano for her school's science project using baking soda and vinegar, but she is disappointed that her volcano is not as exciting as the one she saw online. Knowing that you're taking chemistry, she asks for your help. Based on what you learned in experiment 2, which of the following changes is likely to result in the most exciting volcano?A. Combining the reactants in their stoichiometric ratio to ensure maximum production of product.
B. Adding excess vinegar to drive the reaction equilibrium toward products.
C. Using more baking soda, because it is responsible for producing the CO2 gas that erupts from the volcano.
D. Forming the baking soda into a cube so it will react all at once.

The last few miles of the marathon are the most difficult for heather, her hair plastered to her head, sweat clinging to her arms, and her legs already feeling as if they had nothing left, just dead weight. after grabbing a cup of ice water, she feels the ice cubes smash against her nose as she gulps some cool refreshment and keeps on running. in these last few miles, the breeze kicks up and she finally feels some coolness against her skin. drips of sweat, once clinging to her forehead, now spill down, and heather feels more pain as the sweat flows into her eyes. which of the following is the most likely reason why the ice struck heather’s nose when she took a drink? a) water can function as a solvent. b) water can store large amounts of heat. c) water can moderate temperatures through evaporative cooling. d) the density of water decreases when it freezes. e) water has a cohesive nature. sweat remained on heather’s forehead and arms because of the a) high salt content of sweat b) cohesive nature of water c) ability of water to moderate heat d) high evaporative cooling effect of water e) ability of water to act as a solvent
