When you open a bottle of soda, bubbles rapidly form and gas fizzes out. What is the best explanation of this? Group of answer choices (a) Gas that was trapped at the top of the bottle between the cap and the surface of the liquid escapes immediately and 'draws' liquid soda as it escapes, creating the illusion of bubbling. (b) The act of opening the bottle 'dislodges' tiny, nearly invisible gas bubbles that were clinging to the side of the container. They quickly condense into larger bubbles and escape. (c) Warm air from outside the bottle heats the soda, decreasing the solubility of the CO2 in the soda and causing it to bubble out. (d) When the bottle is opened, the pressure of CO2 gas above the liquid rapidly drops, which significantly decreases the solubility of CO2 in the soda, causing it to bubble out. (e) H2CO3 in the soda reacts with water vapor in the air, forming CO2 that quickly bubbles out.
Can you please help me solve this problem? I am having trouble figuring out the process to solve this. Water has a molal freezing point constant of 1.86 degrees Celsius kg/mol. Calculate the freezing point of 46.7 grams of Calcium chloride in 150.469 grams of water. Assume complete disassociation.
Winter is here! With winter comes the danger of ice on roads. While this isn't a huge problem in Seattle, it is a very big problem in other cities. To make roads safer for travel many cities use de-icing agents to reduce the freezing point of water and prevent the accumulation of ice. When choosing a de-icing agent cities need to weigh the effectiveness of lowering the freezing point of water with the environmental impacts to water ways and plants. Increasing the concentration of chloride ions can kill the plants near roads, increase the corrosiveness of a city's water supply, and is toxic to some aquatic life. It can even hurt dog's paws when used on sidewalks. Your task is to help Cincinnati, OH decide which de-icer to use in 2021 on its city streets. The city is trying to decide between using 38% m/v aqueous solution of calcium chloride, CaCl2, and a 25% m/v aqueous solution of calcium magnesium acetate, CaMg(C2H3O2)4.
