Problem 112IE

The mass percentage of chloride ion in a 25.00-mL sample of seawater was determined by titrating the sample with silver nitrate, precipitating silver chloride. It took 42.58 ml of 0.2997 M silver nitrate solution to reach the equivalence point in the titration. What is the mass percentage of chloride ion in seawater if its density is 1.025 g/ml?

Psych class notes #1 March 9, 2016 driving down the highway you have used for the past year, checked the speedometer, rear view mirror, and oncoming traffic but there’s a temporary road blockade in the road, slam on the brakes, and explain to the police officer that your eyes were on the road, paying attention. your expectancy did not correlate with the reality: top down processing attention is the ability to focus on relevant information and blocking out irrelevant information. selectively choosing the informations that are provided. ability to direct and maintain attention is the prefrontal cortex its complexity, neural connection, correlates to how the rest of the brain is connected. enhancing cognitive ability cognitive processing automatic something that’s been habitual, practiced, and now able to perform without a lot of thinking. doesn’t require attention like walking, chewing gum, blinking controlled conscious activity, requires a great deal of attention, and performing something that lacks experience/comfortableness we are cognitive misers because our brains don’t really want to spend that much energy, resources our attention is selective broadbent’s filter theory: multiple messages that we receive goes through a selective filter where specific information is picked out to fill the limited capacity of our decision channel which then leads to making actions upon that decision, a response OR it could be stored in our long­term store. information that is personally relevant to you : passes through the filter. personal encounter, social (faces) or pain will not as easily go past your consciousness. this is called something inattentional blindness when you need to perform a task, so your attention narrows to be able to focus. therefore, you may miss something entirely that’s clearly within our visual field (moonwalking bear) change blindness visual disturbances
