Virtual Chem Lab 6-2 & 6-3 Anonymous CHM/110 June 16‚ 2014 Zamir Deen Virtual Chem Lab 6-2 & 6-3 Ranking Salt Solutions by pH 6-2: Ranking Salt Solutions by pH In this assignment you will be asked to rank aqueous solutions of acids‚ bases‚ and salts in order of increasing pH. This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between

Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

Destin Theus Identifying The Disney Effect 8/30/13 Marley and Me So as a child I have had pets‚ all different types of pets. I’ve had fish‚ frogs‚ and my most favorite dogs. My first dogs name was Tank named after myself as that was my nickname growing up playing little league football. And oh yes I was a heck of a football player. He was a chow and pit bull mix‚ quite big in my eyes. He was a very caring a loving dog. My dad brought me to the pound that summer day and I was sold on him. I taught
