CHEM 103 Lecture 1: Lecture 1
Document Summary
Ask what has been done and look for patterns. Interesting correlation when there is no cause and effect. To nd volume of co2 heated from 10 to 60 subtract the change in solubility, then. Nd this value on the mass vs volume graph on x axis. Hot plate experiment- by heating water the water gets displaced by co2. More atmospheric co2 increasing global temperatures. 1030, 10300, and 103000 will all be assumed to have 3 significant digits. Look at the first digit to the right of the last significant figure. If this digit is greater than 5, or if it is 5 with any non-zero digits to its right, increase the last significant figure by one. If this digit is less than 5, do not change the last significant figure. For addition or subtraction, the number of decimal places in the result is equal to the number of decimal places in the number that has the fewest decimal places.
