LARN 030 C8D2 Start the following in class: 1. Write your journal entry, J30 A, The required topic for today is: a. When multiplying or dividing measurements, why is the result limited to the fewest number of significant figures of any of the contributing mathematical factors? or a. When multiplying or dividing measurements with different numbers of significant figures, why is the calculated result limited in significance to the fewest number of significant figures of any factor being multiplied or divided in the calculation? b. When adding or subtracting measurements with different numbers of decimal places, why is the number of decimal places in the calculated result dependent on  the measurement having the least number of decimal places? 2. Write your second journal entry, J30B. The second required journal topic for today is:      When converting a measurement with one SI prefix to an equivalent measurement using a different SI prefix, why is it helpful to set up the first conversion factor with one unit of the measurement without any...

LARN 029 C8D1 Start the following in class: Concept Mapping Instructions:  The purpose of constructing a concept map is to challenge you to think about the relationships between the various listed terms, not to grade you on what you write. Do not give term definitions; we are making a concept map showing some of the relationships between the chemistry terms, not a vocabulary sheet. Be sure to draw a circle, oval, or box figure around each of the given terms. Connect related terms with arrows that have an arrow head. Express the relationship between the two terms in a sentence. Think of a verb or verb phrase that relates each subject word at the tail of the arrow to the object or predicate nominative word at the head of the arrow.. Draw the arrow from the subject word to the object word to which it is related such that a sentence relating the two terms reads in the direction of the arrow. Check that the subject of each sentence...

LARN 028 C7D4 Start the following in class: 1. Study the first page of the document entitled Temperature Scales, Conversions, SI Usages regarding temperature and then answer the following three questions as your journal focus questions for J28abcd. a. Reflect on how a liquid in glass thermometer responds to an increase in temperature.  Why does a heated liquid expand up the narrow tube within a sealed thermometer? b. How does one convert a Celsius temperature to a kelvin temperature? c. What does kelvin temperature represent on the submicroscopic level? Recognize that the kelvin temperature scale's zero point represents a situation in which molecules have no translational energy and represents absolutely the lowest conceivable temperature. The  zero point of the kelvin temperature scale's is called absolute zero.  Know the relationship between the kelvin temperature scale used in the SI and the often used Celsius temperature scale and be able to convert temperatures from one scale to the other readily. [Hint: The numerical value on the kelvin...
