Throughout the reflection, make sure you have a copy of the Student Guide (PDF or Word) and your data sheet. In your experiment, you answered the question below:

Question: How do you measure mass, volume, and density of various types of objects?

Reflect on the laboratory experiment

Because the rock is irregularly shaped, you used the
method to measure its volume.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
