Exploring the Law of Conservation of Mass Sami S. Wright **Introduction** The concept of the conservation of mass was first “developed by Antione Lavoisier” (Plourde 46). Lavoisier concluded that matter cannot be created or destroyed only changed. For example: if an ice cube melts it will change states of matter fr...
As discussed in Module 2, you can tell the difference between an ionic and covalent compound by looking for metals in the chemical formula. If there is a metal (left side of the jagged line on the periodic chart) in the compound, it is an ionic compound. If there are only non-metals (right side of the jagged line on th...
Use the EE or EXP key on that calculator. You will have one or the other, but not both. This key has been designed to enter numbers in scientific notation. If you are using the 10x key, then you should stop because that key was not designed for scientific notation. **To enter 3.0 x 108, all you have to type in is ** ...
Yes they do. The distinction is between molecules and atoms. **Molecules** have dots added in pairs. Single dots cannot be present on molecules. Single **atoms** have dots added one at a time according to the rules detailed on page 135 of the chemistry textbook. ...
In this problem, the answer is rounded to 2×103 because of significant figure rules. The T for the water and calorimeter is determined by subtracting 24.2 from 25.1: T = 25.1° C – 24.2° C According to Module 1 (p. 28), the rules for addition and subtraction are DIFFERENT from those of multiplication and division. I...
A figure within a number is significant if it is there to indicate precision. If, instead, it is there just to indicate the size of the number, it is not significant. Thus, a zero to the right of the decimal at the end must always be significant, because that zero does nothing to indicate the size of the number. The nu...
If you had trouble keeping the syrup layer and the water layer separate, don’t worry. This will happen sometimes. The reason has to do with the process of dissolving. The syrup or molasses that you used must have been very soluble in water. Either that, or you must have mixed the solution very vigorously. In any case, ...
When you drop something (like a book), it falls to the ground because it is attracted to the earth. What is meant by the word “attracted” is that gravity exerts a force which pulls the book to the earth. It doesn’t take outside energy for this to happen. The force is supplying the energy necessary. When a solute diss...
It does seem contradictory or incorrect, but the solution color can vary. It goes from bluish/dark purple to light purple/pink. It should be a very clear change. Exact hue and saturation depends on the indicator you made and how many cabbage leaves were used. ...
