Using a huge jar and with water colored with die in it you can make clouds. To do this set up the apparatus as shown in the video. Now open up the top valve and blow air into the jar. Now this causes the air inside to be compressed as we are pushing more air into the confined jar. This creates a high pressure inside the ball. To understand how clouds are formed you need to know two concepts. The first concept is that as pressurized gas expands it cools. The second thing is that warm gases can...
This video shows you how to calculate the percentage yield in chemistry. To find the percentage yield, you will need to divide the actual yield by the theoretical yield. Then, multiply it by 100: i.e. % yield = actual yield/theoretical yield x 100. An actual yield is the amount of a substance produced in an actual laboratory experiment. It is based on an actual physical measurement of a quantity. The theoretical yield is the yield as is calculated on paper: i.e. through calculations. Therefor...

Do not discount the "pretty" rocks found along with gold. The sapphires you see are worth many times more than gold. Sapphire (& Ruby, (corundum), is like garnet, a relatively high specific gravity that will catch in a sluice readily. These gems act as gold, they will drop behind a boulder, in bedrock cracks, and set up in the stratiform layers of a bar on the inside bend of a stream. In a perfect (laboratory world) a river bar sets up from front to back: Gold, Platinum, Lead, Iron Ore (black...
