What is the difference between actual and theoretical yield?
What is the difference between actual and theoretical yield? Remember, the theoretical yield is the amount of product produced when the entire limiting product is used up, but then actual yield is the amount of product that is actually produced in a chemical reaction. Why is my actual yield higher than theoretical yield? The percent […]

How do plants return water back into the environment?
How do plants return water back into the environment? Plants soak up large amounts of water through their roots.

What’s it called when plants lose water […]
Can you use a 50mm lens for macro?
Can you use a 50mm lens for macro? 50mm lenses work best in capturing typical macro shots. However, these types of macro lenses have their drawbacks. 50mm lenses make subjects appear half “life-size” since they usually feature a 1:2 ratio, and require shooting at a much closer distance. But a 50mm lens is a must […]
