Why is the Ph of ethanol 7?
Why is the Ph of ethanol 7? Ethanol’s hydroxyl group causes the molecule to be slightly basic. It is almost neutral like water. The pH of 100% ethanol is 7.33, compared to 7.00 for pure water. This reaction is not possible in an aqueous solution, as water is more acidic, so that hydroxide is preferred […]
What is the next step after radiation for prostate cancer?
What is the next step after radiation for prostate cancer? After radiotherapy or brachytherapy, your PSA should drop to its lowest level (nadir) after 18 months to two years. Your PSA level won’t fall to zero as your healthy prostate cells will continue to produce some PSA. Your PSA level may actually rise after radiotherapy […]
Are there 5 or 6 kingdoms?
Are there 5 or 6 kingdoms? Until recently the system devised by Robert Whittaker in 1968 was widely adopted. Whittaker’s classification scheme recognizes five kingdoms: Monera, Protista, Fungi, Plantae, and Animalia. What are the 3 main domains of life? According to this system, the tree of life consists of three domains: Archaea, Bacteria, and Eukarya. […]

Is there another way of writing a very big or small numbers?
Is there another way of writing a very big or small numbers? Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation […]
Which has more thermal energy?
Which has more thermal energy? If two objects made of the same substance have different masses or temperatures, you can determine which has more thermal energy. If the objects have different masses but are otherwise the same, the one with more mass has more thermal energy. What is thermal power in short? Thermal power describes […]
Is it dangerous to connect two extension cords?
Is it dangerous to connect two extension cords? If you plug two identical cords into each other, that reduces their current capacity in half and can possibly result in voltage drop and overheating. In general, extension cords should not exceed 100 feet in length. However, by plugging one extension cord into another, the maximum cord […]
What is protraction and retraction of shoulder?
What is protraction and retraction of shoulder? Protraction of the scapula occurs when the shoulder is moved forward, as when pushing against something or throwing a ball. Retraction is the opposite motion, with the scapula being pulled posteriorly and medially, toward the vertebral column. What causes protracted scapula? Scapular dyskinesis in impingement is characterized by […]
Why do we need to study dynamics?
Why do we need to study dynamics? As a field of study it is very important for analyzing systems consisting of single bodies or multiple bodies interacting with each other. A dynamics analysis is what allows one to predict the motion of an object or objects, under the influence of different forces, such as gravity […]
