How do you know if a solvent is protic or aprotic? 3. “Protic” Solvents Have O-H or N-H Bonds And Can Hydrogen-Bond With Themselves. “Aprotic” Solvents Cannot Be Hydrogen Bond Donors Protic solvents have O-H or N-H bonds. Aprotic solvents may have hydrogens on them somewhere, but they lack O-H or N-H bonds, and therefore […]
What are the three basic ways of measuring ingredients?
What are the three basic ways of measuring ingredients? By now you’ve figured out there are three primary kitchen tools for measuring: measuring spoons, liquid measuring cups, and dry measuring cups. A kitchen scale is also helpful for measuring ingredients, as it can be used to measure pasta that doesn’t fit into measuring cups or […]
Is it safe to do strength training everyday?
Is it safe to do strength training everyday? You need to be hitting the weights at least three days per week. The research says that at the very least, training a minimum of two days per week is needed to maximize muscle growth. What is the most dangerous exercise? 5 Dangerous Lifts Overhead squat. While […]
Is a motorcycle a mechanical energy?
Is a motorcycle a mechanical energy? Mechanical energy usually means the sum of the kinetic energy and potential energy. So when you ride your bike you hope that the muscular (chemical) energy is converted mainly into mechanical energy. Unfortunately friction will produce heat and sound and will reduce the amount of mechanical energy that you […]
What happens when an electron jumps to a higher energy level?
What happens when an electron jumps to a higher energy level? What happens when electrons jump between energy levels? Answer: As electron move away from the nucleus, it gains energy and becomes less stable. When electron jumps from lower energy level to higher energy level, it gains energy from surroundings which is known as absorption […]
Why electric field is created?
Why electric field is created? Electric fields originate from electric charges, or from time-varying magnetic fields. The electric field is defined mathematically as a vector field that associates to each point in space the (electrostatic or Coulomb) force per unit of charge exerted on an infinitesimal positive test charge at rest at that point. What […]
What is the relationship between speed and torque?
What is the relationship between speed and torque? Torque is the rotational equivalence of linear force. Speed measures the distance covered in unit time. The relation between torque and speed are inversely proportional to each other. The torque of a rotating object can be mathematically written as the ratio of power and angular velocity. Why […]

What is removed during freeze drying?
What is removed during freeze drying? OVERVIEW. Freeze drying is the removal of ice or other frozen solvents from a material through the process of sublimation and the removal of bound water molecules through the process of desorption. Which is better canning or dehydrating? Some of the main benefits of canning are: It preserves the […]
