Which of the following is the weakest bond? (a) H-bond is only an interaction between electronegative element and hydrogen therefore, it is the weakest bond among all. Why is Bond making exothermic? Bond forming is an exothermic process, because it releases energy. In reaction profile diagram, the energy change in a reaction, is the difference […]

What are the 8 lab safety rules? General Laboratory Safety Rules Know locations of laboratory safety showers, eyewashstations, and fire extinguishers. Know emergency exit routes. Avoid skin and eye contact with all chemicals. Minimize all chemical exposures. No horseplay will be tolerated. Assume that all chemicals of unknown toxicity are highly toxic. What are the […]
How is wind speed indicated what is the unit used to define wind speed?
How is wind speed indicated what is the unit used to define wind speed? How is Wind Speed and Direction measured? Wind speed is typically reported in miles per hour, knots, or meters per second. One mile per hour is equal to 0.45 meters per second, and 0.87 knots. Wind direction is typically reported in […]
What is homeostasis in cells?
What is homeostasis in cells? In biology, homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems. This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range). What is homeostatic imbalance […]
What will happen when a force is applied on a moving object against the direction of motion?
What is light quality?
What is light quality? Light quality is the wavelength (in nanometers, nm) within the electromagnetic spectrum; i.e. blue light is 450 nm and red light is 650 nm. Each wavelength has a different packet of radiation or energy (in J mol-1) called photons. What type of light causes damage to plants? UV-B radiation has been […]
What is the IQ rating scale?
Is it cruel not to walk your dog?
Does lifting weights make you shorter?
Does lifting weights make you shorter? Most likely, the myth that lifting weights stunts growth came from concern over kids causing damage to their growth plates if they participate in a strength training program. But it’s not the result of lifting weights correctly. Can you grow taller after 30? Bottom line: Can height be increased? […]
Who is responsible for structure failure?
Who is responsible for structure failure? The most common causes of structural failures are: (1) Poor communication between the various design professionals involved, e.g. engineers involved in conceptual design and those involved in the supervision of execution of works. (2) poor communication between the fabricators and erectors. What are the causes of instability of steel […]
