What is the most important intermolecular force in nf3? This makes the structure of nitrogen trifluoride asymmetrical. Thus, it is a polar molecule. For polar molecules, the type of intermolecular force of attraction that dominates is dipole-dipole force. What is the strongest intermolecular attractive force in SiH4? The intermolecular forces exists among SiH4 molecules is […]

Can a peregrine falcon kill a human? A peregrine has between 4 to 8 times as much mass as a baseball, and can move at twice the speed of a fastball. That’s between 16 and 32 times the kinetic energy of a baseball. It is difficult to estimate the time of the collision accurately, but […]

Why is a propane torch lit inside a hot air balloon? Propane torch is lit inside a hot air balloon during pre-flight preparation because the heat from the touch is needed to heat the cold air inside the balloon, so that the air will expand and become less dense and rise, thus providing a lift […]

How fast is 7 horsepower? How much is 212cc in mph? This engine is a performer right out of the box, and should get your go kart running anywhere from 20 mph all the way up to 35mph in its stock form. How fast can a 1 hp engine go? A 1-horsepower engine couldn’t maintain […]

At what temperature does fusion welding takes place? 900°C Is welding permanent or temporary? Welding is a permanent joint and therefore it is not possible to dismantle the welded parts without partially destroying them. Riveting joint is another permanent joint; while fasteners, cotter joint, knuckle joint, etc. are temporary joints. What are permanent and temporary […]

What is tolerance in a resistor? The tolerance of a resistor is the maximum difference between its actual value and the required value and is generally expressed as a plus or minus percentage value. For example, a 1kΩ ±20% tolerance resistor may have a maximum and minimum resistive value of: Maximum Resistance Value. What are […]

What is principle of a method? Principles: Guiding statements and beliefs based on the approach. Method: a teaching design based on a particular approach. Techniques: teaching procedures that are employed with a particular method. Is principle and approach the same? In lang=en terms the difference between principle and approach. is that principle is to equip […]

What measurement represents volume? Volume is the measure of the amount of space occupied by an object. The standard SI unit of volume is defined by the base unit of length (Figure 3). The standard volume is a cubic meter (m3), a cube with an edge length of exactly one meter. Which choice best describes […]

What is meant by 1 molar solution? A 1 molar (M) solution will contain 1.0 GMW of a substance dissolved in water to make 1 liter of final solution. Hence, a 1M solution of NaCl contains 58.44 g. How do you make 200ml of a 0.1 M solution? How do we make the 0.1 M […]
