Which F Cl Br is most stable? Generally, the singlet is less stable as the triplet has half-filled orbitals which lead to stability. However, whenever a group that can give electrons, they stabilize the singlet by back donation of their lone pair into the vacant orbital of the singlet carbon. Why is Cl more acidic […]
How do you solve for boiling point?
How do you solve for boiling point? The rather simple equation for determining boiling point of a solution: delta T = mKb. Delta T refers to the boiling-point elevation, or how much greater the solution’s boiling point is than that of the pure solvent. The units are degrees Celsius. Kb is the molal boiling-point elevation […]

Are false lashes bad for you?
Are false lashes bad for you? Unfortunately, fake eyelashes may also cause temporary or permanent loss of your real eyelashes. Taking the fake lashes off can break your natural lashes, and even damage the hair follicle. When this happens, your own lashes can fail to grow back. How do you get eyelash extensions off without […]
Which of the following is paramagnetic N2?
Which of the following is paramagnetic N2? The electronic configuration of boron has been shown which tells us that it is paramagnetic. Same applies to nitrous oxide. Is N2+ more stable than N2? Bond order of both N2+ and N2- is 2.5, but according the molecular orbital theory, N2- has more antibonding electrons than N2+. […]
Which force helps swimmers float in water?
Which force helps swimmers float in water? Buoyancy Why is it better for a swimmer to be higher in the water? Wave resistance will be reduced proportionally by any amount of water that can go over the top of the swimmer. This is the reason why swimmers progress better underwater (at approximately a depth of […]
Is smoking once a month OK?
Is smoking once a month OK? A person who smokes one or two cigarettes a few times a month may be less likely to trigger a full-blown addiction to nicotine. However, they are playing with fire by introducing this highly addictive substance into their bodies. Will 1 cigarette a week harm you? Simon Chapman, Emeritus […]
Why do we use microwave for communication?
Why do we use microwave for communication? Uses. Microwaves are widely used for point-to-point communications because their small wavelength allows conveniently-sized antennas to direct them in narrow beams, which can be pointed directly at the receiving antenna. What type of information can be sent by microwaves? Microwaves are used mostly for point-to-point communications systems to […]
What is example of negative work?
What is example of negative work? Negative work follows when the force has a component opposite or against the displacement. Negative work removes or dissipates energy from the system. Two examples: In pulling a box of books along a rough floor at constant velocity, I do positive work on the box, that is I put […]
Where do we use concave and convex mirrors?
Where do we use concave and convex mirrors? Concave mirror is used by dentist, solar furnace, reflector of a torch, etc. Convex mirror is used in rear view mirrors. What do concave and convex mirrors have in common? Similarities between lenses and mirrors A convex lens acts a lot like a concave mirror. Both converge […]
