as in A → B or A → B + C It could be bimolecular as in 2A → B + C or A + B → C + D Or it could be trimolecular as in 3A → products or A + 2B → products or A + B + C → products In a unimolecular reaction‚ the A molecule gains so much energy from collisions that it eventually falls apart. In a bimolecular reaction‚ two molecules must collide with the correct orientation and sufficient energy for the reaction to take place. In a trimolecular reaction‚ three molecules must collide simultaneously with

What do you think about running barefoot? Runners should not wear shoes because barefoot runners take a smaller collision force to their feet‚ reduces injuries‚ and most importantly how running barefoot is safe. Running barefoot reduces the amount of injuries you get when running. By running barefoot your feet will take a smaller collision force when landing. The article says that the way you step when running barefoot causes less impact to your feet. In other words‚ running in shoes causes a greater

Being careless can be defined as not showing or receiving care. The tendency to be careless is a quality that exists within human beings. It is possible to be careless about yourself and/or others. While too much care can be a problem‚ too little care can also prove to be hazardous. There is no defined amount of a care needed for a person. The amount of care we need is an amount unique to all of us. Problems can arise when you show an extreme amount of care towards others as well as yourself. When

How is the impulsemomentum theorem just a restatement of Newton’s Second Law

The effects of the motion of the particles on these attractions determines the arrangement of the particles in a sample of matter. PLASMA - Electrically charged gas because of extreme temperatures‚ the particles move so quickly that their collisions release electrons from the atoms. - Mixture of electrons and positively charged ions with high kinetic energy is described as the plasma phrase. - Because of its extreme temperature‚ plasma is not common on earth. - The sun and stars are mad

128 people were killed in that midair collision. This accident set the bad record of aviation accident involved more than 100 people. Back in that time‚ ATC only provided separation to aircrafts under Instrument Flight Rules (IFR) but not aircrafts under Visual Flight Rules (VFR) and separation

needed for the current to pass through the wire. Resistance is a measure of how much energy is needed to push the current through something. Resistance occurs when the electrons travelling along the wire collide with the atoms of the wire. These collisions slow down the flow of electrons causing resistance. THE FOUR FACTORS THAT AFFECT THE RESISTNCE OF A WIRE ARE: 1. LENGTH OF WIRE 2. THICKNESS OF WIRE 3. TEMPERATURE 4. TYPE OF METAL AIM: To investigate how the length of a Nichrome wire can

to middle crust collision and lower crust and upper mantle collision‚ which dipped in the opposite direction of the Mohorovicic-offsetting shear zone. These events caused crustal stretching of the lower crust and upper mantle. The upper to middle crust had extensional reactivation of the thrust as well as the formation of new extensional faults and shear zones. When the lower crust came into contact with the upper mantle a more enigmatic collision occurred. The tectonic collision resulted in the
