Answer:Strong bases: OH-, CH3O-, CN-
Nucleophiles: OH-,CN-, NH2-
Leaving groups: Br-, Cl-, H2O,NH3
Explanation: Strong bases have a greater ability to abstract a proton in an elimination reaction. For instance, the OH- easily abstracts a proton to form water. Nucleophilicity is a kinetic property. It measures the rate at which a specie displaces a leaving group from an alkyl halide Good leaving groups are stable anions or neutral molecules. They are often conjugate bases of strong acids.
The hydroxide ion rarely, or almost never acts as a leaving group in SN2 reactions
Answer:
Temperature and pressure are the two factors which are responsible for change in state of matter.
Solid – In a solid, the attractive forces keep the particles together tightly enough so that the particles do not move past each other. ... In the solid the particles vibrate in place. Liquid – In a liquid, particles will flow or glide over one another, but stay toward the bottom of the container.

Answer:
- Mechanical advantages allows humans to perform tasks much easier in terms of the force they need to apply, but must always obey the conservation of energy.
- Mechanical advantage is a measure of the ratio of output force to input force in a system, used to analyze the forces in simple machines like levers and pulleys.
- A good example is pushing a heavy object up a ramp. It may be easier to push the object up a ramp instead of just lifting it up to the right height, but it takes a longer distance.

The organic particles are molecules. Because of strong covalent bonding in the molecule, organic compounds do not react quickly. Reactions with organic compounds are generally slower than inorganic reactions due to this fact.
Increasing temperature speeds up a reaction because of there being more collisions and those collisions have higher energy. Also the high concentration of the chemicals, particle size and there being a suitable catalyst present. ( Though this process is harmful should it be used in modifying results in food grains and meats.)
