Across
4.The ideal gas temperature scale is based on the fact that all gases become ideal in the limit of zero pressure.
8.A reaction in which electrons are transferred from a donor (the reducing agent) to an acceptor molecule (the oxidizing agent).
10.The act or process of splitting into parts
11.A molecule may be said to have undergone a “collision” if its interaction with another object results in a change in molecular direction. An impact with that object is obviously a collision. A “near miss” is also a collision if either molecule or both undergo a change in direction.
15.is the quantity of heat that must be absorbed if a certain quantity of liquid is vaporized at a constant temperature.
17.A nuclear reaction in which a heavy nucleus splits spontaneously or on impact with another particle, with the release of energy
18.Any of a class of organic compounds corresponding to the inorganic salts and formed from an organic acid and an alcohol.
21.Gibbs Free Energy
22.Molecular and formula weight
24.The percent composition of a component in a compound is the percent of the total mass of the compound that is due to that component.
25.a concentration unit, defined to be the number of moles of solute divided by the number of liters of solution.
26.Any of numerous organic compounds, such as benzene and methane that contain only carbon and hydrogen.
Down
1.meth, eth, prop, but, pent, hex, hept, oct, non,and dec
2.A chemical reactions produce by an acid which effects leveled upon polyester elastomers
3.the SI unit for energy is the same as the unit of work; Joule (J), Calorie (cal), British thermal unit (Btu), Kilowatt-hour (kWh), and Large-scale units
5.A chemical reaction and its reverse proceed at equal rates
6.Of a chemical reaction or compound occurring or formed with the evolution of heat
7.The amount of a substance per defined space. Concentration usually is expressed in terms of mass per unit volume.
9.a unit of measurement for temperature; Kelvin, Fahrenheit, and Celsius
12.Pressure (the symbol: P) is the force per unit area applied in a direction perpendicular to the surface of an object.
13.the amount of heat per unit mass required raising the temperature by one degree Celsius.
14.A reaction that doesn't require, for example, any catalyst to speed up the reaction, or doesn't need any heat to initiate the reaction it happens by itself.
16.approximately equal to the difference between the energy used to break bonds in a chemical reaction and the energy gained by the formation of new chemical bonds in the reaction.
19.describes a process or reaction in which the system absorbs energy from its surroundings in the form of heat.
20.A number equal to the sum of the atomic masses of the atoms in a molecule.
23.Combining lighter atomic nuclei to form a heavier nucleus, energy are released.
