Answer:
Reactants
Explanation:
"Starting chemicals", the substances present before a reaction occurs, are called reactants.
The results of the reaction are called products, which you would also have 15.0g.
Answer:
Experiment Question, Independent & Dependent Variable, Null & Alternate Hypothesis
Explanation:
Experiment Question : Whether fine cloth coverage over chicken jars effect flies & their eggs in ambience ?
Independent Variable : The causal variable, ie cloth cover existence on the chicken jar
Dependent Variable : The resultant variable, ie presence of flies & their eggs near jar, meat
Null Hypothesis [H0] : Cloth cover on chicken jar doesn't effects flies' & eggs' presence around jar, chicken.
Alternate Hypothesis [H1] : Cloth cover on chicken jar effects flies' & eggs' presence around jar, chicken.

Explanation:
The KM Theory is the 'micro' molecular description of the behavior of matter. That is, the theory takes into account particle-particle interactions. This is contrast with the 'macro' molecular description of matter that is based upon empirical relationships without taking into account particle - particle interactions.
For example, Charles Law defines the relationship of gas volume as a function of temperature as being direct. That is, an increase in temperature results in an increase in volume of gas. No mention is made of the fact that the increasing temperature is increasing the kinetic energy content of the particles causing an increase in velocity of the particles.
However, application of the principles of the KM Theory takes into account the relationship between kinetic energy and particle velocity in terms of increasing temperature and transfer of energy to specific quantities of matter. Such results are based upon probability concepts that 4 primary reaction factors must come together simultaneously to effect a chemical reaction. These are ...
1. reactive <u>concentration</u> of reactants => C
2. effective collisions occurring (orientation of particles on collisions) => E
3. the interaction of reactive structures by nature => N
4. temperature - energy conditions initiate reaction (activation energy point) => T
These are assumptions are 'reaction factors' (=> C.E.N.T for memory purposes) that must come together simultaneously to effect a reaction. The greatest probability of this occurring is at the temperature condition called the 'Activation Energy'. The relationship that defines this probability is called the Arrhenius Equation k = Ae^-ΔEₐ/RT where k is the kinetic rate constant, A is a proportionality constant, ΔEₐ the Activation Energy and T the Kelvin Temperature.
