Internal Assessment (IA) My topic is “To investigate the Internal Controls practices of K.F.C & K&S Supermarket What is Internal Control? Internal control is the process designed to ensure reliable financial reporting‚ effective and efficient operations‚ and compliance with applicable laws and regulations. Safeguarding assets against theft and unauthorized use‚ acquisition‚ or disposal is also part of internal control. Who have Internal Control? The control environment‚ sometimes referred

Cu-Zn voltaic cell used in the experiment. Zinc has higher reactivity and it is more likely to loss electrons. Thus‚ electrons flow from Zn electrode to Cu electrode. Copper stripe is the positive electrode. Zinc stripe is the negative electrode. Reaction happened on each terminal: Positive terminal: Zn-2e-→Zn2+ Negative terminal: 2H+2e-→H2 It is assumed that bubbles (hydrogen gas) will come out from copper electrode. It is assumed that zinc and copper stripes are pure. Classification of variables

An experiment investigating the effects of interference on speed estimates during the Stroop task Nicharee Thamsirisup (Nid) IB Psychology Standard Level Abstract: This experiment is to investigate the effect of color interference in speed estimates of the Stroop task which was first researched by John Ridley Stroop in 1935. This can be investigated by seeing the time difference between the task of identifying colors when color words are printed in the same color as their semantic meaning

CHAPTER # 1 Q.DEFINE CHEMISTRY. A. Chemistry‚ a branch of physical science‚ is the study of the composition‚ properties and behavior of matter. Chemistry is concerned with atoms and their interactions with other atoms‚ and particularly with the properties of chemical bonds. Chemistry is also concerned with the interactions between atoms and various forms of energy Q.DEFINE THE BRANCHES OF CHEMISTRY. * Physical chemistry is the study of macroscopic‚ atomic‚ subatomic‚ and particulate phenomena

cress seeds. Our first petri-dish was allowed to be fully exposed to the light surrounding it‚ while the second was fully wrapped in black paper excluding a 0.5cm slit directed towards the sun. Dependent Variable: Our dependent variable is the reaction/actions to the given conditions‚ for example the growth of the different cress seeds‚ the direction of growth or if it grows at all. Controlled Variable: To keep the test fair we will control the variables by measuring each variable out. Our

Zn(NO3)2 + 2 H2SO4 ? 2 ZnSO4 + 4 HNO3 4 FeSO4 + 2 H2SO4 ? 2 Fe2(SO4)3 + H2 These two reactions happen simultaneously. 2: 4 HNO3 ? 2 H2O + 3O2 + 2 NO The Nitric Acid decomposes in the intense heat produced by the high concentrate Sulphuric Acid used. 3: 2 Fe2(SO4)3 + 2 H2 + 4 NO ? 4 Fe.NO.SO4 + 2 H2SO4 The Fe.NO.SO4 forms a brown ring in the middle of the solution produced by the reaction‚ making it easy to identify the presence of nitrates in the water. 4.

(Name) (Course Name) (Instructors Name) (Date) Summary of chemistry lab report Introduction The two factors which affect the yield of products in a chemical reaction is the amount of starting materials (reactants) and the percent yield of the reaction. Many experimental conditions for example temperature‚ and pressure can be adjusted to increase yield of the desired product‚ in chemical reaction‚ but because chemicals react according to fixed mole ratios( stoichometrically)‚ the only limited

Partnership Partnership is a long-term commitment to operate in business together. The people who own a partnership are called partners. They maintain one set of accounting records and share the profits and losses. Nature of Partnership 1. It is formed to make profits 2. It must obey the law as given in the Partnership Act 1890. If there is a limited partner‚ it must also comply with the Limited Partnership Act of 1907. 3. Normally there can be a minimum of two partners and a maximum of
