Chemical Reactions and Equations Chemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance

substance formed after a chemical reaction is called product. Chemical Equation: Representation of chemical reaction using symbols of substances is called chemical equation. Chemical Equation is a way to represent the chemical reaction in concise and informative way. Chemical equation can be divided into two types – Balanced Chemical Equation and Unbalanced Chemical Equation. Balanced Chemical Equation: A balanced chemical equation has number atoms of each element equal on both side. According to

fundamental necessity to every human and living thing’s life. The position of the in relationship to the sun‚ Earth determines the time of the year or season. The problem states "assume that at this time of year the sinusoidal axis is at E = -5 degrees." From this statement‚ we could conclude that the time of year this problem took place when daylight is less than half of the day is the winter‚ since the sun shines longer in the summer then it does in the winter. So we assumed that + 5 degrees

laboratory tests made for the Scranton Engineers Club. This formula is given as Where σp is pillar strength‚ σ1 is uniaxial compressive strength of a cubical specimen (w/h = 1)‚ and w and h are pillar dimensions. According to Obert and Duvall‚ this equation is valid for w/h ratios of 0.25 to 4.0‚ assuming gravity-loading conditions. Through back calculations from mining case histories and utilization of laboratory rock properties‚ safety factors of 2 to 4 were derived
