Formula of a Hydrate Lab Wednesday October 29‚ 2014 Chemistry Honors Purpose This lab was done to determine the percentage of water in a hydrate‚ which was CuSO4 ?H20. Not only the percentage of water can be found‚ the moles of water can be found per one mole of anhydrous salt. An anhydrous salt is a hydrate that lost its water. Using various lab equipment such as burners‚ crucible‚ and balance‚ and techniques such as the mass-to-mole ratio and mass to percentage‚ the percentage of water in a hydrate

strategies and tools to minimise the prominence‚ and further educate teens about contraception. Recently the development of infant simulators to combat this issue has become a popular‚ though expensive solution. With exposure to social media and growing technology‚ teens can gather their attitude towards the effects of teenage parenthood would have on their lives.

Shawn Dubbs Lab 1 The Mole Concept of and the Chemical Formula of a Hydrate Abstract: The objective of this lab was to conduct an experiment to analyze the molar components in alum. This was conducted by heating the alum till the water had evaporated and then determining the number of moles for each component. Then using the these amounts to figure out the empirical formula for alum. Results: In order to determine how much of each separate component a total mass was taken before hand for

physical sensations-sight‚ sounds‚ smells‚ touch‚ and taste-help the infant survive and grow to meet his or her potential. This "somatosensory" bath from a loving caregiver-the rocking‚ hugs‚ coos‚ and smiles-is transformed by the infant’s sensory systems into patterned neuronal activity that controls the development of the brain in positive ways. It is in this dependent relationship between the primary caregivers and the infant that the new form of attachment grows. This attachment the emotional
