Breastfeeding vs. Formula Deciding whether to breastfeed or provide formula milk is a major decision amongst new mothers. As simple as it may seem‚ the decision to breastfeed versus formula feed babies can be difficult and one of the most important decisions a mother can make. While there is nothing wrong with giving babies formula milk‚ breastfeeding should be the number one choice for mothers. As breast milk provides more nutrients‚ is naturally produced by mothers and is less expensive

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
