Chapter 8.13, Problem 8.57YT
Interpretation Introduction

Interpretation:

Whether the LifeStraw filter heavy metals like arsenic, iron and fluoride or not has to be found. “No, the present version does not filter any of the heavy metals”. The sayings of the informed chemist about the phrase of this answer have to be found.

Concept Introduction:

Fluoridation: Fluride present during tooth formation provide caries resistance systematic incorporation of fluride into enamel during development.

The upward adjustment of the concentration of fluride ion in a public health water supply such a way that concentration of fluride ion in water may be consistently maintained at one part per million by weight to prevent dental caries with minimum possibility of causing dental fluorosis.

Toxicity of Heavy metals such as mercury, plutonium and lead are toxic that have known vital (or) beneficial effect on organisms and their accumulation over time in the bodies of animal can cause series illness.

In the synthesis of hexaaminenickel (II) chloride as in the equation below, a student weighed 3.893 g of Nickel(II) Chloride Hexahydrate, dissolved it in water and reacted it with an excess of concentrated ammonia solution. She isolated 2.468 g of the desired product. Nickel(II) Chloride Hexahydrate   +   6 NH3   →    hexaaminenickel (II) chloride   +   6 H2O (Note: The molar mass of Nickel(II) Chloride Hexahydrate is 237.7 g/mol and the molar mass of the hexaaminenickel (II) chloride is 231.7 g/mol.) Calculate the percent yield of the reaction.
You are told by your instructor to go to the stock room and find a bottle of the chemical K3Cl. Does such a compund exist?
A chemist, during the course of an analysis, runs across a chemical composed of carbon, hydrogen, and oxygen in the proportion 1:2:1 and having a six-sided molecular shape. It is probably (a) a pentose, (b) an amino acid, (c) a fatty acid, (d) a monosaccharide, (e) a nucleic acid.
