Concept explainers
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.

- Researchers isolated an unknown substance, X, from rabbit muscle. They determined its structure from the following observations and experiments. (a) Qualitative analysis showed that X was composed entirely of C, H, and O. A weighed sample of X was completely oxidized, and the H2O and CO2 produced were measured. This quantitative analysis revealed that X contained 40.00% C, 6.71% H, and 53.29% O by weight. (b) The molecular mass of X, as determined by mass spectrometry, was 90.00 atomic mass units (u). (c) Infrared spectroscopy showed that X contained one double bond. (d) X dissolved readily in water, and the solution demonstrated optical activity when tested in a polarimeter. (e) The aqueous solution of X is acidic. What is the empirical formula of X?arrow_forwardWhat is 4a?arrow_forwardIntroduction Home Depot's market research shows that they can sell 20-lb. bags of ammonium phosphate, a common fertilizer with the chemical formula (NH4)3PO4, for $9.99/bag. This price has been marked up 6% from the wholesale price that they pay to the manufacturer. You decide to use your knowledge of chemistry to produce your own ammonium phosphate and sell it to Home Depot at 5¢ below the wholesale price. You contact a packager, who agrees to package your product for 29¢ per bag. Ammonium phosphate is produced from ammonia (NH3) and phosphoric acid (H,PO4). Ammonia, in turn, can be produced at a 50% yield via the Haber process, using a mixture of hydrogen (H2) and nitrogen (N2) gases with an iron catalyst. Phosphoric acid is obtained from a naturally occurring mineral called fluorapatite, Cas(PO4)3F, by the following process: fluoroapatite is mixed with silica sand (SiO2) and coke (elemental carbon, C) in an electric furnace. The products are carbon monoxide (CO), tetrafluorosilane…arrow_forward
