options. My unknown compound I was given was green so I knew it had to be either copper (ll) chloride dehydrate or nickel (ll) chloride hexahydrate. After completing the dehydration part of the experiment I found my substance to have a water loss of 45.369%. The value I calculated for the percent water loss of my unknown compound was very close to what the percent water mass of nickel (ll) chloride hexahydrate is. My unknown compound started off as a bright green solid. During the dehydration process

prices of the various commodities sold by the company remained the reason behind this erosion in operating revenue. The contribution of lower prices of these commodities in depressing the revenues was $ 281 million of iron ore fines‚ $ 136 million of nickel‚ $ 98 million of copper and $ 74 million of pellets. Higher volumes of iron ore fines had a positive effect of $ 167 million on the company’s revenue. 53.6 % of the total gross revenue came from Asia out of which China represents more than 70 %.

Nano-Bioreplicated and 3D-Printed Decoys: In order to produce the two types of visual decoys‚ by physical vapor deposition from a female Agrilus planipennis‚ a high fidelity (~200 nm) resolution negative die of nickel was produced. It was then followed by electrodeposition of nickel. Through successive casting and curing of polymers a positive die of epoxy was created from this negative die. Together‚ both of them constituted the mould. Next‚ a poly(ethylene terephthalate) (PET) sheet was used to

care about brownfields. From encouraging urban sprawl through the ‘development’ of greenfields to their environmental impacts on soil‚ air and ground water‚ these properties are a drain upon the urban environment. Redevelopment of brownfields are complicated by the potential contamination of hazardous waste‚ heavy metals and pollution that has been left behind in the soil. Although this land can be used once the soil has been cleaned‚ landowners are not financially incentivized to do so and inevitably
