lead(ii) sulfide. a commercially-important lead ore that occasionally contains silver. graphite: carbon. used in pencils. also as an industrial lubricant. hearty clapping: complete a 7-gem world. hematite: iron(iii) oxide. used in the pigment ochre. i have seen the unicycle. not as tricky to complete as you might think; it just takes some time
some of the hydrogen sulfide will react with metal ions in the water or solid to produce iron or metal sulfides which are not water-soluble. these metal sulfides such as iron(ii) sulfide are often black or brown leading to the color of sludge. pyrrhotite is a waste product of the desulfovibrio bacteria a sulfate reducing bacteria.
planets guide by shadow. the surface is scorching hot and mainly composed of iron with deposits of nickel. like wuo camaron is tide-locked to the blue giant forever "looking into the face of gorgon." with a thin atmosphere of carbon dioxide and hydrogen sulfide. the surface is scorching hot and mainly composed of sulfur with
iron sulfide scale precipitation in the formation matrix and around screens and perforations can decrease production capacity. accumulation of iron sulfide scale in the tubulars can result in reduced well deliverability. the build-up of iron sulfide scale could also interfere with the operation of pumps valves and other associated equipment.
iron(ii) sulfide or ferrous sulfide (br.e. sulphide) is a chemical compound with the formula fe s. in the oil/gas industry iron sulfides are often present in a sour system due to reaction between corrosion products and hydrogen sulfide. they can deposit in the production tubing or on the pipe wall and accumulate in separators.
sulfide (british english also sulphide) is an inorganic anion of sulfur with the chemical formula s 2− or a compound containing one or more s 2− ions. solutions of sulfide salts are corrosive. sulfide also refers to chemical compounds large families of inorganic and organic compounds e.g. lead sulfide and dimethyl sulfide.
iron sulfide has the chemical formula fes hence the name iron (ii) sulfide. there is a wide range of applications of ferrous (ii) sulfide or iron sulfide. it is used in the metallurgical industry in imparting and improving additional mechanical properties of metals and alloys by adding sulfur to the metals in the steel manufacturing industry.
