Calcium phosphate, Ca3(PO4)2, is used to treat calcium deficiencies. What is the molar mass of this compound? The compound PBr_3 is named (a) Potassium bromide (b) Monophosphorus bromide (c) Phosphorus bromide (d) Phosphorus tribromide (e) None of these...
Both components are separated by a ∼100 nm thin silicon nitride membrane (SiNx, 250 × 250 μm lateral length) in the centre of a disposable 35 mm diameter plastic culture dish, through which the electrons can penetrate and interact with the sample that is maintained under atmospheric ...
Most non-metals react directly with heating, such as with sulfur, nitrogen, carbon, hydrogen reaction to calcium sulfide CaS, calcium nitride Ca3N2, calcium carbide CaC2 and calcium hydrogen CaH2, heating reaction with carbon dioxide. [1] Active chemical properties, in the air surface can...
What are the formulas for the following ionic compounds: sodium sulphide, caesium bromide, and magnesium nitride? How many formula units are in 0.761 g of iron(III) nitrate? Calculate the percent by mass of the element listed first in the formula for copper(I) ...
Noticeably, in the MW field, the burger was placed in a boron nitride crucible, which was infilled with a layer of 1 cm thick graphite powders beforehand to avoid spark generation. The crucible containing samples was placed in the corundum tube or in the microwave transparent insulation barrel...
where L is mass loss of the sample heated from 400 °C to 800 °C, m is the initial mass of the carbonated coating before carbonation, D represents the DOC,MCO2MCO2andMγ−C2SMγ-C2Sare the molar mass of CO2and γ-C2S, respectively. ...
