Balancing chemical equation is always the first step in the calculation involving stoichiometry because most of the necessary conversion factors can be lifted from the balanced equation. In here, the law of conservation of mass should always be observed.Answer and Explanation: The unbalanced reactio...
Answer to: Magnesium metal burns brightly in oxygen gas to produce a whitish-grey powder, magnesium oxide. Write a balanced chemical equation for...
According to Equation (6), the most influential factor is calcium concentration [Ca2+] with a positive effect on the response (+37.08), followed by magnesium concentration [Mg2+] (+3.46) and sodium concentration [Na+] (+1.69), which has a positive but moderate effect on hardness removal. ...
To achieve these “neutralization” conditions, the silica stock solution is diluted in pure water, and the magnesium stock solution is diluted to give the appropriate magnesium concentration either in pure water (if r = 1) or in nitric acid (if r = 0.5), so that [H+]in = [Si]in. ...
While Mg(OH)2 and MgO as easily soluble phases dissolve first, and the reaction equation is shown in Equations (1) and (2) in Section 3.2. Subsequently, the deposition reaction was occurred in this region to produce Ni–P particles, as evidenced by the results in Section 3.1.2. At ...
The PT conversion efficiency (η) of the prepared Ca2+-doped MgFe2O4 NPs (125 µg/mL) aqueous solution was calculated according to the available reference Equation (1) [30,31,32]. The UV–vis spectra and TEM images of the Ca2+-doped MgFe2O4 NPs were observed after four laser on/...
