Could a combination of HClO4 and NaClO4 be used to make a buffer solution? Explain why or why not. CH_3NH_2 is a weak base (K_b = 5.0 \times 10^{-4}) and so the salt, CH_3NH_3NO_3, acts as a weak acid. What is the pH of a solution that is 0.0260 M ...
A salt produced from a weak acid and a strong base produces an acidic solution. This is because the conjugate acid of a weak base is a good acid. It acts as an acid by donating protons to the water molecules in the solution thereby producing hydronium ions. Answer and Explanation: Methy...

By coating the film with an electron or hole transfer layer, [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) or 2,2′,7,7′-tetrakis(N,N-di-p-methoxyphenylamine)-9,9′-spirobifluorene (Spiro-OMeTAD) respectively, we observed the charge transfer directly through the fluorescence ...
Balance HCOOH + C2H5NH2 = CH3CH2CONH2 + H2O Using Inspection The law of conservation of mass states that matter cannot be created or destroyed, which means there must be the same number atoms at the end of a chemical reaction as at the beginning. To be balanced, every element in...
For the 3DP film deposition process illustrated in Figure 4b-top, the one-step solvent exchange process was used with the Lewis-base-acid adduct in 4:1 anhydrous DMF:DMSO with precursors MAI (1.5 M) and PbI2 (1.5 M), while the solution was stirred overnight at RT. Figure 4b-top ...
(97.8%). The trace of other products, such as CH4, C2H4,and formic acid, is below the detection limit of the chromatography (Supplementary Fig.11to Supplementary Fig.13). TheG-value of CH3OH production was promoted from 0.1 to 0.9 × 10−7 mol J−1. Because the CO2-to-...
