Is N a 3 C 6 H 5 O 7 acid, base or neutral when dissolved in water? Is 2-naphthol a... a. strong acid b. weak acid c. weak base d.strong base e.neutral Account for the conjugate base of the acid. What is meant by a strong acid or base? c2h5nh2 ...
and its conjugate acid (nh 4 + ). the structure of the ammonium cation is illustrated below. this autoionization process can be represented by the following equilibrium reaction: 2nh 3 ⇌ nh 2 – + nh 4 + since ammonia generally functions as a relatively weak base, it can be used ...
In an aqueous solution, classify the compound as a strong acid, weak acid, strong base, weak base, or other for NaOH. Which of the following is a weak base? a. NH3 b. Ca(OH)2 c. Ba(OH)2 d. NaOH e. CH3COOH Which of the following is a weak...
aThe catalyst was characterized by NH3-TPD,XRF and XRD. Fig 1 shows that the intensity of loth the weak and the strong acid centers of the nano-ZSM-5 catalyst decreases after modification, especially, the strong acid sites, which cause coke deposition and usually catalyst deactivation, disappear...
Zinc metal complexes have a strong absorption peak between 350 nm ∼ 400 nm, and under the excitation peak of 365 nm wavelength, the complex has a weak emission peak at 540 nm. According to Fig. 2(a) Two emission peaks can be observed at the excitation wavelength at 365 nm. The emis...
Industrial ammonia water is an aqueous solution containing 25% to 28% ammonia. Only a small portion of ammonia molecules in ammonia water react with water to form ammonium ions and hydroxide ions, namely ammonia monohydrate, which is a weak base only present in ammonia water. ...
acid strength and density. Consequently, Cu/LTA displays lower Cu atomic efficiency than Cu/CHA and Cu/AEI, which can also be rationalized by considering differences in their support topology. By carrying out hydrothermal aging to eliminate support Brønsted acid sites, both CuII(NH3)4ion ...
Which of the following is a strong acid in aqueous solution? a. HI b. NH3 c. HOCH2CH2OH d. H3PO4 e. Ba(OH)2 Classify each of the following as a strong acid, weak acid, strong base, or weak base. a. H2SO4 b. NaOH c. HI d. Ba(OH)2 Which of the foll...
The smaller coefficient for T may indicate the relatively weak impact of T on the NH4+. As for the NVCs and Cl−, although the concentrations were lower compared with the other gas- and particle-phase species, one of Mg2+, Na+, or Cl− was included in the regression models, this ...
