What are the bond angles in a trigonal planar geometry? Is CO2 trigonal planar? Is PCl3 trigonal planar? What VSEPR shape is represented here? a. Trigonal pyramidal b. Bent c. Trigonal planar d. Tetrahedral What is the molecular geometry (shape) of the phosphorus trichloride molecule, PCl3?
The smallest representative unit of any covalent chemical compound is a single molecule, in which some number of atoms are connected through the sharing of valence electron pairs. A molecule is polar if it has a net dipole momen...
In order to regenerate MTO activity, various divalent metal ions (Co2+, Cu2+, Fe2+, Mg2+, Mn2+, or Zn2+) were then added to the proteins to an approximately two-fold molar excess, followed by MTO activity analysis. As demonstrated in Fig. 2a/b, only the addition of cupric ions ...
Acetonitrile is an organic molecule whose functional group is the nitrile group, composed of a single carbon atom sharing three pairs of electrons with a nitrogen atom. The acetonitrile structure is perfectly linear; the bond angles between the terminal carbon, the central carbon, and the nitrogen...
A549 Dual and A549 Dual KO-RIG-I cells (InvivoGen) were maintained in Dulbecco’s Modified Eagle Medium (Gibco) containing 10% fetal bovine serum, 100 U/ml penicillin, 100 μg/ml streptomycin at 37 °C in a 5% CO2 incubator. A549 Dual and its KO-RIG-I equivalent cells express secret...
. T-47D cell line was purchased from Shanghai Cell Bank of the National Science Academy of China (Shanghai) (Catalog number: TChu 87). All these cells were cultured according to the provider’s instructions and maintained at 37 °C in a humidified atmosphere containing 5% CO2 in air. ...
Catalytic reduction of CO2 over Cu-based catalysts can produce various carbon-based products such as the critical intermediate CO, yet significant challenges remain in shedding light on the underlying mechanisms. Here, we develop a modified triple-stage
What is not a compound? compounds are made up of 2 or more DIFFERENT elements. ...Molecular hydrogen (H2), molecular oxygen (O2) and molecular nitrogen (N2)are not compounds because each is composed of a single element. Water (H2O), carbon dioxide (CO2) and methane (CH4) are compounds...
Answer to: The peptide bond is a) a hydrogen bond b) an ionic bond c) a covalent bond d) a bond between two monosaccharides e) None of the above By...
