- Which atom bears the formal positive charge in the hydronium ion?arrow_forward4. a) A polyatomic ion of formula SCN is called thiocyanate. Draw a Lewis structure for thiocyanate anion based on the total number of valence shell electrons and a connectivity S-C-N. Show your work b) Next, apply the concept of resonance to arrive at a second resonance form for the ion with formal charge on a different atom. Circle the 2 elements that are Lewis basic in this polyatomic ion. c) Based on your answers above, state which intermolecular attractive forces are important in SCN".arrow_forward1. State Whether following statements are true (T) or False (F) in the space provided. a) Electron geometry and molecular geometry is not the same for all molecules. b) The enthalpy of neutralization of strong acid -strong base reaction is a constant. c) In the ideal gas law equation, the unit of temperature is in Kelvin (K). d) In an endothermic reaction heat is released from the system to the surroundings. e) Both AgCl and PbCl2 precipitates have the same color. contained in a calorimeter. When thermal equilibrium is reached, the temperature of the water is measured to be 30.6 °C. What is the specific heat of the metal?
