The number of elements that forms a negatively charged ions among the following highlighted elements in the below periodic table has to be identified. Concept Introduction: Atoms tend to gain or lose electrons until they obtain an electron configuration that is the same as that of a noble gas. The neutral atom has equal number of protons and electrons. Gaining or loosing of a electrons of an atoms form ions. Atoms form their ions to attain noble gas configuration. Group IA, IIA and IIIA are metal atoms containing one, two or three valence electrons. These metal atoms lose their valence electrons to get noble gas configuration. Group VA, VIA VIIA are non-metal atoms containing five, six or seven valence electrons. These non-metal atoms acquire electrons to get noble gas configuration. Group IVA group elements have four valence electrons. These elements either gain or lose their electrons to get noble gas configuration.

Question

10.00 g of Compound X with molecular formula C₂Hg are burned in a constant-pressure calorimeter containing 40.00 kg of water at 25 °C. The temperature of the water is observed to rise by 2.604 °C. (You may assume all the heat released by the reaction is absorbed by the water, and none by the calorimeter itself.) Calculate the standard heat of formation of Compound X at 25 °C. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

need help not sure what am doing wrong step by step please answer is 971A During the lecture, we calculated the Debye length at physiological salt concentrations and temperature, i.e. at an ionic strength of 150 mM (i.e. 0.150 mol/l) and a temperature of T=310 K. We predicted that electrostatic interactions are effectively screened beyond distances of 8.1 Å in solutions with a physiological salt concentration. What is the Debye length in a sample of distilled water with an ionic strength of 10.0 µM (i.e. 1.00 * 10-5 mol/l)? Assume room temperature, i.e. T= 298 K, and provide your answer as a numerical expression with 3 significant figures in Å (1 Å = 10-10 m).
