Only trace amounts of the synthetic element darmstadtium (atomic number 110) have been obtained. The element is so highly unstable that no observations of its properties have been possible. Based on its position in the periodic table, propose two different reasonable valence electron configurations for this element.
Use condensed formulas or line angle formulas to illustrate the saponification reaction of the fatty acid that is BOTH an OMEGA-6 AND AN 18:2 FATTY ACID
If the pressure exerted by ozone, O3, in the stratosphere is 3.0*10^-3 atm and the temperature is 250 K, how many ozone molecules are in a liter?
In the early days of the periodic table, the 1870s, both silicon and tin were known elements, but germanium was unknown. Using these trends and the densities of silicon and tin that you just obtained, estimate the density of germanium?
A 100.0 mL of acetic acid solution of unknown molarity is titrated with 0.15 M NaOH solution. The titration requires 43.25 mL of the base. Determine the molarity of the acid, CH3COOH.
the temperature of a metal bar rises by 15 C when it absorbs 4.26 kJ of heat. The mass of the bar is 472g. Determine the specific heat of the metal bar.

In an actual experiment, 100 g each of copper and nitric acid are used and 70g of copper(II) nitrate is obtained. In this experiment, what is a) the limiting reactant
In 1986 an electrical power plant in Taylorsville, Georgia, burned 8,376,726 tons of coal, a national record at that time.
What is the big difference between concentrated and aqueous acids, and what role would that difference play in the reaction between 9-fluorenol and sulfuric acid?
oes this result mean that the change in enthalpy of this process must be negative in order for the process to be spontaneous under standard state conditions? How come?
