Why do the metals Co, Rh, and Lr form octahedral complexes (rather than tetrahedral or square planar complexes)? Hint: Look at the placement in the periodic table and the respective electron configurations.
Liquid nitrogen has a density of 0.807 g/mL at -195.8 °C. If 1.00 L of N2(l) is allowed to warm to 25°C at a pressure of 1.0 atm, what volume will the gas occupy.
Consider an experimental run at 273 rm K where the initial number of moles (n_1) is actually 1.00 rm mol, and the final number of moles (n_2) is 2.00 rm mol.
If a piece of Calcite (Calcium Carbonate) is put into the lake, would it tend to dissolve? Calcium carbonate solubility is 10^-8.35 M2, and the measured concentration of calcium ion is 0.1mM (millimolar)
explain why water is not plotted on the delta t versus molecular mass graph in the analysis .(hint:what makes water different from the other 3 solvents?
Element 107 was made by bombarding Bismuth-209 with Chromium-54. One product is a neutron, what is the balanced equation?
If 100.0 mL of NO (at STP) reacts with 400.0 mL of O2 at STP, calculate the partial pressure of NO2 in the final reaction mixture.
A student adds 6.60 of a 0.380 solution to the beaker. How much will the pH change? The of acetic acid is 4.760.
The pressure of a gas is 817 torr at 55°C. The quantity of the gas is fixed and the volume remains constant as the pressure is adjusted to 102 torr. What is the resulting temperature of the gas?
