In the PhET simulation window, click the Two Atoms menu in the top left corner of the screen. Click on the partial charges check box to see the partial charges of the atoms. Vary the electronegativity of atom A and atom B and observe the effects on the partial charge of each accordingly. Use the PhET to complete the sentences describing how electronegativity is related to bond dipole experienced by the molecule.
An automobile engine requires a carburetor or fuel inector to mix the fuel with air. The fuel and air must be mixed in a particlar ratio to achieve maximum efficiency in the combustion of the fuel.
The temperature of a 35.2 g sample of iron increases from 23.7 C to 29.5 C. If the specific heat of iron is 0.450 J/g-K, how many joules of heat are absorbed.
You are a hazmat responder and walk into what appears to be a meth lab. There are flasks of iodine, White Gas fuel, Sodium Hydroxide, Nitric Acid, and a box of ephidrine.
Determine the concentration of the total available acid of the apple juice express your answer in moles/L?
If 2.44 moles of Helium gas has a pressure of 2.4 atm at 343 K, what volume must the gas occupy.
How can I make up 100ml of a solution containing Compound A (solid, purity of 83.7%) at 90 ug/ml and compound B (liquid, density 1.12 and purity of 90.5) at 30 ug/mL for HPLC reference standard.
A chemist found that a certain amount of a CFC gas required 186 seconds to effuse through a porous plug when the pressure was held constant.
Consider an experimental run at 273k where the initial number of moles is actually 1.00 , and the final number of moles is 2.00 . Use the simulation to find the volume of 1.00 of helium at 273k and calculate the final volume.
Borane forms complexes with sulfides and amines. Draw a suitable structure to represent the complex formed between BH3 and dimethyl sulfide
