Draw the molecule by placing atoms on the grid and connecting them with bonds. Include all lone pairs of electrons and nonbonding electrons. Show the formal charges of all atoms in the correct structure.
A sample of gas occupies 721 mL at 1.00 atm. The pressure is increased to 1.1 atm (the temperature stays the same). What is the new volume of gas in mL?
Calculate the molarity of an aqueous solution that is 5.20% by mass CaCl2, given that the density of the solution is 1.19 g/mL
if you used the 8900 kilojoules you expend in energy in one day to heat 51000 of water at 20 what would be the rise in
the concentration of mg2 in a sample of water is 262 mmoll at what ph will 99 of the mg2 be precipitated as mgoh2? ksp
Offer an explanation for that fact that bromine adds to 2,3-dimethyl-2-butene 920,000 times faster than to ethylene, to produce the respective dibromides
Gold has a face-centered cubic arrangement with a unit cell edge length of 4.08 Angstrom. How many moles of gold fit in a sheet with a length of 51.6 nm, a width of 24.3 nm, and a thickness of 16.7 nm?
Calculate the number of moles of an ideal gas if it has a pressure of 1.02 atm, a volume of 2.76 L, and a temperature of 222 oC. Use R = 0.0821 L-atm/mol-K for the value of the gas constant.
considering the given chemical reaction and given information about the reaction asnbsp3 ag bg rarr 2 cg dl where
Determine the molar absorptivity of the acidic form of bromocresol green at 445 nm and at 615 nm. Given: Stock soln of bromoscresol green= 80.0 mg/L Molar Mass= 698.0 g/mol ?(445nm)=A445/[BG]
The rate of the reaction will increase if the pressure of the gases increases. The rate of the reaction will remain constant with increasing temperature. The rate of the reaction will increase as time increases.
