When doing resonance structures (with curved arrows showing the movement of electrons). What gets the positive charge and what gets the negative charge and why? Just need more help understanding how these structures work!
What mass of Ag2CO3(s) in grams is theoretically produced by mixing 125 mL of 0.315 M Na2CO3(aq) and 75.0 mL of 0.155 M AgNO3(aq)?.
Assuming that the outdoor formaldehyde concentration is neglible, calculate the steady-state concentration in the air inside the room. Does the concentration exceed the concentration (100 ppbv) considered to be the level of concern?
That a supercooled gas eventually phase separates is consistent with the 2nd Law of Thermodynamics because the phase separation lowers the Helmholtz free energy of the system
What is the mass (in kg) of helium if it filled a square room if the room has walls that are 9.5 feet high and 9.5 long and the density of helium is 0.18 g/L
25 cubic centimetres of potassium hydroxide solution were neutralized by 24.0 cubic cenimtre of 1M per decimetre hydrochloric acid. what is the concentration in molar per decimetre of alkali?
the particle , electron is in lowest possible enrgy state. what is the probability of finding electron between 0.2 nm to 0.35 nm from one side of the wall.?
The molecular formula is C4H10N2. •There are no ? bonds in the structure. •The compound has no net dipole moment. •The compound exhibits very strong hydrogen bonding.
using henrys law calculate the molar concentration of rm o2 in the surface water of a mountain lake saturated with air
A buffer solution is prepared by dissolving 1.51 g NH3 and 3.85 g (NH4)2SO4 in enough water to make 0.500 L of solution.
The substance CS2 has a melting point of -110.8°C and a boiling point of 46.3°C. Its density at 20°C is 1.26 g / cm3. It is highly inflammable. a.)Name this compound.
Reaction of SbF5 with HF produces octahedral SbF6- and a free proton (which is the reason for the super acid character of this combination). What is the formal charge on the central Sb atom in SbF6
combined in an 1 L reaction volume, what would be the concentration of B at equilibrium?
