On the basis of the solubility rules, write a balanced molecular equation for the precipitation reactions that take place when the following aqueous solutions are mixed. If no precipitation reaction is likely for the reactants given
What is the single-particle collisional frequency (for diatomic Nitrogen)at sea level, with 341 and 1.0 atm. The corresponding single-particle collisional frequency is reported as 10^10 s^-1.
along with chemical shift arguments and resonance theory, assign all of the peaks in the 1H and 13C NMR spectra of 4-propoxybenzaldehyde. Briefly explain you reasoning.
You pass a road sign saying "New York 115 km." If you drive at a constant speed of 65 mi/h, how long should it take you to reach New York? (Round to the nearest minute.)
The addition of H2 to double bonds is an important reaction used in the preparation of margarine from vegetable oils. If 50.0 mL of H2 and 50.0 mL of ethylene (C2H4)are allowed to react at 1.5 atm, the product ethane (C2H6) has a volume of 50.0 mL..
Chromium crystallizes in a body-centered cubic lattice (the Cr atoms are at the lattice points only). If the density of the metal is 7.19 g/cm3, what is the unit cell edge length in pm?
Find the entropy change of the system and of the surroundings if 3.000mole of water freezes reversibly at 1.000atm. the freezing temperature is 0.00C at this pressure, and the specific enthalpy change of fusion is equal to 79.7cal/gm at this tempe..
An empty 2.0 L soda bottle is tightly capped at 22 degrees Celsius and 650 mmHg. If the bottle is placed in water at 95 degrees Celsius, what is the pressure in the bottle?
water expands when it freezes. How much work is done by 100g of water expanding as it freezes at 0 degrees Celsius and pushes back the wall of a pipe that exerts 1070 atm of pressure?
show the path an electron takes when orbiting an atom describe regions of space in which one is most likely to find an electron.
If 2.00 moles of acetylene react completely with sufficient oxygen, how many grams of carbon dioxide are produced?
What would the reaction: Bi + excess Cl2 yield? I know Bismuth can only attach to I think 3 chlorides because of the inert pair effect but I guess that's the part I'm unsure about! So would it be BiCl3
