Balance the following redox equation using the smallest integers possible and select the correct coefficient for the hydrogen sulfite ion.MnO41-(aq) + HSO31-(aq) + H+(aq) ? Mn2+(aq) + SO42-(aq) + H2O(l)
A mixture of water and graphite is heated to 600 K. When the system comes to equilibrium it contains 0.13 mol of H2, 0.13 mol CO, 0.43 mol of H2O and some graphite
Aluminum sulphate is used in sand paper, among other uses. How many g of aluminum oxide dihydrate will be needed to produce 500 g of aluminum sulphate by the (unbalanced) reaction below? Al2O3 •2H2O + H2SO4 Al2(SO4)3 + H2O
determine the pressure exerted by 1.80 mol of gas in a 2.92-L container at 32.0 degrees celsius.
Referring to the standard enthalpies of formation, why would silver not dissolve in hydrochloric acid?
The laser beams are tightly focused. They briefly (for 0.5s) exert enough pressure to confine 500sodium atoms in a vloume of 1.0x10^-15m^3. The temperature of this gas is 0.00024K, the lowest temperature ever reached for a gas. Compute the root-me..
Draw the crossed aldol condensation product formed between benzaldehyde and acetone
consider a hydrogen atom in the ground state. what is the energy of its electron? Now consider an excited- state hydrogen atom. what is the energy of the electron in the n=2 level
What is the difference b/t a chiral molecule and enantiomers?
In an ionic compound, the size of the ions affects the internuclear distance (the distance between the centers of adjacent ions), which affects lattice energy (a measure of the attractive force holding those ions together).
what are the [H3O^+] and OH^-] for a solution with each of the following pH values? a)10.0 b)5.0 c)6.5 d)1.82
What mass of NaOH is needed to precipitate the Cd2+ ions from 68.0 mL of 0.500 M Cd(NO3)2 solution?
For the molecule shown below, choose all the statements that are true. Soluble is where at least 10 drops of the compound can be added to a particular solvent (in this case, water or hexane-- CH3CH2CH2CH2CH2CH3) and the result is one homogeneous l..
