Determine the volume of 0.235 M KOH solution required to neutralize 40 mL of 0.235 M H2SO4 sulfuric acid. The neutralization reaction is:H2SO4(aq) + 2KOH(aq) > K2SO4(aq) + 2H2O(l).
50.0000 g of a compound showed that it contained 12.7520 g C,3.2105 g H, and 34.037 g S. The molecular weight of this compound was determined in a seperate expierment and found to be 94.19u.
Ionization energy is the energy needed to eject an electron from an atom. Compute the ionization energy of a hydrogen atom in its first excited stat (n=2)
Determine the moles of benzene that would be needed to completely react with 0.445 moles of oxygen
Calculate the pH when 3.06 g of NaClO is added to 57.2 mL of 0.50 M HClO. Ignore any changes in volume.
It is used to control the ph and provide nutrients in the biological (microbial) treatment of municipal wastewater streams. Calculate the ratio of solubility of Mg(OH)2 dissolved in pure H20 to Mg(OH)2 dissolved in a 0.200 M NaOH solution?
How many moles of lithium nitrate are theoretically produced if we start with 3.4 moles of Ca(NO3)2 and 2.4 moles of Li3PO4? Reaction: 3Ca(NO3)2 + 2Li3PO4 ? 6LiNO3 + Ca3(PO4)2
A weak acid with the general formula of HA will react with a base, such as NaOH. Write the neutralization equation which describes the reaction.
Draw the structure(s) of the alkene(s) with the molecular formula C6H12 that have two methyl branches on the same carbon.
Beaker B contains 100.0g water heated to 20C.The contents of the two are mixed. What is the final temperature of contents? Assume no heat as lost.
If temperature and pressure remain constant, how does the volume of a gas sample vary withthe number of moles of gas present
Many power plants produce energy by burning carbon-based fuels, which also produces carbon dioxide. Carbon dioxide is a greenhouse gas, so over-production can have negative effects on the environment.
I have the worse trouble Newman Projections. Please help. Draw Newman projection formulas (looking at the bond between C-2 and C-3) for the three tartaric acids. Label pairs of enantiomers and diastereomers, as well as the meso forms.
