Ideal Gas Law & Reaction Stoichiometry Problem
I don't know how to determine how many grams of potassium chlorate decompose to form potassium chloride and 590 mL of O2 at 128 C, 729 torr.
Acid-Base Neutralization: NaOH and H2SO4
If a 26.85 mL of a standard 0.1650 M NaOH solution is required to neutralize 39.07 mL of H2SO4, what is the molarity of the acid solution?
How do I determine liters of hydrogen gas collected over water at 18 C and 725 mmHg when 0.79 g lithium reacts with water? (Aqueous lithium hydroxide also forms).
I am trying to determine how much heat is released for every 1.00 g of sucrosed oxidized from the following: Sucrose C12H22O11 is oxidized in the body by O2 that ultimately produces CO2(g) and H2O (g) and releases 5.64 E3 kJ/mol sucrose. This is what I come up with for the balanced equation: 1 C12H22O11 (s) + 12 O2 (g ...continues
When 39.5 mL of 0.525 M (H4)(SO4) is added to 39.5 mL of 1.05 M KOH in a coffee-cup calorimeter at at 23.50 C, the temperature rises to 30.17 C. Calculate the H of this reaction (Assume that the total volume is the sum of the individual volumes and that the density and specific heat capacity of the solution are the same as for ...continues
Desribing molecular forces of C5H6O
CH2=CH-CH=CH-CH=O THREE double bonds. We are asked to describe the bond and angle terms of this structure. I am not confident about what it is - it looks like a ring structure and I have been unable to find it using familiar web searches. I am assuming that the bond terms are C-C, C-H, C=O and C=C I have yet to figure out t ...continues
How do I calculate the molarity of a solution that is 3.0% hydrogen peroxide by weight (3 g H2O2 / 100g solution), assuming that the density of the solution is 1.00 g/ml?
We are asked to construct an energy level diagram (molecular orbital) for the molecule SO. We are then asked to comment on the ionic species of SO - bond order, bond distance etc. So far so good. Then we are asked the bond order of SO^4+ (assuming that it is formed). I have laboriously drawn out the whole thing (not attached ...continues
Ionic and covalent bonds story
Please help me with some ideas for this assignment - I will write it myself, just need some ideas: I need to create a creative story that uses the concepts and shows understanding of ionic and covalent bonds.
