Explain why you think that an acidic dichromate solution is not reduced by a tertiary alcohol such as t-butanol (CH3)3COH? Hint: C-H bonds are more reactive (weaker) than C-C bonds.
What values are quoted in handbooks for common hydrates of your cation?
what purpose does sodium carbonate serve during the extraction of caffeine from tea leaves?
Why is lip gloss long lasting containing petroleum? How many metric tonnes of 5%-S coal would be required to yield the H2SO4 needed to produce a 2.0-cm rainfall of pH 2.00 over an area of 100 square kilometers?
Compare this energy ( 23 Joules) to the amount of energy absorbed by a person's body if they jumped from a chair to the floor (assume that all of the energy from the fall is absorbed by the person and h=0.5 m).
A container with 1 mole of gas is expanded from 5 litres to 10 litres by adding more gas. the temperature and pressure are kept constant. how many moles of gas are present after the expansion.
The difference between these forces is why some solids dissolve by an exothermic reaction (release heat), while other solids absorb heat and cool the solution. For an ionic solid dissolving in water, briefly identify the attractive
Calculate the pH of a 100.0 mL buffer that is 0.158 M HClO and 0.099 M NaClO after adding 1.0 mL of 5.9 M NaOH solution. (Ka for HClO given at 2.9*10^-8 and assume the volume change of added NaOH solution is negligible)
how many moles of H30 or 0H must you add to a liter of a solution of a weak acid to change its pH from 3.25 to 3.65
A 0.456 gram sample of an unknown monoprotic acid (let's call it HZ) was dissolved in some water . Then the acidic solution was titrated to the equivalence point with 32.5 mL of 0.174 M KOH.
If the system below is at equilibrium in a closed vessel and a small amount of nitrous acid is added, what would be expected to happen
When a solution of copper(II) sulfate is mixed with a solution of sodium carbonate, a precipitate forms. Write each of the following equations for the reaction between copper(II) sulfate and sodium carbonate.
