If all energy from the decay of the 40K could be captured and converted into electrical energy, how many bananas would be needed to power a 100 watts bulb? Begin you calculation with finding the amount of 40K in one banana and include t1/2 and the decay energy.
Acetic anhydride, like any anhydride, reacts with water to form a carboxylic acid. How is it then possible to carry out an acetylation in aqueous solution?
Explain how does the potential being greater than total energy affect the wave function. Does it affect how to solve the Schrodinger equation

When 1.0 m aqueous solutions of sodium carbonate as well as hydrochloric acid react it produces a carbon dioxide, water and sodium chloride. State the balanced chemical equation for the reaction described above (include states of matter)
The specific rate constant of the decomposition of azoisopropane at 270°C ??is 2.06x10-7s -1. Calculate the percentage of the original sample decomposed after 25 s. And the time Necessary for 95% of the sample to decompose.
Without consulting the table of acid-dissociation constants, match the following acids to the given Kal values. Drag the appropriate items to their respective bins.
When a sample of HI(g) (0.1192 mol/L) is placed in 110.0 L reaction vessel at 968.0 K and allowed to come to equilibrium the mixture contains 0.02028 mol/L of H2(g). What concentration (mol/L) of HI(g) reacted? 2HI(g) = H2(g)+I2(g)
